AB  - The concept of the genus Clinopodium L. has changed considerably since its first description. Most of the currently accepted species of the genus have traditionally been treated as separate genera in the group Satureja sensu lato: Clinopodium L., Calamintha sensu Miller or Moench, and Acinos sensu Miller or Moench. This study aimed to gain a better insight into the species diversity of Clinopodium L. from the Balkans by analyzing the taxa that have traditionally been placed in separate genera. The alkane profile and the micromorphological characteristics of the leaves are analyzed. The leaves are visualized using scanning electron microscopy, and alkanes are isolated using n-hexane as a solvent and analyzed using gas chromatography/mass spectrometry. The alkane profile showed the differentiation of the Acinos-group from the other taxa based on the dominant n-C31, while most of the other taxa contained n-C33 as the dominant alkane. The micromorphological features also showed clear differences between the previously recognized genera, especially in the capitate trichomes. The results showed that micromorphological patterns are highly variable in certain groups of the genus Clinopodium.

AB  - Chemotaxonomy presents various challenges that need to be overcome in order to obtain valid and reliable results. Individual genetic and environmental variations can give a false picture and lead to wrong conclusions. Applying a holistic approach, based on multivariate data analysis, these challenges can be overcome. Thus, a metabolomics approach has to be optimized depending on the subject of research. We used 1H NMR-based metabolomics as a potential chemotaxonomic tool on the selected Euphorbia species growing wild in Serbia. Principal components analysis (PCA), soft independent modeling by class analogy (SIMCA) and Orthogonal Projections to Latent Structures Discriminant Analysis (OPLS-DA) were used to analyze obtained NMR data in order to reveal chemotaxonomic biomarkers. The standard protocol for plant metabolomics was optimized aiming to extract more specific metabolites, which are characteristic for the Euphorbia genus. The obtained models were validated, which revealed that variables unique for each species were associated with certain classes of molecules according to literature data. In E. salicifolia, acacetin-7-O-glycoside (not found before in the species) was detected, and the structure of the aglycone part was solved based on 2D NMR data. In the presented paper, we have shown that metabolomics can be successfully used in Euphorbia chemotaxonomy.

AB  - Introduction: Chokeberry is a plant belonging to the family Rosaceae which has a long history of edible and medicinal use. The aims of this study are: i) to investigate of HPTLC profile of the berry samples using HPTLC technique based metabolomics approach, ii) to determine the botanical origin of investigated chokeberry adulterations iii) to identify the most important botanical markers responsible for classification. Methods: A simple, rapid, and high-throughput planar chromatography (HPTLC) method was applied in combination with multivariate techniques for differentiating chokeberry samples and identification of the main metabolites of chokeberry and four common adulterants. Images of HPTLC chromatograms obtained using two different detections i.e. visible light and derivatization with natural products reagent were used as a dataset for multivariate analysis. Results: Principal component analysis and Orthogonal Partial Least Squares Discriminant Analysis confirmed the discrimination of five botanically different samples and recognized their main markers such as responsible for differences between chokeberry and four common adulterants. Conclusion: The obtained results showed that the HPTLC-based metabolomics approach can be a very reliable technique for the detection of chokeberry adulteration.

AB  - A. ursinum and poisonous adulterants C. majalis and A. maculatum were used as a model for detection of adulterants in edible plant. A. Ursinum samples were spiked with C. Majalis and A. Maculatum to mimic adulteration. Metabolomic fingerprinting of all samples was performed using 1H NMR spectroscopy (1D zgpr pulse sequence), and the resulting data sets were subjected to multivariate data analysis. As a result of this analysis, signals of adulterants were extracted from the data, and the structures of biomarkers of adulteration from partially purified samples were elucidated using 2D NMR. Thus, isovitexin and vicenin II, azetidine-2-carboxylic acid, and trigonelline indicated adulteration of A. Ursinum samples with C. majalis. Isovitexin was also recognized to be an indicator of adulteration of A. Ursinum with A. maculatum. In conclusion, the case study of A. Ursinum suggested that plant metabolomics approach could be utilized for identification of low molecular weight biomarkers of adulteration in edible plants.

AB  - Introduction
Ramonda serbica and R. nathaliae are resurrection plants that have the remarkable ability to survive the complete desiccation of their vegetative organs (i.e. leaves, stem, roots) during periods of drought and rapidly revive when rewatered and rehydrated.

