Component analysis of the essential oil of the above ground part of Dracocephalum botryoides Steven

The purpose of the study was to study the component composition of the essential oil of the aerial part of Dracocephalum botryoides Steven by chromatography-mass spectrometry to evaluate its use as a promising medicinal raw material. Material and methods. The raw materials for the study were collected in August 2013 during the flowering phase in the Dagestan natural population at an altitude of 2615 m above sea level (Dagestan, Russia). The yellow essential oil (0.31% of the air-dry flow) is obtained by hydrodistillation on a Clevenger apparatus for 4 hours. Results. In the course of the analyzes carried out on the method of chromato-mass spectrometry, 41 components were identified, of which 16 components (α-thuyene, thuya-2,4(10)-diene, sabinene, α-terpinene, p-cymene, γ-terpinene, β -thujone, linalool, α-muurolol, β-elemen, caryophyllene oxide, terpinen-4-ol, γ-elemen, trans-caryophyllene, β-elemenone, γ-muurolen) are the main compounds of D. botryoides essential oil. Three monoterpenes (α-thuyene, sabinene and p-cymene) occur in the maximum amount, which is 48.1% of the total amount of all identified components. Conclusions. For the first time, data are presented on the study of the composition of the essential oil of the aerial part of D. botryoides. Comparison of the results of the component composition of the essential oil of the studied sample with other species of the genus Dracocephalum revealed both similarity and difference in the composition of essential oils. The results obtained make it possible to characterize the essential oil of D. botryoides as a source of valuable components known for their biological activity, which is of great interest for further research
