AB  - The aim of this study was to find the chemical parameters for the differentiation of plum cultivars grown along the fjord areas of Western Norway and Eastern Norway, having specific agroclimatic conditions. Chemical analysis of the fruits confirmed the contents of 13 quantified elements, 22 sugar compounds, 11 organic acids, 19 phenolic compounds, and antioxidant activity in 68 plum cultivars. Dominated contents were noted for nitrogen (with the maximum mean value of 3.11%), potassium (8055.80 mg/kg), and phosphorous (7878.88 mg/kg). Averagely, the highest level of sugars was determined for glucose (244.46 g/kg), fructose (197.92 g/kg), sucrose (208.25 g/kg), and sorbitol (98.02 g/kg), organic acids for malic acid (24.06 g/kg), and for polyphenol compounds were 5-O-caffeoylquinic acid (66.31 mg/kg), and rutin (58.06 mg/kg). Applied principal component analysis has been useful for distinguishing the plum cultivars from three areas in Norway where copper, iron, potassium, magnesium, manganese, and sodium; sucrose, ribose, maltose, and raffinose; p-hydroxybenzoic acid, rutin, ferulic acid, kaempferol 7-O-glucoside, p-coumaric acid, and 5-O-caffeoylquinic acid were the most influential. In regard to human health and future breeding work that will have the aim to produce functional food with high health-related compounds, the plum cultivar ‘Mallard’ should be underlined due to the high level of elements, ‘Valor’ due to high sugar content, ‘Helgøyplomme’ due to content of organic acids, and ‘Diamond’ due to the content of phenolic compounds. © 2023 by the authors.

AB  - The main objective of this study is to determine the possibility of predicting the impact of land use and soil type on concentrations of heavy metals (HMs) and phthalates (PAEs) in soil based on an artificial neural network model (ANN). Qualitative analysis of HMs was performed with inductively coupled plasma-optical emission spectrometry (ICP/OES) and Direct Mercury Analyzer. Determination of PAEs was performed with gas chromatography (GC) coupled with a single quadrupole mass spectrometry (MS). An ANN, based on the Broyden-Fletcher-Goldfarb-Shanno (BFGS) iterative algorithm, for the prediction of HM and PAE concentrations, based on land use and soil type parameters, showed good prediction capabilities (the coefficient of determination (r(2)) values during the training cycle for HM concentration variables were 0.895, 0.927, 0.885, 0.813, 0.883, 0.917, 0.931, and 0.883, respectively, and for PAEs, the concentration variables were 0.950, 0.974, 0.958, 0.974, and 0.943, respectively). The results of this study indicate that HM and PAE concentrations, based on land use and soil type, can be predicted using ANN.

AB  - This research investigated a Balkan endemic species, Achillea clypeolata, collected from two locations (Dobrostan and Ivaylovgrad) in Bulgaria and two locations (Ozren and Rtanj) in Serbia. The goal was to compare the essential oil (EO) of A. clypeolata from these four localities. The EO was isolated from dry aboveground plant parts by hydrodistillation, and the identification of the EO constituents was carried out by GC-MS analyses. Principal Component Analysis (PCA), correlation analysis, and an unrooted cluster tree were used to define distinctions in the presence of volatile compounds in A. clypeolata EO. Results showed that A. clypeolata of Serbian origin (Ozren and Rtanj) contained 1,8-cineole as the main constituent, and belonged to the previously described 1,8-cineole as a dominant compound in the EO profile. On the other hand, the results from Bulgaria show an evident chemical diversification within the A. clypeolata species, as 1,8-cineole (23.2%), camphor (5.0%) and borneol (8.9%) prevailed in the EO of the studied samples collected from Ivaylovgrad, while borneol (22.6%), β-eudesmol (12.7%) and elemol (7.8%) were the main ones in the EO from Dobrostan. In sillico analysis revealed the high anti-inflammatory potential of A. clypeolata, which may be highly diverse depending on the population and active compounds it contains.

