RESEARCH ON THE COMPOSITION AND CONTENT OF BIOLOGICALLY ACTIVE SUBSTANCES OF FAR EAST REPRESENTATIVES OF GENUS <i>SPIRAEA </i>(<i>ROSACEAE</i>)
A comparative analysis of the main groups of biologically active compounds in the leaves and infl orescences of plants of nine species of the <i>Spiraea </i>L. genus from Russian Far East natural and introduction populations is carried out. Widespread species of the genus <i>Spiraea </i>characterized by the high content of active substances. Th e content of catechins, anthocyanins, saponins and sugars in infl orescences more than the leaves, tannins accumulated more in leaves. Diff erences of species of the correlation glycosides of quercetin and kaempferol are revealed. Plants <i>S. pubescens </i>diff erent by the high content of quercetin glycosides (1.61 %) and <i>S. ussuriensis </i>- kaempferol glycosides (1.77 %).
