The article presents the results of determining the composition of essential oils of Prunus persica var. nectarina varieties "yellow nectarine" – "sariк luchchak (uzb.) ", growing in two regions of the Ferghana region of the Republic of Uzbekistan. The pale yellow essential oil was obtained by hydrodistillation from un-dried fresh leaves of plants. The oil composition was determined by chromatography-mass spectrometry on an Agilent 7890 AGC 6890 N gas chromotograph with a quadrupole mass spectrometer (Agilent 5975C inert MSD) as a detector on an HP-5 MS quartz capillary column. An essential oil of pale yellow color was isolated from the leaves of plants. In the composition of essential oils, 56 and 61 compounds were identified in the first and second samples, respectively, wich is 94.55 and 96.00% of the total components. The dominant components of the first saple are camphor bicyclic monoterpene ketones (24.21%), α-thujone (15.00%) and β-thujone (4.27%), aromatic aldehyde benzaldehyde (18.83%) and isobornoleol bicyclic monoterpene alcohol (6.17%). In the second sample, bicyclic monoterpenic ketones (camphor) (36.67%), α-thujone (21.81%) and β-thujone (7.06%) and bicyclic monoterpene alcohol isobornoleol (9.4%) predominate and monocyclic unsaturated monoterpene α-terpinene (2.18%). In both samples, (+)-2-bornanone (camphor) is predominant. The studied variety Prunus persica var. nectarina can serve as a raw material for the production of essential oil, the main components of which are camphor and isobornoleol.

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 aim of our work was to carry out a comparative analysis of the essential oils of shoots and leaves of Laurus nobilis L. Ukrainian flora and to determine the prospects for their use in pharmacy. Materials and methods. Raw materials for obtaining essential oil (shoots and leaves) of Laurus nobilis L. were harvested in November 2017 in the southern regions of Ukraine. By the method of chromatography-mass spectrometry using an Agilent Technology 6890N chromatograph, the component composition of 4 samples of essential oil of Laurus nobilis L. raw material was investigated and identified. The composition of the essential oil was identified by comparing the results with the data from the NIsT 02 mass spectra library (more than 174,000 substances). Results. Thus, in the studied series of the essential oil of the shoots, a similarity was observed both in the set of components and in the relative content of a number of individual compounds and compounds of structurally related groups. The content in these samples was dominated by 1,8-cineole (19.63 % of the amount and 12.93 % of the amount, respectively), α-terpinyl acetate (16.22 % of the amount and 16.03 % of the amount, respectively). In contrast to the series of the essential oil of the shoots, the component composition of the essential oil of the leaves of the two series was significantly different. In both studied series, only 3 compounds were identified that are common - these are aromatic compounds methyleugenol, trans-methylisoevgenol, and the sequiterpenoid caryophyllene oxide. Conclusions. Thus, a comparative analysis of the component composition of biologically active substances in the essential oils of shoots and leaves of the Laurus nobilis L. Ukrainian harvest showed the prospects for further pharmacognostic research of this plant as a source of medicinal raw materials