AB  - Purpose To anticipate the impact of illegal landfills, development of new models should become a part of environmental risk management strategies. One of such approaches includes applications of the artificial neural network (ANN). The main objective of this study was to elucidate the impact of illegal landfilling on the surrounding soil environment and human health, as well as to establish an artificial neural network (ANN) models for predicting the hazards of illegal landfilling as an effective tool in decision-making and environmental risk management.Methods The identification of heavy metals source in soil was performed by principal component analysis (PCA). To assess the sensitivity of the soil ecosystem to heavy metal concentrations, Soil Quality standards and quantitative indices were used. The possible health effects were valued using the average daily doses (ADDs), hazard quotient (HQ), hazard index (HI), and carcinogenic risk (CR). ANN modeling was used for the prediction of heavy metal concentrations in the soil based on landfill size, municipality size, the number of residents, plant species, soil, and landform types.Results The average values of the pollution indexes for Cd were in the moderately contaminated and very high contamina tion categories. The HQ values were lower than the safe level. Cr and Pb posed a significant CR for adults and children, and Ni for children. The ANN models have exhibited good generalization power and accurately predicted the output parameters with a high value of the coefficient of determination.Conclusion Concerning heavy metal concentrations, illegal landfills near agricultural soil have a significant impact on the soil ecosystem and people’s health. The developed ANN models can be applied generally to anticipate the heavy metal concentrations in soil, according to the before mentioned input parameters, with high accuracy.

AB  - Background and Aims: In the global distribution of persistent organic pollutants (POPs) forests play a key role due to the forest canopy effect. In this study, mountain beech forests were selected to identify the level and distribution of selected POPs. 
Methods: Organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) were analyzed by capillary gas chromatography with an electron capture detector (GC–ECD). Analysis of polychlorinated biphenyls (PCBs) was performed by gas chromatography with a mass spectrometry detector (GC–MS). The polycyclic aromatic hydrocarbons (PAHs) were analyzed by liquid chromatography with a diode array detector (HPLC–DAD).
Results: The total ∑20OCP concentrations in the soil from mountain beech forests at a depth of 0 – 40 cm ranged from 24.46 μg kg −1 to 331.11 μg kg −1, and at a depth of 40 – 80 cm from 15.80 μg kg−1 to 247.12 μg kg −1. The mass concentration for ∑ 6PCB ranges from 9.21 to 95.28 μg kg−1 in the surface soil layer and from 8.07 to 66.56 μg kg −1 in the soil sub.layer. The total concentration of ∑7PBDE congeners measured in soil samples from mountain beech forests
across Europe was from 1.38 to 29.68 μg kg−1 in the surface soil layer and from 1.01 to 53.31 μg kg−1 in the soil sublayer. The total concentration of ∑ 16PAH varied from 271.52 to 1154.52 μg kg−1 in the surface soil layer and from 318.95 to 1052.54 μg kg −1 in the soil sublayer.
Conclusion: The results of this study can serve as an important basis for international, national, and regional measures of environmental protection of beech forests from POPs pollution.

abstract = "Background and Aims: In the global distribution of persistent organic pollutants (POPs) forests play a key role due to the forest canopy effect. In this study, mountain beech forests were selected to identify the level and distribution of selected POPs. 
Methods: Organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDEs) were analyzed by capillary gas chromatography with an electron capture detector (GC–ECD). Analysis of polychlorinated biphenyls (PCBs) was performed by gas chromatography with a mass spectrometry detector (GC–MS). The polycyclic aromatic hydrocarbons (PAHs) were analyzed by liquid chromatography with a diode array detector (HPLC–DAD).
Results: The total ∑20OCP concentrations in the soil from mountain beech forests at a depth of 0 – 40 cm ranged from 24.46 μg kg −1 to 331.11 μg kg −1, and at a depth of 40 – 80 cm from 15.80 μg kg−1 to 247.12 μg kg −1. The mass concentration for ∑ 6PCB ranges from 9.21 to 95.28 μg kg−1 in the surface soil layer and from 8.07 to 66.56 μg kg −1 in the soil sub.layer. The total concentration of ∑7PBDE congeners measured in soil samples from mountain beech forests
across Europe was from 1.38 to 29.68 μg kg−1 in the surface soil layer and from 1.01 to 53.31 μg kg−1 in the soil sublayer. The total concentration of ∑ 16PAH varied from 271.52 to 1154.52 μg kg−1 in the surface soil layer and from 318.95 to 1052.54 μg kg −1 in the soil sublayer.
Conclusion: The results of this study can serve as an important basis for international, national, and regional measures of environmental protection of beech forests from POPs pollution.",

