Buryatia as a part of Baikalian Siberia is one of the main centers of origin and morphological diversity of wormwood in Eurasia. There are 48 species and subspecies of wormwood within Buryatian flora, one of which is Artemisia gmelinii Web. ex Stechm. For the first time the composition of the essential oils of A. gmelinii growing in the rare community of Siberian apricot ( Armeniaca sibirica (L.) Lam) is presented in this work. Essential oils were obtained from the raw materials collected during the field works on the territory of the Republic of Buryatia (Kyakhtinsky district, surroundings of Tamir village - Southern slopes of the Tamir range) in 2020. The vegetation of the Tamir range’s slope is represented by shrub communities from the relict of Eastern Asia growing since the Miocene-Pliocene time - Armeniaca sibirica . The dominant components of essential oil’s of A. gmelinii from apricot community are 1,8-cineole, germacrene D, camphor, borneol, caryophyllene. Essential oils of A. gmelinii growing within the Siberian flora of one chemotype with a predominance of mono-terpenoids in the group composition form two subtypes, prevailing: 1) in the East Siberian populations of A. gmelinii with a predominance of sesquiterpenoids in the composition of essential oils; 2) in the West Siberian populations of A. gmelinii with a predominance of monoterpenoids in essential oils.
