Ecological Valence of Rosa corymbifera Borkh. to Conditions of the Technogenic Environment

This 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 a technogenic environment (using the region of Donetsk as an example), an increase in the concentration of anthocyanins, tannins, and oxycinnamic acids and a decrease in the level of flavonoids, ascorbic acid, and polysaccharides have been revealed. Under the conditions of anthropogenic pressure, the content of flavonoids changes most significantly. A significant increase (2 times) in antioxidant activity under conditions of technogenic load is revealed. The interrelation of the content of heavy metals (lead, cadmium, and mercury) in the soil (mobile forms) and fruits is evaluated. The conformity of fruits of R. corymbifera plants growing in the Donetsk region to the requirements of the regulatory documents is evaluated.