AB  - A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made from poly(dimethylsiloxane)-based macrodiol as the soft segment and 4,4′-methylenediphenyldiisocyanate and hyperbranched polyester of the third pseudo generation as the hard segment. Nanocomposites were obtained by dispersion of organically modified montmorillonite (Cloisite 30B) nanofiller (0.5 wt%). The influence of the soft segment content on the functional properties of PUN-NCs was studied by Fourier transform infrared (FTIR), small-angle and near wide-angle X-ray scattering (SWAXS), thermogravimetric analysis (TGA), dynamic mechanical thermal analyses (DMTA), differential scanning calorimetry (DSC), nanoindentation, atomic force microscopy (AFM), scanning electron microscopy (SEM), and swelling behavior, water absorption and contact angle measurements. The biodegradation process was evaluated using mixed cultures of microorganisms that originated from soil. Mechanically strong PUN-NC materials in the form of films were obtained, pointing to good dispersion and the existence of exfoliated morphology of Cloisite 30B within the PUN matrix, and the nanocomposites with the abovementioned characteristics were obtained as a function of the soft segment content. The decrease of the soft segment content induced a higher degree of phase separated microstructure, increase of Young's modulus, hardness, plasticity, storage modulus, glass transition temperature, surface free energy and swelling ability in tetrahydrofuran, but at the same time, it is responsible for the decrease of crosslinking density and hydrophobicity of PUN-NCs. By choosing adequate soft segment content, the prepared materials can potentially be designed for coating applications, such as top coating materials in environmental conditions.

AB  - Unlike other studies that only determined the chemical composition of essential oils depending on their geographic origin, this research investigated the effect of weather conditions (temperature, precipitation, and insolation) on the chemical composition of Nepeta nuda L. essential oil. The collection of wild-growing N. nuda was carried out during three successive years, 2019, 2020, and 2021 at Rtanj Mountain (Serbia) on the same date (July 7th). Essential oil extraction from the plant was performed by hydro-distillation. After gas chromatographic-mass spectrometric analysis, a total of 102 volatile compounds were separated from N. nuda, during the observed period, 28 were unidentified, compromising between 5.0% and 8.7%, depending on the year. A multiple linear regression model was created, and statistical analyses were performed to provide knowledge about the prediction, feature profile, and the similarity in contents of active compounds of the N. nuda essential oil. The influence of temperature on the accumulation of the most abundant component, 1,8-cineole, was positive, while the impact of precipitation and insolation was negative. According to the cluster tree, there are four chemotypes of N. nuda essential oil: with nepetalactone, 1,8-cineole, mixed (nepetalactone+1,8-cineole+germacrene D), and nonspecific chemotypes. Bearing in mind that the biological activity of a raw material depends on the chemotype and environmental factors, this is a topic that deserves a more detailed approach. The N. nuda and its essential oil are promising materials with high biological potential, and these deserve further detailed investigation.

AB  - Salvia sclarea L. or clary sage is cultivated worldwide in temperate and sub-tropical climates, as an ornamental and essential oil (EO) bearing plant. EO is obtained from fresh spikes in full flowering stage and is recognized as an important commercial product for food, beverage and cosmetic industries. This study investigated the EO composition of S. sclarea grown in Serbia (Southeast Europe) obtained by two different methods, steam (SD) and hydrodistillation (HD). GC-MS analysis identified oxygenated monoterpenes as the main class of compounds for all EOs (between 81.8% and 88.2% depending on the distillation process). The most abundant oxygenated monoterpenes were linalyl acetate and linalool. In addition, in vitro antimicrobial (modified resazurin microtitre-plate assay) and antioxidant activities (DPPH• assay) and total polyphenol content of obtained EOs were also evaluated. According to the assay used for the evaluation of the antibacterial activity, Gram-negative bacteria were more sensitive to S. sclarea EO in comparison to Gram-positive bacteria. EOs exhibited low antioxidant capacity, below 3% neutralized DPPH• radicals, reaching up to approximately 400 µg AAE mL-1. This study also investigated a possibility for predicting retention indices (RIs) of compounds isolated from EOs. In total, 78 experimentally obtained RIs were applied to construct the prediction model. The quantitative structure-chromatographic retention relationship (QSRR) model was used to anticipate the experimentally obtained RIs. Five molecular descriptors were selected by factor analysis and genetic algorithm to predict RIs. The obtained accuracy of the QSRR model reached r2 =.912, which showed that these models might be applied for predicting retention indices.