Objective
To investigate metabolic changes in R. serbica and R. nathaliae during their desiccation and recovery process

Methods
Proton nuclear magnetic resonance (1H-NMR) and gas chromatography–mass spectrometry (GC–MS)-based metabolomics approach coupled with multivariate data analysis was utilised to identify the metabolomes of the plants from 90 biological replicates.

Results
Sucrose and the polyphenolic glycoside myconoside were predominant in almost equal amounts in all samples studied, regardless of their water content at sampling. During the dehydration process, a decrease in the relative content of fructose, galactose, and galactinol was observed while the contents of those metabolites were preserved in the partially rehydrated plants. Raffinose and myo-inositol were accumulated in dry samples.

Conclusion
Using 1H-NMR and GC–MS as two complementary analytical platforms provided a more complete picture of the metabolite composition for investigation of the desiccation and recovery process in resurrection plants.

AB  - Schizophrenia is a widespread mental disorder that leads to significant functional impairments and premature death. The state of the art indicates gaps in the understanding and diagnosis of this disease, but also the need for personalized and precise approaches to patients through customized medical treatment and reliable monitoring of treatment response. In order to fulfill existing gaps, the establishment of a universal set of disorder biomarkers is a necessary step.
The investigation of serum samples of Serbian patients with schizophrenia (51) and healthy controls (39), based on NMR analyses based on detection and of low molecular weight components in samples can be difficult due to overlapping signal caused by line broadening characteristics of macromolecules. A way of overcoming this problem could be the exploitation of the difference in relaxation between small molecules and macromolecular species, such as the application of a T2 filter by using the Carr–Purcell–Meiboom–Gill (CPMG) spin-echo pulse sequence, which led to the identification of 26 metabolites/biomarkers for this disorder.
The established biomarker set includes aspartate/aspartic acid, lysine, 2-hydroxybutyric acid, and acylglycerols, which are identified for the first time in schizophrenia serum samples by NMR experiments. The other 22 identified metabolites in the Serbian samples are in accordance with the previously established NMR-based serum biomarker sets of Brazilian and/or Chinese patient samples. Thirteen metabolites (lactate/lactic acid, threonine, leucine, isoleucine, valine, glutamine, asparagine, alanine, gamma-aminobutyric acid, choline, glucose, glycine and tyrosine) that are common for three different ethnic and geographic origins (Serbia, Brazil and China) could be a good start point for the setup of a universal NMR serum biomarker set for schizophrenia.

experiments, the content of the two most dominant polar components found in the
leaves of these two plants was determined. Sucrose and the polyphenolic glycoside
myconoside were predominant in almost equal amounts in all samples studied,
regardless of their water content at sampling. Using of 1D and 2D NMR

AB  - Chokeberry is a plant belonging to the family Rosaceae which has a long history of edible and
medicinal use. The aims of this study are: i) to investigate of HPTLC profile of berries samples
using HPTLC technique based metabolomics approach, ii) to determine the botanical origin of
investigated chokeberry adulterations iii) to identify the most important botanical markers
responsible for classification.
A simple, rapid, and high-throughput planar chromatography (HPTLC) method was applied in
combination with multivariate techniques for differentiating chokeberry samples and identification
of the main metabolites of chokeberry and four common adulterants. Images of HPTLC
chromatograms obtained using two different detections i.e. visible light and derivatization with
natural products reagent were used as a dataset for multivariate analysis.
Principal component analysis and Orthogonal Partial Least Squares Discriminant Analysis
confirmed the discrimination of five botanically different samples and recognized their main
markers such as responsible for differences between chokeberry and four common adulterants.
The obtained results showed that the HPTLC-based metabolomics approach can be a very reliable technique for the detection of chokeberry adulteration

AB  - The objective of this study was to test four-dimensional LC-ESI-MS/MS chromatography in analysis of complex mixture such as ethanol extracts of different propolis samples. In total more than 1200 picks were identified and only for 185 literature conformation was found. The given data represent the result of tentative identification, and summarized results are given in the text. Comparing the samples, from different altitudes, 96 components were detected as characteristic in high altitude samples and 18 in samples collected at low altitudes. Antimicrobial activity of ethanol extracts of propolis (EEP) and pro­pyl­ene glycol extracts of propolis (PGEP) were carried out on S. aureus, B. cereus, M. flavus, L. monocytogenes, P. aeruginosa, S. typhimurium, E. coli and E. cloacae bacterial strains and compared with broad-spectrum antibiotics, streptomycin and ampicillin. Anti-quorum sensing activity was performed on P. aeruginosa by testing the effect of representative propolis extracts on bio­film formation, twitching and motility activity and production of pyocyanin. We demonstrated that the majority of explored propolis extracts have greater or equal minimal inhibitory concentration and minimum bactericidal concen­tra­tion values compared to antibiotics, independently of the solvent used for the extraction. The samples collected from the highest altitude emerged as least active antimicrobial agents but with the greatest potential as anti-quorum sen­sing agents.

