The qualitative and quantitative composition of two species of Oplopanax root was studied by gas chromatography with mass spectrometric detection. Extraction of components from the investigated objects was carried out by extraction of dry ground raw material with 70% ethanol. For the analysis of polar compounds, the extracts were further derivatized to give the corresponding trimethylsilyl derivatives. Identification of components was carried out using commercial (NIST17, Wiley14) and own custom mass-spectrometer libraries. The percentage of components found was calculated using the areas of the corresponding chromatographic peaks. Found in these samples were 130 compounds of various classes: terpenes and their derivatives, alcohols, aldehydes, polyyns, polyenes, various acids and their derivatives, phenols, sterols, lignans, vitamins, nucleosides, glycosides and sugars. It has been established that the qualitative and quantitative composition of root extracts varies even within the same species. The presence of 26 compounds common to the two species of Oplopanax, including 12 acids, 3 polyyns, 6 terpenes and one representative each from the class polyenes, aldehydes, lignans, glycosides and sterols, was revealed. As a result of the comparative analysis, it was established that 4 compounds from the class of polyyns (falcarindiol acetate, oplopanediol acetate, oplopantriol A and oplopantriol B) are found only in the roots of O. horridus.

The species of nettle (Urtica dioica) are used long ago as hemostaticum for hemorrhages of various genesis both in non-traditional and in official medicine. Besides, the extractions of nettle possess hypolipidemic, cholagogue, anti-inflammatory, spasmolytic, prostatoprotective, adaptogenic properties, etc. Biologic activity of the nettle (Urtica dioica) is conditioned by the presence of various vitamins, carotenoids, proteins, flavonoids, hydroxycinnamic and organic acids, β-cytosterol, volatile compounds and other components. The aim of our study was to investigate the qualitative and quantitative composition of the volatile content of nettle. The research has been done on aero-dried vegetable raw-material Urtica dioica L. (leaves), stocked in June 2014 in Zaporizhzhya region. Identification and assessment of a number for volatile components has been done on the chromatograph Agilent Technology 6890 N with mass-spectrometric detector 5973. Approximately 20 components have been revealed in the leaves of Urtica dioica: hexahydrofarnesilacetate (165,19 mc/kg) and squalene (99,59 mc/kg) are predominated. Phytol, 2-methoxy-4-vinylphenol, nonacosane, etc. are presented in lesser number. The content of chrysanthenone, p-cymen-8-ol, verbenone, nerolidol, caryophyllene oxide, tricosane, tetracosane, heptacosane and untriacontane was insignificant (1,9% of the total amount of volatile components). Total number of volatile components in the leaves of Urtica dioica was 498,61 mc/mg. The research of qualitative composition and a number of volatile components in the leaves of Urtica dioica growing in Ukraine demonstrate expediency to carry out the further researches on the species Urtica dioica for using them in elaborating phytodrugs of complex action.

Abstract The qualitative and quantitative determination of chlordane residues on raw agricultural products has been best achieved by gas chromatography techniques. While good recoveries (90–100% at the 0.1 ppm level) have been obtained from plant extracts with added standard chlordane, weathered chlordane residues show changes in number and size of gas chromatographic peaks. Chlordane at the 50 µg level, when exposed to the air at room temperature over a period of time, showed progressive decomposition and loss of the many components that make up chlordane.

First Time

Cytokinin-active compounds produced by marine bacteria have been conclusively detected for the first time. A bacterial strain isolated from marine sediment produced cytokinin-active compounds extracellularly during the logarithmic phase of growth. Taxonomical examinations showed that this bacterium belonged to the genus Vibrio. The cytokinins were identified and quantified as isopentenyladenine (0.28 μg/L) and isopentenyladenosine (0.14 μg/L) by gas chromatography -mass spectrometric analysis of their trimethylsilyl derivatives. Results of a plasmid survey suggests that genes specifying the cytokinin biosynthesis in this bacterium are located on the chromosome, not on a plasmid.

The qualitative and quantitative composition of four types of cinnamon bark (Cinnamomum) was studied by gas chromatography with mass spectrometric detection.Found in these samples were 72 compounds of various classes, including terpenes, aldehydes, alcohols, organic acids, coumarins, esters, catechins, vitamins, sterols, and sugars. As a result of the comparative analysis, the specific compounds were found that are characteristic for Cinnamomum zeylanicum (3-tuyen, 4 (10) -tuyen, eugenol, (-)-α-curcumen, linolenic acid and for a group of Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia, namely, sativene, isosativene, longicyclene, β-elemen, γ-mourolen, α-mourolen, α-calacorene, syrinaldehyde, and syringol. The presence of common compounds with certain concentration variability was revealed for all four types of cinnamon. The selection of the most informative compounds allowing species differentiation of the cinnamon bark has been carried out by the method of main components. Among these, four components (eugenol, α-mourolen, syrinaldehyde and linolenic acid) and specific and 12 components, such as cinnamic aldehyde, α-fellandrene, limonene, linalool, copaene, caryophyllene, coumarin, benzyl benzoate, cinnamic acid, palmitic acid, linoleic acid, and disaccharides, have common origin. Further research will be directed toward establishing the criteria that would allow species differentiation of the cinnamon bark of Cinnamomum zeylanicum, Cinnamomum burmannii, Cinnamomum loureiroi and Cinnamomum Cassia types.

The studies was defined qualitative and quantitative composition of flavonoids in lichen species Physcia stellaris (L.) Nyl., Collected in habitats with different levels of anthropogenic load. Changes in the composition of flavonoids is considered in the literature as an indicator of the direction of the synthesis of secondary metabolites by plants to protect against adverse environmental influences. It was found that the most diverse number of members (128 compounds), phenolic substances found in the least contaminated RB Ishimbai area and the fewest (58 compounds) was detected in Sterlitamak. Analysis of qualitative and quantitative composition of flavonoids showed that in the area of Ishimbaisky samples were found to accumulate naringin, dihydroquercetin, quercetin. The samples obtained in Alsheyevsky District noted in content highs routine, but samples Sterlitamak – fizetina and naringenin. The calculation of the potential antioxidant status showed that the samples of Ishimbaisky district formed the highest level of protection phenolic substances. It showed no direct correlation between the growth response to environmental pollution and the level of flavonoid content in the thallus of lichens.
