ACCUMULATION OF BIOLOGICALLY ACTIVE SUBSTANCES BY LEAVES OF URTICA DIOICA IN VARIOUS URBAN AND AGRIBIOCENOSES OF VORONEZH REGION

An important and little-studied aspect of the effect of human economic activity on medicinal plants is that in response to increased anthropogenic load, additional synthesis of secondary metabolites, particularly oxycoric acids, is induced, which play an important role in the adaptation of plants to changing conditions. The purpose of the study was to study the accumulation of oxycoric acids in the leaves of nettle collected in different agro- and urbobiogeocenoses of the Voronezh region from the point of view of anthropogenic impact. As part of the study, 51 samples of nettle leaves determined the content of the sum of oxycoric acids in terms of chlorogenic acid. All samples meet the regulatory requirements of this indicator. On average, the content of the sum of oxycoric acids in samples of nettle leaves collected in agrobiogeocenoses does not differ from the content of this group of biologically active substances in samples collected in biocenoses of protected areas. The content of the analysed group of biologically active substances of samples collected in some urbobiogeocenoses of the Voronezh region is on average 1.5–2 times higher than in samples of natural biocenoses of protected areas. This is due to the fact that the enzyme phenylalanine myacliase has a pronounced stress inducibility, which enhances the synthesis of oxycoric acids, which play the role of membrane stabilizers, preventing the penetration of xenobiotics. It was also noted that as a result of the complex toxic effect on the plant organism, which is observed, for example, near large roads, industrial enterprises, it is possible to reduce biosynthesis of oxycoric acids in the leaves of nettle.