AB  - Chamomile (Matricaria chamomilla L., Asteraceae) is one of the most popular medicinal plants used as a herb
infusion for treating numerous ailments, including sleep disorders, anxiety, digestion and intestinal conditions
etc. Chamomile essential oil is used in a wide variety of consumer goods such as detergents, soaps, toiletries,
cosmetics, pharmaceuticals, perfumes, confectionery food products, soft drinks, distilled alcoholic beverages
(hard liquor) and as insecticide. According to the European Pharmacopoeia, there are two types of essential
oils, one rich in bisabolol oxides and the other in α-bisabolol, which are preferred for tea brewing because of
its sweet, grassy, and slightly fruity aroma. From the other side, varieties rich in chamazulene and β-farnesene
have bitter taste, and because of that they are low valuable raw material. According to the results of the
essential oil composition obtained from three different chamomile samples grown in Province of Vojvodina, it
could be concluded that domestic cultivars “Banatska” and “Tetraploidna” contains β-farnesene as dominant
compound, while the content of bisabolol oxides and α-bisabolol was lower than required standards in
European Pharmacopoeia. Because of that they could not be classified as quality raw material. The German
cultivar “Mabamille” grown in agroecological conditions of Vojvodina region, with 37.5% of α-bisabolol can be
classified as a bisabolol rich type, and as high quality row material.
AB  - Kamilica (Matricaria chamomilla L., Asteraceae) je jedna od najpopularnijih lekovitih biljaka koja se 
upotrebljava u obliku infuza (čaja) za lečenje mnogih stanja i bolesti, uključujući poremećaje sna, napetost, probleme organa za varenje itd. Etarsko ulje kamilice se koristi u mnogim granama industrije: hemijskoj (kao dodatak deterdžentima), kozmetičkoj (u sapunima, sredstvima za ličnu higijenu), farmaceutskoj, parfimerijskoj i prehrambenoj industriji (u slatkišima, alkoholnim i bezalkoholnim pićima) i kao insekticid. Prema Evropskoj Farmakopeji, postoje dva tipa etarskog ulja kamilice, prvi koji je bogat bisabolol oksidima i drugi bogat α-bisabololom. Oba tipa su poželjna u industriji čajnih napitaka zbog njihovog slatkog, osvežavajućeg ukusa blago voćne arome. Sa druge strane, varijeteti bogati hamazulenom i β-farnezenom imaju gorak ukus i zbog toga predstavljaju manje vrednu biljnu sirovinu. Na osnovu rezultata hemijskog sastava etarskog ulja tri 
različita uzorka kamilice gajene u Pokrajini Vojvodini od strane individualnih poljoprivrednih proizvođača, može se zaključiti da domaće sorte “Banatska” i “Tetraploidna” sadrže β-farnezen kao dominantnu komponentu, dok je sadržaj bisabolol oksida i α-bisabolola niži nego što zahtevaju standardi u Evropskoj Farmakopeji, zbog čega se ne mogu kategorisati kao kvalitetni biljni materijal. Nemačka sorta “Mabamille” gajena u agroekološkim uslovima pokrajine Vojvodine, sa 37,5% α-bisabolola pripada bisabolol tipu kamilice i predstavlja visoko kvalitetnu sirovinu.