AB  - The most abundant volatile compounds of sweet wormwood (Artemisia annua L.) essential oil were artemisia ketone (25.4 %) and trans-caryophyllene (10.2 %), followed by 1,8-cineole, camphor, germacrene D and β-selinene. The major volatile compounds in the hydrosol were camphor (25.1 %), 1,8-cineole (20.5 %) and artemisia ketone (10.7 %), followed by trans-pinocarveol and yomogi alcohol. Tested essential oil was rich in oxygenated monoterpenes and sesquiterpene hydrocarbons, while the former were identified as the major class of volatile compounds in the hydrosol, due to higher water solubility. Classification of all sweet wormwood chemotypes, according to essential oil composition, in available literature (17 studies and 61 accessions) could be done according to four chemotypes: artemisia ketone+artemisia alcohol (most abundant), artemisia ketone, camphor and nonspecific chemotype. According to this classification, essential oil of sweet wormwood from this study belongs to artemisia ketone (content varied between 22.1 and 55.8 %). Bearing in mind that hydrosols are a by-product of industrial production of essential oils, and the fact that sweet wormwood hydrosol has high contents of camphor, 1,8-cineole and artemisia ketone, there is a great potential for the use of this aromatic plant primary processing waste product as a water replacement in cosmetic industry, beverages flavoring, for food preservation, as well as in post-harvest pre-storage treatments in organic agriculture.

AB  - Lavandula sp. essential oil and hydrolate are commercially valuable in various industry
branches with the potential for wide-ranging applications. This study aimed to evaluate the quality
of these products obtained from L. x intermedia cv. ‘Budrovka’ for the first time cultivated on Fruška
Gora Mt. (Serbia) during three successive seasons (2019, 2020, and 2021). Essential oil extraction
was obtained by steam distillation, and the composition and influence of weather conditions were
also assessed, using flowering tops. The obtained essential oils and hydrolates were analysed by
gas chromatography with a flame ionization detector (GC-FID) and gas chromatography coupled to
mass spectrometry (GC-MS). A linear regression model was developed to predict L. x intermedia cv.
‘Budrovka’ essential oil volatile compound content and hydrolate composition during three years,
according to temperature and precipitation data, and the appropriate regression coefficients were
calculated, while the correlation analysis was employed to analyse the correlations in hydrolate
and essential oil compounds. To completely describe the structure of the research data that would
present a better insight into the similarities and differences among the diverse L. x intermedia cv.
‘Budrovka’ samples, the PCA was used. The most dominant in L. intermedia cv. ‘Budrovka’ essential
oil and hydrolate were oxygenated monoterpenes: linalool, 1,8-cineole, borneol, linalyl acetate, and
terpinene-4-ol. It is established that the temperature was positively correlated with all essential oil
and hydrolate compounds. The precipitations were positively correlated with the main compounds
(linalool, 1,8-cineole, and borneol), while the other compounds’ content negatively correlated to
precipitation. The results indicated that Fruška Gora Mt. has suitable agro-ecological requirements
for cultivating Lavandula sp. and providing satisfactory essential oil and hydrolate.

terpinene-4-ol. It is established that the temperature was positively correlated with all essential oil
and hydrolate compounds. The precipitations were positively correlated with the main compounds
(linalool, 1,8-cineole, and borneol), while the other compounds’ content negatively correlated to
precipitation. The results indicated that Fruška Gora Mt. has suitable agro-ecological requirements
for cultivating Lavandula sp. and providing satisfactory essential oil and hydrolate.",

