Hyssopus Officinalis

The steam distillation method was used to obtain samples of essential oil of plants of three varieties Hyssopus officinalis L., cultivated in the conditions of the Republic of Belarus. More than 20 components were identified and determined in the essential oils of plants of the varieties Lazurit, Rozotsvetkovy, Zaveya by gas-liquid chromatography. It has been established that the studied varieties of Hyssopus officinalis belong to the pinocamphone chemotype. The main components are pinocamphone (67.6–76.0%), β-pinene, eugenol, limonene, camphene, sabinene, linalool, 1,8-cineole, α-terpineol, α-pinene, γ-terpinene and pinocampheol. The distribution of the enantiomers of a-and b-pinenes, camphene, limonene and linalool was established in the studied samples. Antimicrobial activity of essential oils and optical isomers of pure β-pinene was investigated on Staphylococcus aureus, Salmonella alony, Bacillus subtilis, Clostridium sp., Escherichia coli Hfr H, Pseudomonas aeruosa by disc method. It is shown that (+)-β-pinene showed higher antibacterial activity to (-)-β-pinene. The increased content of (+)-β-pinene in the varieties of Hyssopus officinalis with pink (Rosacea variety) and white (Zaveya variety) aureoles of flowers caused a higher antibacterial activity of their essential oils against Gram-negative and Gram-positive bacteria.

Plants of Helichrysum genus belong to Asteraceae family and abound with species. The’re two species of plants of Helichrysum genus in the Astrakhan region – Helichrysum arenarium Moench and Hеlichrisum nogaicum Zvelev that was discovered later and isn’t studied well enough yet. Helichrysum arenarium is a well-known medical plant widely used in both academic and traditional medicine and included into the State Pharmacopoeia. Inflorescences of Helichrysum arenarium produce cholagogic, hemostatic, detoxicating, laxative, anti-inflammatory and diuretic effects, which is due to content of flavonoids, terpenoids and other components. This works shows results of studies of chemical composition of extracted essential oils of Hеlichrisum nogaicum and Helichrysum arenarium growing in the Astrakhan Region. Samples of essential oils of plants under studies have been obtained by steam distillation. Optimal steam distillation process duration has been determined by experiment taking studies of dynamics of essential oil yield change through time as a ground. Quantitative analysis of main components of Helichrysum arenarium and Hеlichrisum nogaicum essential oils has been carried out by gas-liquid chromatography. It has been identified that Helichrysum arenarium essential oil contains 21 substances. Its main components are camphor (14.59%) and carboxylic acids (37.02%), and 1,8-cineole (5.97%). The main components of the oil Helichrisum nogaicum are camphor (38.33%), borneol (14.21%), cineol-1.8 (11.37%) and terpene-4-ol (5.18%), sesquiterpene compounds (6.28%), and the content of carboxylic acids is insignificant and amounts to 6.58%.

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.