AB  - Oregano is one of the most used culinary herb and it is often adult­erated with cheaper plants. In this study, GC–MS was used for identification and quan­tification of metabolites from 104 samples of oregano (Origanum vul­gare and O. onites) adulterated with olive (Olea europaea), venetian sumac (Cotinus coggy­gria) and myrtle (Myrtus communis) leaves, at five different concentration levels. The metabolomics profiles obtained after the two-step derivatization, involving methoxyamination and silanization, were subjected to multivariate data analysis to reveal markers of adulteration and to build the reg­ression models on the basis of the oregano-to-adulterants mixing ratio. Ortho­gonal partial least squares enabled detection of oregano adulterations with olive, Venetian sumac and myrtle leaves. Sorbitol levels distinguished oregano samples adulterated with olive leaves, while shikimic and quinic acids were recognized as discrimination factor for adulteration of oregano with venetian sumac. Fructose and quinic acid levels correlated with oregano adulteration with myrtle. Orthogonal partial least squares discriminant analysis enabled dis­crimination of O. vulgare and O. onites samples, where catechollactate was found to be discriminating metabolite.
AB  - Оригано је једна од најчешће коришћених кулинарских биљака и често се криво- твори јефтинијим биљкама. У овој студији, гаснa хроматографијa–масенa спектро- метријa коришћена је за идентификацију и квантификацију метаболита из 104 узорка оригана (Origanum vulgare и O. onites) кривотвореног маслином (Olea europea), венеци- јанским сумаком (Cotinus coggygria) и миртом (Myrtus communis), у пет различитих концентрација. Метаболомички профили добијени након двостепене дериватизације, која укључује метоксиаминовање и силанизацију, подвргнути су мултиваријантној ана- лизи података како би се открили маркери кривотворења и направили регресиони модели на основу односа мешања оригана и биљака за кривотворење. Ортогонална дели- мична анализа најмањих квадрата је омогућила детекцију кривотворења оригана лишћем маслине, венецијанског сумака и мирте. Садржај сорбитола разликовао је узорке оригана кривотворених лишћем маслине, док су шикиминска и кининска кисе- лина препознате као фактор разликовања за кривотворење оригана венецијанским сумаком. Садржај фруктозе и кининске киселине у корелацији су са кривотворењем оригана миртом. Ортогонална делимична анализа најмањих квадрата – дискриминантна анализа је омогућила разликовање узорака O. vulgare и O. onites, при чему је одређено да је катехоллактат метаболит који разликује ове две биљне врсте.

AB  - Plum brandy (Slivovitz (en); Šljivovica(sr)) is an alcoholic beverage that is increasingly consumed all over the world. Its quality assessment has become of great importance. In our study, the main volatiles and aroma compounds of 108 non-aged plum brandies originating from three plum cultivars, and fermented using different conditions, were investigated. The chemical profiles obtained after two-step GC-FID-MS analysis were subjected to multivariate data analysis to reveal the peculiarity in different cultivars and fermentation process. Correlation of plum brandy chemical composition with its sensory characteristics obtained by expert commission was also performed. The utilization of PCA and OPLS-DA multivariate analysis methods on GC-FID-MS, enabled discrimination of brandy samples based on differences in plum varieties, pH of plum mash, and addition of selected yeast or enzymes during fermentation. The correlation of brandy GC-FID-MS profiles with their sensory properties was achieved by OPLS multivariate analysis. Proposed workflow confirmed the potential of GC-FID-MS in combination with multivariate data analysis that can be applied to assess the plum brandy quality.

from the n-butanol extract of the salt marsh plant Atriplex tatarica. In addition, two known secondary
metabolites, patuletin 3-O-β-D-apiofuranosyl-(1‴→2″)-β-D-glucopyranoside (5) and patuletin 3-O-5‴-Oferuloyl-β-D-apiofuranosyl-(1‴→2″)-β-D-glucopyranoside (6), were isolated for the first time from A. tatarica.
The structures of the isolated compounds were elucidated by 1D and 2D NMR, HRESIMS, IR, and UV data.
Antibacterial activity by the microdilution method and antibiofilm activity against P. aeruginosa were assessed.
The best activity against Micrococcus flavus and Pseudomonas aeruginosa showed compound 1, while against
Listeria monocytogenes and Escherichia coli the strongest activity was shown by compound 5. Isolated
saponins (2-4) exhibited a more pronounced biofilm inhibition activity than flavonoid glycosides (1, 5-6). The
best anti-biofilm activity showed compound 2.

AB  - FTIR spectroscopy is non-destructive and simple analytical technique that requires
small sample amounts for providing information about functional groups in molecules. In
certain cases, it is indispensable for structure elucidation of complex organic molecules such as
triterpene derivatives1. Applying this technique, it is possible to monitor the change in the
secondary structure of the protein.2.
Combined with various statistical methods it is a powerful analytical tool in
metabolomics. Thus, FTIR data based statistical models enabled propolis classification and
floral origin determination3. In combination with biological tests such as cytotoxic activity), it
can be used for biologically guided isolation of active compounds4.
Nowadays FTIR spectroscopy is being routinely used for solving various practical
analytical problems, e. g. quality analysis of bees products (beeswax and honey), quantitative
determination of the major constituents in most types of food and agricultural products,
straightforward identification of kidney and bladder stones etc.