AB  - This study aimed to investigate the chemical composition of steam distillate essential oil and corresponding hydrolate obtained from S. officinalis grown in Serbia, as well as the influence of weather conditions (temperature and precipitations) on their chemical profiles. Furthermore, their antimicrobial activity was investigated in vitro. The main compounds in essential oil were cis-thujone, followed by camphor, trans-thujone, and 1,8-cineole, while hydrolate was slightly different from the essential oil, with camphor, cis-thujone, and 1,8-cineole as the main compounds. Among the eight respiratory-associated microorganisms, Klebsiella oxytoca was the most sensitive to the tested EOs (minimum inhibitory concentration (MIC)/minimal bactericidal/fungicidal concentration (MBC/MFC) were 14.20 and 28.4 μL mL−1, respectively). MIC and MBC values of other tested bacteria ranged between 28.40 and 227.25 μL mL−1 while for Candida albicans MIC/MFC ranged from 28.40/56.81 to 56.81–113.63 μL mL−1. Antibiotic susceptibility patterns for the analyzed eight respiratory-associated microorganisms showed an intermediate level of resistance to commonly used antibiotics such as ampicillin, levofloxacin, and ciprofloxacin. As a preliminary approach to the antimicrobial profiling of the tested EO, the obtained results revealed that the tested samples possess remarkable antibacterial activities and could be used to develop pharmaceutical formulations as an alternative to conventional antibiotic therapy.

AB  - This study presents a detailed characterization of 27 honey samples from the Tara Mountain region in Serbia using different comprehensive techniques and methods. The types of the honey samples were defined as monofloral (4 samples), honeydew (5 samples) and polyfloral (18 samples) honey based on determined polyphenol content, antioxidant activity, electrical conductivity and melissopalynological analyses. Physicochemical parameters such as pH (4.13–4.94), diastase activity (24.20–41.70 DN), acidity (14.60–29.70 meq/kg), content of 5-(hydroxymethyl)furfural (in range below 5, up to 16.90 mg/kg), sucrose (0.20–3.90 g/100 g), and moisture content (15.01–19.23%) confirmed the required quality of the honey samples. Sensory analysis revealed honey characteristics favorable to consumers. Analyses of 19 phenolic compounds using ultra-high-performance liquid chromatography with a diode-array detection and triple quadrupole mass spectrometry (UHPLC-DAD-MS/MS) revealed six phenolic acids and 13 other compounds from the group of flavonoids and their glycosides. In all the samples the highest content was determined for p-coumaric acid, followed by caffeic acid and pinocembrin. Besides total phenolic content and radical scavenging activity, antimicrobial activity was also examined. Most honey samples showed bactericidal activity against Staphylococcus aureus and bacteriostatic activity against Escherichia coli, while none of the honey samples inhibited the growth of Candida albicans. Chemometric analyses were applied for an in-depth study of the results to further evaluate the characteristics of the honey samples studied. Principal component analysis (PCA) was used for assessing the differences in physicochemical parameters, polyphenols content and antioxidant capacity between honey samples. The unrooted cluster tree was used to group the samples based on the melissopalynological analyses.

AB  - Raspberries are considered valuable fruits due to their high levels of nutrients and phytochemicals, which have many beneficial effects on humans. As many external factors affect the composition of these fruits (the type of cultivation, soil characteristics, ripeness, storage time and post-harvest technologies, cultivar/genotype, and climatic conditions), the goal of this study was to analyze different raspberry cultivars grown in Norway. Considering that Norway is a country with specific climatic conditions, as well as has a limited period of fruit vegetation, another important goal of this study was also to compare raspberries from different Norwegian areas, as well as different grown cultivars. Modern analytical techniques, such as high-performance anion-exchange liquid chromatography with pulsed amperometric detection (HPEAC-PAD), ultra-high-performance liquid chromatography with diode array detector coupled to triple quadrupole mass spectrometry (UHPLC-DAD MS/MS), and inductively coupled plasma–optical emission spectrometry (ICP-OES), provided a detailed examination of the raspberry extract samples. Based on their high levels of minerals (especially N, P, and K), organic acids (predominantly citric and malic acids), sugars (glucose, fructose, sucrose, and galactose), and polyphenols (ellagic acid, syringic acid, quercetin, and rutin), Norwegian raspberries could be considered fruits with increased health-beneficial compounds. The chemical composition of the studied cultivars depended on the locality of growth.

