This paper presents the results of an experimental study of the component composition of essential oil samples obtained from various vegetable raw materials of Schisandra chinensis (Schisandra chinensis (Turcz.) Baill.): branches (woody stems), rhizomes with roots and leaves. The extraction of essential oils was carried out by distillation with water vapor followed by extraction from the distillate with ethoxyethane. The largest yield of essential oil in terms of completely dry raw material is registered from rhizomes with roots – 0.99%; the yield from leaves and branches was approximately the same: 0.51% and 0.52%, respectively. A comparative analysis of the component composition of the obtained essential oils was carried out using the gas chromatography / mass spectrometry method. In the essential oil of the leaves 29 detected compounds (identified by 21 connection; dominant components: Cyclohexylmethyl ether sulphurous acid, (+)-trans-nerolidol, δ-cadinene, Tridec-(2E)-EN-1-ol), woody stems 80 connections (identified 65 compounds; dominant components: ß-pinene, Camphene, Bornylacetate, (+)-trans-nerolidol, p-tsimen, Tridecan-2-it, δ-cadinene), rhizomes with roots 78 of the compounds (60 compounds identified; dominant components: δ-cadinene, Bornylacetate, β-pinene, Camphene, Nerolidol-(E), Tridecan-2-it, γ-cadinene, Borneol). For each sample of the studied essential oils selectivity and marker substances were established.

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

The objective of the work was to identify changes in the amount and component composition of essential oil in the raw material of Thymus vulgaris L. (common thyme) when using different distillation methods. The object of the study was two samples of thyme-thymol and linalool chemotypes. Essential oil was obtained from freshly harvested raw materials (inflorescences in the mass flowering phase) by the following methods: hydrodistillation method on Clevenger apparatuses and steam extraction method on the installation for the production of essential oil and intermediates "Alpha-Ether Compact". The component composition of volatile substances was determined by gas chromatography-mass spectrometry. In the composition of volatile compounds of plant essential oil, 29 components for the thymol chemotype were identified, and 18 components for the linalool chemotype were identified. It was found that the use of the hydrodistillation method allows extracting 40-50% more essential oil. Significant differences were found between the mass fraction of extracted essential oil components using different methods and the content of the mass fraction of essential oil in the raw material of Th. vulgaris and found that depending on the method of obtaining essential oil, the proportion of volatile terpene hydrocarbons and oxygen-containing compounds changes. The method of steam distillation leads to a deterioration of the component composition of the essential oil, reducing the content of the dominant components of both chemotypes (thymol and linalool).

Gas chromatography (GC) and gas chromatography–mass spectrometry (GC–MS) were used to compare between the essential oil components from needles of Pinus armandii Franch versus P. tabulaeformis Carr., growing on the same site at Taibai Mountain, China. Under optimum extraction and analysis conditions, 65 and 66 constituents each were identified in P. armandii and P. tabulaeformis, which accounted for 87.9% and 87.1%, respectively, of their oils. Based on their terpene compositions, we concluded that these species belong to a high-caryophyllene chemotype, with sesquiterpenes comprising 54.4% to 54.8% of the total contents. We also determined minor qualitative and major quantitative variations in some compounds. Compared with that from P. tabulaeformis, P. armandii oil had more γ-muurolene (7.5%), terpinolene (5.8%), and longifolene (5.7%). In contrast, α-pinene (8.6%) and caryophyllene oxide (7.4%) were the dominant compounds in P. tabulaeformis.