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 antimicrobial activity of methanol extracts of three thalloid liver­worts, Marchantia polymorpha, Conocephalum conicum and Pellia endiviifolia and bis-bibenzyl marchantin A, the most dominant compound in the methanol extract of M. polymorpha, have been investigated in this research. 1H-NMR spec­troscopy revealed that the M. polymorpha and P. endiviifolia extracts of liverwort contain terpenes, oils, sugars and bis-bibenzyls, while these specific macrocyclic compounds were absent in the C. conicum extract. The anti­mic­robial potential was tested on eight bacterial strains. Antimicrobial effects of extracts and mar­chantin A were observed against Gram-positive bacteria, while they showed no effect against Gram-negative bacteria in both methods used – well diffusion and broth microdilution.

AB  - Metabolomics has emerged in recent years as an indispensable tool for the analysis of thousands
of metabolites from crude natural extracts, leading to a paradigm shift in natural products drug
research. Many of the technologies used in metabolomics have method-specific advantages and
drawbacks in terms of diversity of metabolites detected, sensitivity, or resolution.
We will describe the use of metabolomic methods for:
• Correlation of propolis composition to altitude of collection and revealing its major botanical
origin.
• revealing cytotoxic metabolites from Mahonia aquifolium stem-bark
• application for differentiation of the ambiguous taxonomy of the genus Amphoricarpos Vis.
In order to correlate variability in Populus type propolis composition with the altitude of its
collection, NMR spectroscopy followed by OPLS was conducted. The botanical origin of propolis
was established by comparing propolis spectral data to those of buds of various Populus species.
An O2PLS method was utilized to integrate two blocks of data. The utilization of various NMR
experiments, in combination with sophisticated multivariate analysis methods, was demonstrated
to be a powerful tool to correlate propolis composition to altitude of collection and reveal its major
botanical origin. OPLS methods were used to identify changes in the chemical composition of
propolis, while O2PLS methods enabled the identification of the botanical origin of propolis.[1]
A 1H NMR-based metabolomics method was used to reveal cytotoxic metabolites from Mahonia
aquifolium stem-bark. Primary and secondary metabolites in the Mahonia aquifolium extracts
were identified by thorough analysis of 1H and 2D NMR spectra, without prior isolation. An OPLS
multivariate analysis method was used to correlate the chemical composition of the plant extracts
with the results of cytotoxic activity against Human cervical adenocarcinoma cell line.[2]
Metabolomic methods were used to get more insight into the ambiguous taxonomy of the genus
Amphoricarpos Vis. The 1H NMR spectroscopy combined with multivariate data analysis has been
applied. OPLS-DA has been shown to be the best method for clear discrimination of these samples
based on the metabolites present in the extracts. 1H NMR fingerprinting in combination with PCA
and OPLS-DA showed a clear separation between the species resulting in two groups according to
metabolomic similarities.

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 Trametes versicolor laccase catalyzed oxidation of chalcone butein afforded four dimers of aurone sulfuretin (i.e. two regioisomeric pairs of diasteromers, 1-4) as the major products. The formation of the dimers was explained by a two step process involving the initial cyclization of butein into aurone sulfuretin, followed by the combination of two molecules of sulfuretin. The coupling process occurred between the 2,10-double bond of one molecule of sulfuretin and the (3′,4′) catechol group of the other to yield a dimeric structure. This was confirmed by the experiment involving the laccase catalyzed oxidation of sulfuretin yielding the same dimeric bisaurones. Compounds 1, 3 and 4, were isolated using semipreparative HPLC and characterized by the detailed analysis of the NMR, MS, IR, and UV-vis data. The structure of compound 2, isolated as a mixture containing ca. 25% of compound 1, was proposed by the comparison of 1H NMR data to compound 1 and by using LC-ESIMS analysis. The starting chalcone butein and the products of the biocatalytic transformation, aurone sulfuretin and sulfuretin dimers 1, 3 and 4, were evaluated for their cytotoxic and antioxidative properties in vitro using a healthy human fibroblast (MRC5) cell line. The biotransformation products showed lower cytotoxicity but higher antioxidative properties. The C. coggygria bark methanol extract rich in butein and sulfuretin was also biotransformed by laccase. The transformed extract exhibited significantly improved antioxidative activities.

