CHEMICAL CONSTITUENTS OF SPHALLEROCARPUS GRACILIS (BESSER EX TREVIR.) ESSENTIAL OILS FROM BURYATIAN FLORA

Abstract

Relevance. Sphallerocarpus gracilis (Besser ex Trevir.) Koso-Pol. (Umbelliferae) is a biennial pubescent plant widely used in the practice of Oriental medicine. Research on S. gracilis is attracting increasing attentiom due to its potential biological zctivities: antioxidant, hepatoprotective effects, anticancer properties, essential oils exhibit significant antimicrobial properties. Material and methods. Essential oils of the aerial part and roots of the Sphallerocarpus gracilis from Mukhorshibirsky district of the Republic of Buryatia, collected during the period of mass flowering (August, 2022), were studied. Essential oils from the herbs and roots were isolated by hydrodistillation method. The content of essential oils was found by 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 the aerial part and roots of Sphallerocarpus gracilis from Buryatian flora studied for the first time. The main components of the essential oils of the aerial part are geranyl tiglate (7.56%) and apiol (71.83%); the roots are γ-terpinene (45.17%), p-cymene (9.38%) and trans-asarone (13.29%). Conclusion. It has been shown that the aerial part of S. gracilis is a rich source of apiol, while the roots – compounds of monoterpene nature.
