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.

Abstract. The purpose of the study was to study the effect of various methods of cultivating the variety of common myrtle Yuzhnoberezhny on the change in the content of macro- and microelements in raw materials, to compare the component composition of the essential oil obtained in the long-term and overgrowth form of its cultivation. Myrtus communis L. is a representative of the Mediterranean plant community, which since ancient times has been used for medicinal purposes and as a spicy culture. In the Nikitsky Botanical Garden – the National Scientific Center of the Russian Academy of Sciences, a variety of common myrtle South Coast was created. The variety is recommended for industrial cultivation on the territory of the southern coast of Crimea. Methods. The mineral composition of the raw materials was determined by dry ashing of leaves cut in the phase of technological maturity. The content of seven essential elements was determined on the quantum 2MT atomic absorption spectrophotometer: potassium in the emission mode, calcium, magnesium, ferrum, manganese, cuprum and zinc in the absorption mode. The component composition was studied in samples of essential oil on an Agilent Technology 6890N chromatograph with a 5973N mass spectrograph detector. Results. The maximum yield of medicinal raw materials in these soil and climatic conditions was ensured sprout cultivation, in which the rate of shoot formation increased by 2.6 times, and the yield of leaf, which is the raw material for the essential oil and food industries, increased by 37 %. The method of cultivating myrtle influenced the content of essential elements in the raw materials: the growth of ferrum and zinc was facilitated by the overgrowth form of cultivation, and cuprum and manganese – by many years. The amount of ferrum in the phase of technological maturity of the leaf was 84.37 mg/kg: in leaf-growing leaves 2.67 times more than in raw materials with a long-term form of cultivation. For cuprum, the opposite tendency was obtained – during germination cultivation, its concentration decreased by 2 times. The culture and variety are characterized by a high amount of magnesium and calcium in the leaf mass, regardless of the method of cultivation, up to 3.3 times the daily requirement of a person. Scientific novelty. A distinctive feature of this culture and variety is its high manganese content (20.2 mg/kg) in comparison with other perennial crops growing in this area (Helichrysum, Lavandula, Elsholtzia).

Hyssopus officinalis L. is a promising essential oil plant of complex use containing various types of biologically active substances (BAS). The purpose of the research was twofold: study the features of accumulation of various types of BAS in H. officinalis plants grown in the foothill zone of the Crimea; assess the possibility to use them in perfumery, cosmetics, food industry, pharmacy and medicine. The research was conducted in 2017–2019 in the FSBSI “Research Institute of Agriculture of Crimea”. The raw materials of H. officinalis (population with blue flowers) grown without irrigation served as the research material. Qualitative and quantitative characteristics of raw materials and different types of BAS were determined according to generally accepted methods. Structural analysis of H. officinalis showed that the aboveground part of plants during the growing season had the following fractional composition: leaves (21.4–70.6 %), stems (18.8–30.9 %), inflorescences (22.0−59.1 %). The ratio of fractions by phases of vegetation varied, namely: in the phase of regrowth, leaves prevailed – 70.6 % but, at the end of the flowering, their content decreased to 21.4 %; the content of inflorescences reached its maximum in the phases of mass flowering and end of flowering 53.3–59.1 %. The main oil-synthesizing organs of H. officinalis were leaves and inflorescences. The highest yield amount of H. officinalis essential oil was obtained from inflorescences (1.94 %), which in the fractional composition of the raw material amounted to 53.3 %. The maximum amount of essential oil of specific quality accumulated in plants during the phase of mass flowering (1.26 % in terms of absolutely dry weight). The dominant components of essential oil are ketones: isopinocamphone and pinocamphone (75.9–78.6 %). A high level of phenolic compounds was determined in the phases of regrowth and flowering; extractive substances – in the budding phase; tannins – in the phase of mass flowering. During the storage of air-dry raw materials for two years, insignificant losses of essential oil occur (up to 20.2 %); its component composition changes (hydrocarbons amount decreased by 2.5–22.7 %; ketones – increased by 3.4–16.2 %). The content of other types of BAS during storage of raw materials increased by 10–30 %. Therefore, it is advisable to store air-dry raw materials of Hyssopus officinalis for two years or longer.

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.