AB  - Using modern analytical techniques, a comprehensive study of the chemical composition of fruits from apple cultivars grown in Western Norway during 2019 and 2020 was done. Metals, sugars, organic acids, antioxidant tests, and polyphenol content have been observed. In all investigated samples, the most dominant sugars were glucose, fructose, and sucrose. Among 11 tested organic acids, the dominant was malic acid, followed by citric and maleic acid. The most common metal was potassium, followed by magnesium and zinc. The quantification of polyphenols showed that among the 11 quantified polyphenols, chlorogenic acid, quercetin 3-O-rhamnoside, quercetin 3-O-glucoside, quercetin, and phlorizin were the most abundant. A detailed study of the polyphenolic profile of nine investigated apple samples provided 30 identified polyphenolic compounds from the class of hydroxybenzoic and hydroxycinnamic acids, flavonoids, and dihydrochalcones. In addition to the identified 3-O-caffeoylquinic acid, its two isomers of 5-O-caffeoylquinic acid and three esters were also found. Present polyphenols of the tested apples provided significant data on the quality of Norwegian apples, and they contribute to the distinguishing of these apple samples.

AB  - The osmotic dehydration (OD) of celery root in sugar beet molasses was studied at three temperatures (20, 35, and 50 °C) and three immersion periods (1, 3, and 5 h) in order to examine the changes in antioxidant potential and phenolic profile of celery root throughout the process. The antioxidant capacity (AOC) of dehydrated samples was evaluated by spectrophotometric and polarographic assays, the total phenolic content by the Folin-Ciocalteu method, and the individual phenolic compounds by HPLC-DAD. As a result of OD in molasses, the AOC and phenols content in samples increased proportionally to the augmentation of temperature and the immersion time. Vanillic acid, syringic acid, and catechin were detected in dehydrated samples as a result of transfer from molasses. Compared to fresh celery root, the content of identified phenols in osmodehydrated samples was improved from 1.5 to 6.2 times. Strong correlations between applied assays were obtained, except for the DPPH. Based on the correlation analysis chlorogenic acid, gallic acid, chrysin, catechin, and kaempferol showed the greatest contribution to the overall AOC of osmodehydrated celery root. Molasses, an agro-industrial waste from sugar production, could be valorized as a valuable osmotic solution.

AB  - Thermoplastic poly(urethane-siloxane)/organoclay nanocomposites (TPU NCs) with different hard segment content (20–55 wt. %) were prepared by in situ polymerization in the presence of organically modified montmorillonite as a nanofiller (Cloisite 30B; 1 wt. %). Hydroxyl-terminated ethoxypropyl- poly(dimethylsiloxane) was used as soft segment, while 4,4'-methylenediphenyl diisocyanate and 1,4-butanediol were the hard segment components. The study of the influence of the hard segment content on the functional properties of TPU NCs was performed by Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), dynamic mechanical thermal analyses (DMTA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), water contact angle and water absorption tests. The results revealed that TPU NCs with the increasing hard segment content exhibit higher values of degree of microphase separation, melting temperature of the hard segments, degree of crystallinity, storage modulus (except for TPU NC-55), but lower thermal stability and hydrophobicity. TPU NC films were hydrophobic and their free surface energy was in the range from 17.7 to 24.9 mJ m-2. This work highlights how the composition of TPU NCs would affect their functional properties and provide an additional composition intended for designing advanced TPU NC materials for special biomedical applications.

Проучавање утицаја садржаја тврдог сегмента на функционална својства TPU NCs је испитивано FTIR спектроскопијом, дифракцијом X-зрака (XRD), микроскопијом атомских сила (AFM), скенирајућом електронском микроскопијом (SEM), динамичко механичко термичком анализом (DMTA), диференцијално скенирајућом калориметријом (DSC), термогравиметријском анализом (TGA), тестовима одређивања контактног угла са водом и апсорпције воде. Резултати су показали да TPU NCs са већим садржајем тврдих сегмената показују веће вредности степена микрофазне сепарације, температуре топљења тврдих сегмената, степена кристалиничности, модула сачуване енергије (осим за TPU NC-55), али нижу термичку стабилност и хидрофобност.

