Phytochemical study and evaluation of the antioxidant activity of the fruits of Sorbus aucuparia L. and Sorbus intermedia (Ehrh.) Pers. growing on the territory of the Donetsk region

It was found that the fruits of Sorbus aucuparia and Sorbus intermedia , growing in Donbas, contain significant amounts of flavonoids, ascorbic, free organic and oxycinnamic acids and exhibit high antioxidant activity, which proves their value in medical practice. It has been established that increasing the degree of technogenic pollution causes a decrease in the amount of flavonoids, tannins, carotenoids, ascorbic, free organic and oxycinnamic acids and an increase in the content of anthocyanins in the studied raw material. Ecological safety of raw materials was estimated.
