Most of the wormwoods of the region are xerophytes and mesoxerophytes, belonging to the steppe and forest-steppe ecological-coenotic groups (34 species, 70.8%), mainly from the sections of <em>Artemisia</em>, <em>Abrotanum</em>, and <em>Campestris</em>. Ecological-geographically, Central Asian, South Siberian, and North Asian species dominate, accounting for 45.8% of the total species composition with significant share of species with wide Eurasian distribution area (8 species, 16.6%). Endemism is peculiar to the species of psammophyte-steppe (<em>Artemisia ledebouriana</em>, <em>A. xylorhiza</em>) and mountain-steppe (<em>Artemisia subviscosa</em>) genesis (3 species, 6.25%). In the systematic relation, interpretations of a taxonomical variety on separate sections are ambiguous, among them there is <em>Campestris</em>, <em>Absinthium</em>, <em>Abrotanum</em>. In the section <em>Abrotanum</em> the identification of species close to <em>Artemisia gmelinii</em> is problematic. As a result of a detailed study of the composition of the essential oil, the additional chemotaxonomic criteria for the taxonomic status of <em>Artemisia messerschmidtiana </em>and<em> A. santolinifolia</em> were suggested. So, the presence of davanone components in the oil of <em>Artemisia santolinifolia</em> can be the taxonomic sign of this species. Specific components in high concentrations were also found in the composition of <em>Artemisia messerschmidtiana</em>, namely trans-Sabinene hydrate (2.4%), gamma-Terpinene (2.0%), and Germacrene D (1.6%).</p&gt;}, number={3}, journal={Acta Biologica Sibirica}, author={Namzalov, B.B. and Zhigzhitzhapova, S.V. and Dubrovsky, N.G. and Sakhyaeva, A.B. and Radnaeva, L.D.}, year={2019}, month={Oct.}, pages={178-187} }
