The chromatographic profiles of <em>S. aemiliana</em> and closely related species <em>S. betulifolia</em> Pall and <em>S. beauverdiana</em> Schneid. were compared. Nineteen compounds were detected in 40 % water-ethanol extracts from the leaves of <em>S. aemiliana</em>. Of these, сhlorogenic, p-сoumaric and cinnamic acids, quercetin, kaempferol, hyperoside, isoquercitrin rutin, avicularin, astragalin and dihydroquercetin (taxifolin) were identified. A specific compound in the leaves of <em>S. aemiliana</em> is isoquercitrin, not identified in other closely related species. The chromatographic profiles of <em>S. aemiliana</em> and <em>S. betulifolia</em> are generally very similar. This is additional evidence of the opinion of scientists about the taxonomic rank of <em>S. aemiliana</em> as a subspecies, variation, or form of <em>S. betulifolia</em>. <em>S. aemiliana</em> (the sum of phenolic compounds varies from 16.4 to 23.,88 mg/g) is more similar to <em>S. beauverdiana</em> in the quantitative content of phenolic compounds. Leaves of <em>S. aemiliana</em> contain a lot of hyperoside (up to 9.50 mg/g), which is almost twice as much as that of <em>S. beauverdiana</em> (up to 4.3 mg/g) and 6 times that of <em>S. betulifolia</em> (up to 1.55 mg/g). The revealed difference in the hyperoside content between the three <em>Spiraea</em> taxa is statistically significant.</p> <p>&nbsp;</p&gt;}, number={3}, journal={Acta Biologica Sibirica}, author={Kostikova, V.A. and Kuznetsov, A.A. and Tishchenko, E.D. and Fayzylkhakova, A.N.}, year={2019}, month={Sep.}, pages={15-21} }
