Essential oil from the roots of calamus marsh (Acorus calamus L) was isolated by the method of exhaustive hydroparodistillation, growing on the Krasnoyarsk territory. Separate fractions of essential oil were obtained depending on the duration of isolation. The component composition of the essential oil, the main components of which are acorenone, butyrate α-terpineol, germacrene B, camphor. The antiradical properties of the essential oil of A. сalamus roots growing in the Siberian region, as well as the antiradical properties of its individual fractions were studied for the first time in order to determine the most promising samples as sources of biologically active complexes. To determine the antiradical activity, the reaction of the essential oil components with a stable free 2,2-diphenyl-1-picrylhydrazyl radical was used. The antiradical activity of all studied samples of essential oils was established. There was an increase in antiradical activity with a decrease in the content of monoterpenes in the composition of the essential oil. The lowest antiradical activity (17.5%) was shown by the fraction of essential oil with a high content of monoterpenes, the highest (~100%) – fractions with a high content of oxygen-containing compounds. It was revealed that the ability of components of individual fractions of A. сalamus essential oil to inhibit DPPH radicals is comparable with the antiradical activity of ascorbic acid solutions of equivalent concentration.

Ulomoides dermestoides are used as a broad-spectrum medical insect in the alternative treatment of various diseases. Preliminary volatilome studies carried out to date have shown, as the main components, methyl-1,4-benzoquinone, ethyl-1,4-benzoquinone, 1-tridecene, 1-pentadecene, and limonene. This work focused on the production of metabolites and their metabolic variations in U. dermestoides under stress conditions to provide additional valuable information to help better understand the broad-spectrum medical uses. To this end, VOCs were characterized by HS-SPME with PEG and CAR/PDMS fibers, and the first reported insect essential oils were obtained. In HS-SMPE, we found 17 terpenes, six quinones, five alkenes, and four aromatic compounds; in the essential oils, 53 terpenes, 54 carboxylic acids and derivatives, three alkynes, 12 alkenes (1-Pentadecene, EOT1: 77.6% and EOT2: 57.9%), 28 alkanes, nine alkyl disulfides, three aromatic compounds, 19 alcohols, three quinones, and 12 aldehydes were identified. Between both study approaches, a total of 171 secondary metabolites were identified with no previous report for U. dermestoides. A considerable number of the identified metabolites showed previous studies of the activity of pharmacological interest. Therefore, considering the wide variety of activities reported for these metabolites, this work allows a broader vision of the therapeutic potential of U. dermestoides in traditional medicine.

Abstract Background: Phoebe bournei is a potential medicinal plant whose essential oil (EO) from leaves has potential inhibitory activities against some bacterium, tumor, and has a certain potential for hypoglycemic activity. Fertilization is a common and effective method to increase plant biomass, which can increase the raw material of essential oil, but has a certain impact on the composition and biological activity of plant essential oil. Results: The main components are sesquiterpenes in the essential oils from leaves and twigs. The yield of the essential oils and the content of their main components can be modulated by compost and compound fertilizer, to different degrees, and minor differences were registered among the categories of the components in essential oils. However, changes were strongly mirrored in some main components of essential oils. The content of the primary (+) - calarene in the leaf EO were strongly increased by compost, but the opposite happened by compound fertilizer. On the contrary, the effect of compound fertilizer was more significant on the main components of twig essential oil than compost. The transcriptome sequencing results of P. bournei showed that the total number of DEGs in twigs and leaves treated with compost were significantly more than that with compound fertilizer. No change was found in the expression of genes regulating principal components. However, the expression of several key genes regulating the upstream substrates for the synthesis of the sesquiterpenes was significantly changed: the expression of two key speed limiting enzymes genes (DXS and HMGR) and two important branch-point enzyme genes (FPPS and GGPPS) was significantly down regulated, while the expression of gene (HMGS) was significantly up-regulated.Conclusion: The expression levels of genes (DXS2, HMGR, FPPS and GGPPS) were significantly down regulated in leaves treated with compost, resulting in the changes of the yield and main components of the leaf essential oil. The effect of compost was more significant on the synthesis of the essential oil from P. bournei leaves than that of compound fertilizer.