AB  - Essential oil (EO) obtained by hydrodistillation in a Clevenger-type apparatus from aerial parts of Nepeta cataria L. var. citriodora (Becker), cultivated in Serbia was subjected to gas chromatography-mass spectroscopy (GC-MS) to determine the composition. Furthermore, N. cataria var. citriodora essential oil was
tested to determine its antimicrobial, antioxidant, antihyperglycemic and anti-inflammatory activities in vitro.
The antimicrobial activity was tested by broth microdilution method against 16 bacterial strains from American Type Culture Collection (ATCC). Four common tests for measuring in vitro antioxidant activity were used: 2, 2-diphenyl-1-picrylhydrazyl assay (DPPH), reducing power (RP), 2,2-azino-bis-3-ethylbenzothiazoline-
6-sulfonic acid (ABTS) and β-carotene bleaching assay (BCB). Antihyperglycemic activity was examined by using α-glucosidase inhibitory potential (AHgA), while anti-inflammatory activity (AIA) was determined by protein denaturation bioassay, using egg albumin. In total, 36 compounds were isolated and detected by GC-MS technique in N. cataria var. citriodora EO. The EO is mainly comprised of oxygenated monoterpenes (93.1%), and the main compounds were two monoterpenoid alcohols, nerol (38.5%) and geraniol (24.9%), followed by two aliphatic aldehyde, geranial (14.6%) and neral (11.0%). Antimicrobial activity of this EO shows growth inhibition of all tested bacteria strains, and exhibited good antioxidant, antihyperglycemic and anti-inflammatory activities. The EO obtained from N. cataria var. citriodora grown in Serbia shows valuable biological activity, indicating its potential for use as a supplement in everyday diet and as a natural preservative in food industry.

AB  - Ecological conditions of the growing areas, growing practices as well as harvest and postharvest processing influence the yield and quality of chamomile. The aim of this research was to determine the influence of chamomile separation methods, as postharvest treatments, on the essential oil quality and content, with a view to improve current primary processing of this valuable medicinal plant. In order to explain the structure of laboratory data that would give deeper assessment of similarities among various samples of chamomile essential oil, PCA was employed. Tested results showed that separation of chamomile plant material, as postharvest and pre-drying treatment, had significant influence on the number of identified compounds in the chamomile essential oil. The highest content of individual essential oil compounds had chamomile flowers with short stems, especially α-bisabolol, chamazulene, Z-spiroether and E-β-farnesene. In the essential oil obtained from chamomile flowers with long stems, content of α-bisabolol and chamazulene were significantly lower, while E-β-farnesene and Z-spiroether contents were significantly higher. Furthermore, in the essential oil obtained from chamomile plant material without separation, the lowest content of αbisabolol and Z-spiroether, and the highest content of E-β-farnesene were recorded. The correlation analysis was performed to investigate the likeness in the amounts of the active compounds of essential oil from differently processed chamomile samples. All these results indicate the importance of precise and controlled postharvest treatments, since it clearly affects the essential oil quality and content in the primary processing of this valuable medicinal plant.

AB  - This paper is a study of the chemical composition of Hyssopus officinalis ssp. Officinalis grown during three years (2017-2019) at the Institute of Field and Vegetable Crops Novi Sad (Vojvodina Province, Serbia). Furthermore, comparisons with ISO standards during the years were also investigated, as well as a prediction model of retention indices of compounds from the essential oils. An essential oil obtained by hydrodistillation and analysed by GC-FID and GC-MS was isopinocamphone chemotype. The gathered information about the volatile compounds from H. officinalis was used to classify the samples using the unrooted cluster tree. The correlation analysis was applied to investigate the similarity of different samples, according to GC-MS data. The quantitative structure- retention relationship (QSRR) was also employed to predict the retention indices of the identified compounds. A total of 74 experimentally obtained retention indices were used to build a prediction model. The coefficient of determination for the training cycle was 0.910, indicating that this model could be used for the prediction of retention indices for H. officinalis essential oil compounds.

AB  - In the essential oil of yarrow (Achillea millefolium L. sensu lato) collected from natural popula-
tion on Mt. Rtanj (Serbia) and distilled by Clevenger apparatus 104 compounds were detected, and

the most abundant were camphor (9.8%), caryophyllene oxide (6.5%), terpinen-4-ol (6.3%) and 1,8-

cineole (5.6%). The quantitative structure-retention relationship (QSRR) model was employed to pre-
dict the retention indices, using four molecular descriptors selected by factor analysis and a genetic

algorithm. The coefficients of determination reached the value of 0.862, demonstrating that this mo-
del could be used for prediction purposes.