Methods of essential oil steam distillation, capillary gas chromatography and statistical analysis were used in the research. It is established that increase in essential oil quantity was observed for peppermint breeds on which reproduction and improvement іn vіtro technology was applied. As a result of clonal microreproduction of peppermint plants in culture іn vіtro on nutrient medium Murasige and Skug, in which the growth regulators 0.75 mg/l of 6-benzylaminopurine, 0.1 mg/l of adenine, 0.05 mg/l of indolil-3-acetic acid and 0.5 mg/l of gibberellins acid were added and virocide Ribavirin in concentration 10 mg/l, improvement was obtained in comparison with vegetatively reproduced plants; increase in essential oil quantity per hectare was established for the following breeds; Chornolista by 54.2%, Lebedinaya pesnya by 38.2%, Ukrainskaya Perechnaya by 36.7%, Mama by 28.5%, Lubenchanka by 17.1% and Lidiya by 11.6%. For oil content the highest indices were noted for Lubenchanka, Mama and Lebedinaya Pesnya peppermint breeds with product yield 4.02%, 3.98% and 3.84% respectively. It was established that the essential oil component composition in non-clonal peppermint plants raw materials and plants-regenerants after culture in vitro is variable depending on breed. Limonene, cineole, menthone, menthofuran, iso-menthone, menthyl acetate, β-caryophyllene, iso-menthol, menthol, pulegone, germacren, piperitone, carvone were identified in peppermint essential oil. High content of menthol, low content of carvone, piperitone, pulegone (except for Chornolista, Ukrainskaya Perechnaya breeds) and menthofuran (except for Chornolista, Ukrainskaya Perechnaya and Lubenchanka breeds) are characteristic for Ukrainian selection peppermint investigated breeds. A clear tendency to menthol and menthone content ratio increase is observed in plants which were improved in conditions іn vіtro. Pulegone was not detected in essential oil samples of Lebedinaya Pesnya, Lidiya and Mama breeds. Biochemical markers of Lebedinaya Pesnya, Lubenchanka, Mama breeds, which differentiate them within the group of investigated breeds, are higher limonene, piperitone and menthol pool; for Ukrainskaya Perechnaya and Chornolista breeds – pulegone, cineole and menthone; for Lidiya breed – iso-menthone.

Abstract —The compositions of volatile components in cordierite, tourmaline, and quartz from pegmatites of the Kuhilal deposit were studied by pyrolysis-free gas chromatography–mass spectrometry (GC–MS), IR and Raman spectroscopy, and microthermometry, and their comparative analysis was performed. Capillary GC–MS was applied to determine the component composition and relative contents (rel.%) of volatiles from different zones of crystals and fractions of cordierite. It has been established that water and carbon dioxide prevail among them. Among hydrocarbons, aliphatic, cyclic, and oxygenated ones are predominant. Heterocyclic, nitrogenated, and sulfonated compounds have also been found. In tourmaline and quartz, volatile components are present in gas–liquid inclusions; in cordierites, they are localized both in structural cavities and in nonstructural positions.

Исследованы количественные и качественные изменения эфирного масла из травянистого сырья петрушки огородной (Petroselinum sativum) в фазе технической спелости растения – в период от молочной до молочно-восковой спелости плодов центральных зонтиков. Установлено, что выход эфирного масла увеличен на 50%. Определено, что прирост общего содержания эфирного масла влечет увеличение выхода большинства его компонентов. Наибольший прирост наблюдается для апиола (300%), массовая доля которого достигает 7,8%, что необходимо учитывать при организации уборки и в технологии переработки травянистого сырья P. sativum. Также существенно возрастает содержание в масле 1,3,8-пара-ментатриена – до 28,30%, обусловливающего аромат зелени петрушки. Более 70% общего количества компонентов масла составляют углеводороды и среди них, помимо 1,3,8-пара-ментатриена, альфа- и бета-пинены, лимонен. Рекомендовано проводить уборку травянистого сырья петрушки на стадии молочно-восковой спелости плодов центральных зонтиков. Доказана целесообразность дальнейших исследований содержания эфирного масла в различных органах растения на разных этапах фазы технической спелости для более полной характеристики количественных и качественных изменений и разработки технологии комплексной переработки травянистого сырья петрушки. The study of quantitative and qualitative changes of parsley essential oil Petroselinum sativum based on herbal raw materials in a phase of the technical ripeness of a plant – in the period from milk-ripe stage to milky-waxy stage of fruit ripeness of central parsley umbels allowed us to find out that at this stage the output of essential oils grows by 50%. There has been a steady increase in the total content of essential oils which leads to the increase in the output of most of its components. The biggest growth is observed for parsley camphor (300%), which mass fraction is 7,8%. It is necessary to take this fact into consideration during the harvest season and in the processing of parsley herbal raw materials P. sativum. It should be mentioned that hydrocarbons constitute 70% from the total amount of essential oil components, among them are 1,3,8-p-menthatriene, as well as alpha- and beta-pinenes, limonene. On the base of carried out research it is recommended to harvest parsley herbal raw materials at the milky-waxy stage of fruit ripeness of central parsley umbels. It is expedient to study changes in essential oils of various plants’ organs at various stages of technical ripeness for more complete characteristics of qualitative and quantitative changes and the development of complex technology of processing of parsley herbal raw materials.