The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of Thymus serpyllum and Thymus serpyllum‘Aureus’ has been investigated by gas chromatography-mass spectrometry (GC-MS). Forty-seven compounds (99.67% of the total oil) wereidentified in the essential oil of T. serpyllum. The main components found in the oil were carvacrol (37.49%), -terpinene (10.79%), -caryophyllene (6.51%), p-cymene (6.06%), (E)--ocimene (4.63%) and -bisabolene (4.51%). Similarly, carvacrol (44.93%), -terpinene(10.08%), p-cymene (7.39%) and -caryophyllene (6.77%) dominated in the oil of T. serpyllum ‘Aureus’. A total of forty three compounds wereidentified in this oil, representing 99.49% of the total oil content. On the basis of the obtained data it was proved that the content of 1-octen-3-ol,eucalyptol, (Z)--ocimene, (E)--ocimene, -terpinene, carvacrol methyl ether, germacrene D and -bisabolene was significantly higher for T.serpyllum while T. serpyllum ‘Aureus’ was characterized by a significantly higher content of 3-octanone, 3-octanol, p-cymene, borneol andcarvacrol. The isolated essential oils were evaluated for their antimicrobial activity against nine reference strains (Escherichia coli, Staphylococcusaureus, Staphylococcus epidermidis, Streptococcus agalactiae, Enterococcus faecalis, Bacillus cereus, Micrococcus luteus, Proteus vulgaris and Candidaalbicans) by the microdilution technique. Based on this test, the minimum inhibitory concentrations (MIC) of essential oil were calculated. Thevolatile oil obtained from T. serpyllum showed the highest antimicrobial activity relative to the strain of E. coli (MIC=0.025 μL/mL) and to theyeast C. albicans (MIC=0.05 μL/mL). Similarly, a significant antimicrobial activity exhibited T. serpyllum ‘Aureus’ essential oil, although the MICvalues obtained in that case for E. coli and C. albicans strains were twice as high and were respectively 0.05 μL/mL and 0.1 μL/mL.

The aim of the research is to analyze the content of terpenes in the needles of trees of climatic ecotypes of Scots pine growing in geographic forest crops and to reveal the differences in the level of essential oils. The object of the research is 17 Scots pine climatypes growing in geographical plantations on the territory of the Negorelsk Educational and Experimental Forestry Enterprise of the Minsk region in Belarus. Qualitative and quantitative analysis of Scots pine needles essential oil was carried out by gas-liquid chromatography without preliminary fractionation on chromatograph "Kristall 5000.1". In the studied climatypes of Scots pine, different levels of essential oil content among monoterpenes, sesquiterpenes and oxygen-containing groups were determined, as well as significant differences in the content of a number of components within the studied groups were revealed. The highest yield of essential oil is observed in the subspecies of the European Western Scots pine - 1.9%, slightly lower than this indicator in the forest-steppe subspecies (1.7%). This indicator was significantly lower in the European Eastern pine variety - 1.1% and the Siberian subspecies - 1.0%. The obtained data on the composition of essential oil and the ratio of a number of components among subspecies and varieties of Scots pine (subspecies: Lapland, Siberian, forest-steppe, European; varieties: European western and eastern) will further select the most promising climatic ecotypes and subspecies for selection resistance to biotic and abiotic environmental factors, taking into account the growth and productivity of stands. Information on the content of essential oil components in the needles of climatypes and subspecies of Scots pine makes it possible to expand knowledge in the field of plant resistance, their safety and growth, especially in the context of the outlined climate change. Key words: component composition, extractives, monoterpenes, sesquiterpenes, diterpenes, geographical plantations, climatic ecotype.