AB  - The present study evaluates natural composition of Serbian roasted hazelnut skins (HS) with potential role in application as functional nutrient of various food products. Total phenols (TPC) and flavonoids contents (TFC) in HS extracts obtained with different ethanol concentrations (10%—I, 50%—II and 96%—III) and their antioxidant activities were investigated. The highest total phenols content (706.0 ± 9.7 mgGAE/gextract) was observed in 96% ethanol HS extract. Ethanol HS extracts showed very high antioxidant activity with effective concentrations (EC50) ranged between 0.052 and 0.066 mg/mL. The phenol and flavonoid content of roasted HS extracts I–III was determined by HPLC-ESI-MS/MS analyses. Contents of lipids, proteins, carbohydrates, metals, and C, H, N, S elements in roasted HS were also determined. Relatively high C/N, C/P and C/N/P ratios, rich metal contents and fatty acids composition indicated that hazelnut skin might be a good candidate for use as either human or fungal functional nutrient. In addition, possible application of phenolic HS extracts as UV booster was studied by recording UV spectra (220–440 nm) of 10 mg/L of HS extracts I–III combined with 10 mg/L of chemical sunscreen agent benzophenone-3 and in vitro sun protection factor (SPF) was calculated.

AB  - Schizophrenia (SCZ) is a very disabling mental disorder whose molecular basis is a combination of many factors still not completely understood, with a diagnosis based on observed behavior, the person's reported experiences and reports of others that are familiar with the person, with no objective test. Also, up to date, there are no reliable markers for monitoring the SCZ. NMR-metabolomics [1] reported in 2017 bring some of the possible markers from blood serum of SCZ individuals linked strongly with known dopamine, glutamate and GABA dysfunction in SCZ. As to verify if these findings are universal, we have compared the SCZ patients from geographically different environments and cited interesting SCZ characteristics.  
The first set of samples was collected in Belgrade, Serbia. 14 mental health patients (50% male) with 52.86 ± 7.27 years of age had a confirmed diagnosis of SCZ. The control group of 13 healthy individuals (69% male) had none of psychotic disorders, and individuals were 23.07 ± 2.79 years of age. Blood serum samples were collected and prepared for the analysis following the published methodology [1, 2]. NMR spectra were measured on a Bruker AVANCE III spectrometer (500.26 MHz for 1H). The spectra were acquired at 298 K with 128 scans and 32 k. The serum samples were prepared and measured as triplicates.  
On the other side, the group of individuals from Brazil that was matched in number, age, gender and history of mental illness with individuals from Serbia was previously described [1].  
1H NMR spectra were phase and baseline corrected using MestreNova and the lactate doublet was used as the chemical shift reference. The data were binned (0.005 ppm) in a spectral range 0.50 - 9.00 ppm, while the residual HDO peak (4.50-5.00 ppm) was excluded. Then, the data were normalized by the sum equal to 1000, the variables were mean centered and PCA and PLS-DA were performed using MATLAB.  
It was shown that the mental health patients have clearly different blood serum metabolites when compared to the healthy ones independently from where the samples were obtained with almost identical marker set. Also, it was shown that the samples are different metabolically when Brazilian and Serbian samples were compared.

AB  - Ramonda serbica represents the remnant of the Tertiary tropical and subtropical flora in Europe and is the rare resurrection plants of Northern Hemisphere temperate zone. The plant remains well-hydrated during spring, late autumn and in winter. In summer and early autumn when plants are subjected to drought, their desiccation tolerance comes into operation and they spend it in anabiosis [1]. In this study, metabolic responses to dehydration and rehydration of R. serbica, were investigated. For this purpose, GC-MS/FID
based metabolomics method was performed. Leaves from the control (well-watered), dehydrated and partially rehydrated plants were sampled. Each leaf was powdered using liquid nitrogen and then freeze-dried. The internal standard (10-undecenoic acid) was added to the dry plant material and then extracted in methanol/water using ultra-sonication. After centrifugation of the mixture, the supernatant was dried and derivatized using two-step procedure involving oximation and silylation. GC-MS/FID analysis of each sample was then performed. The metabolites were identified using El-MS spectra. The areas from FID chromatograms were used for multivariate data analysis. Two OPLS-DA models were applied to investigate dehydration and rehydration process. According to high VIP scores, sugars, such as fructose, glucose, galactinol, sucrose, together with glyceric acid, xylonic acid 8-lactone and aspartic acid were found to be the most influential in the OPLS-DA models.

Two OPLS-DA models were applied to investigate dehydration and rehydration process. According to high VIP scores, sugars, such as fructose, glucose, galactinol, sucrose, together with glyceric acid, xylonic acid 8-lactone and aspartic acid were found to be the most influential in the OPLS-DA models.",
