Relevance. The genus Bupleurum L. plants are one of the sources of biologically active substances. Determination of the qualitative composition and quantitative content of the essential oils components is necessary for the standardization of a new type of medicinal plant material. Purpose of research. Investigation of essential oils composition of Bupleurum bicaule from Buryatia flora. Material and methods. Plant materials were collected in the Khorinsk district of the Republic of Buryatia during the flowering period (July 2019). Es-sential oils from the herbs and roots were isolated by hydrodistillation method. The content of essential oils was found by the volumetric method. The qualitative composition and quantitative content of essential oils components were determined by gas chromatography-mass spectrometry method. Results. The qualitative composition and quantitative content of essential oils components of herbs and roots of the B. bicaule from Buryatia flora have been studied for the first time. The main components of essential oils from aerial part are β-myrcene (6.74%), trans-β-ocymene (18.75%), limo-nene (6.67%), β-pinene (5.28%), germacrene D (18.34%), caryophyllene (9.05%), bicyclogermacrene (7.61%) and undecane (5.35%). For essential oils of the roots, the main components are bicyclogermacrene (7.95%) and 6-tridecene-4-yne (71.64%). Conclusions. It has been shown that the aerial part of the B. bicaule is a rich source of terpene compounds, while the roots are source of polyyne compounds.
