Abstract
The article presents an analysis of the influence of technogenic pollution on the content of biologically active substances and the antioxidant activity of the fruits of Rosa corymbifera Borkh. In the technogenic environment (on the example of the Donetsk region) were revealed an increase in the concentration of anthocyanins, tannins and oxycinnamic acids and a decrease in the level of flavonoids, ascorbic acid and polysaccharides. In the conditions of anthropogenic pressure, the content of flavonoids changes most significantly. A significant (2 times) increase in antioxidant activity under conditions of technogenic load was revealed. The interrelation of the content of heavy metals (lead, cadmium, mercury) in the soil (mobile forms) and fruits was evaluated. The conformity of the fruits of plants R. corymbifera, growing in the Donetsk region, to the requirements of the regulatory documents was evaluated.
