Study of the variability of the component composition of the essential oil of Artemisia vulgaris L. from the place of collection of raw materials in the territory of Dagestan

Abstract

The genus Artemisia L. is represented in the natural flora of Dagestan (Russia) by 21 species. For the first time, data are presented on the release of essential oil and its component composition in the aerial part of Artemisia vulgaris L., collected in different geographical points during the flowering period in 2014. The aim of the work was to assess the dependence of the accumulation and variability of the component composition of the essential oil of the aerial part of A. vulgaris on the place of collection of raw materials. The collected raw materials were dried to an air-dry state, ground in a laboratory mill and subjected to extraction by the Clevenger method (hydrodistillation method). The studied samples of wormwood showed a low content of essential oil, and one sample was colored dark blue, which differs from the literature data. The resulting essential oils were further analyzed on a gas chromatography-mass spectrometer (Shimadzu). As a result, 51 compounds were found in the essential oil of the aerial part of A. vulgaris (a sample collected in the vicinity of the village of Charoda, 1490 m above sea level, Dagestan, Russia), 56 compounds in a sample collected in the vicinity of the village of Kurush, 2460 m above sea level, Dagestan, Russia. Pinene beta, sabinene, myrcene, eucalyptol, terpinene gamma, thujone –beta, Verbenol trans, terpinen –4 –ol, chrysanthenyl acetate – trans, Isogermacrene D, muurolene epsylon, Humulene alpha, Cadinene gamma, Selyptol –Beta, Bulnesene alpha, Caryophyllene oxide, Humulene epoxide II, Chamazulene. Bulnesene alpha, Caryophyllene oxide, Humulene epoxide II, Chamazulene. Two samples of A. vulgaris essential oil differ in general both in qualitative and quantitative composition of components, both major and minor. The results obtained give us grounds to recommend these samples as sources of valuable components, chamazulene, Chrysanthenyl acetate, cubebene beta and others.