AB  - The aim of this study was the prediction model of retention indices of compounds from the aboveground parts of Achillea clypeolata Sibth. & Sm. essential oil, obtained by hydrodistillation and analysed by GC-MS. The quantitative structure-retention relationship analysis was applied in order to anticipate the retention time of the obtained compounds. The selection of the seven molecular descriptors was done by a genetic algorithm. The chosen descriptors were uncorrelated and were used to construct an artificial neural network. A total of 40 experimentally obtained retention indices was used to build this prediction model. The coefficient of determination for the training, testing and validation cycles were: 0.950, 0.825 and 1.000, respectively, indicating that this model could be used for prediction of retention indices for A.

AB  - Marrubium vulgare is a cosmopolitan medicinal plant from the Lamiaceae family, which produces structurally highly diverse groups of secondary metabolites. A total of 160 compounds were determined in the volatiles from Serbia during two investigated years (2019 and 2020). The main components were E-caryophyllene, followed by germacrene D, α-humulene and α-copaene. All these compounds are from sesquiterpene hydrocarbons class which was dominant in both investigated years. This variation in volatiles composition could be a consequence of weather conditions, as in the case of other aromatic plants. According to the unrooted cluster tree with 37 samples of Marrubium sp. volatiles from literature and average values from this study, it could be said that there are several chemotypes: E-caryophyllene, β-bisabolene, α-pinene, β-farnesene, E-caryophyllene + caryophyllene oxide chemotype, and diverse (unclassified) chemotypes. However, occurring polymorphism could be consequence of adaptation to grow in different environment, especially ecological conditions such as humidity, temperature and altitude, as well as hybridization strongly affected the chemotypes. In addition, this paper aimed to obtain validated models for prediction of retention indices (RIs) of compounds isolated from M. vulgare volatiles. A total of 160 experimentally obtained RIs of volatile compounds was used to build the prediction models. The coefficients of determination were 0.956 and 0.964, demonstrating that these models could be used for predicting RIs, due to low prediction error and high r2 .

AB  - The aim of this study was to predict the retention indices of chemical compounds found in the
aerial parts of Origanum vulgare subsp. vulgare essential oil, obtained by hydrodistillation and
analyzed by GC-MS. A total number of 28 compounds were detected in the essential oil. The
compounds with the highest relative concentrations were germacrene D (21.5%), 1,8-cineole
(14.2%), sabinene (14.0%) and trans-caryophyllene (13.4%). The retention time was predicted by
using the quantitative structure–retention relationship, using seven molecular descriptors chosen
by factor analysis and genetic algorithm. The chosen descriptors were mutually uncorrelated, and
they were used to develop an artificial neural network model. A total number of 28 experimentally
obtained retention indices (log RI) were used to set up a predictive quantitative structure-retention
relationship model. The coefficient of determination for the training cycle was 0.998, indicating
that this model could be used for predicting retention indices for O. vulgare subsp. vulgare
essential oil compounds.

AB  - The objective of this study was to evaluate wild growing Satureja kitaibelii, Thymus serpyllum,
Origanum vulgare, Achillea millefolium and Achillea clypeolata with respect to their essential oil (EO)
content, composition and antimicrobial activity. The five species were collected at Mt. Rtanj and the
village of Sesalac, Eastern Serbia. The main EO constituents of Lamiaceae plants were p-cymene
(24.4%), geraniol (63.4%) and germacrene D (21.5%) in Satureja kitaibelii, Thymus serpyllum and
Origanum vulgare ssp. vulgare, respectively. A. millefolium EO had multiple constituents with major
ones being camphor (9.8%), caryophyllene oxide (6.5%), terpinen-4-ol (6.3%) and 1,8-cineole (5.6%),
while the main EO constituents of A. clypeolata were 1,8-cineole (45.1%) and camphor (18.2%).
Antimicrobial testing of the EO showed that Staphylococcus aureus (Gram-positive) was more sensitive
to all of the tested EOs than Escherichia coli (Gram-negative). S. kitaibelii EO showed the highest
antimicrobial activity against both tested bacterial strains. This is the first study to characterize
the EO composition and antimicrobial activity of these five medicinal species from Eastern Serbia
in comparison with comprehensive literature data. The results can be utilized by the perfumery,
cosmetics, food and pharmaceutical industries, but also for healing purposes in self-medication.
