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  - 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  - 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.

abstract = "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  - 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.
