Abstract
The article presents an analysis of the influence of technogenic pollution on the content of the main groups of biologically active substances (flavonoids, anthocyanins, oxycinnamic acids, procyanidins, tannins, carotenoids, ascorbic and free organic acids) in the fruits and leaves of the representative of the natural flora of Donetsk region Crataegus fallacina Klokov. The content of heavy metals such as cadmium, lead, mercury in the soil (mobile forms) and plant materials was determined, and the environmental safety of the raw materials was evaluated. It was revealed that a significant increase in the content of tannins in the leaves of C. fallacina , as well as a decrease in the content of procynidins in the fruits in anthropogenic conditions, can be recommended for screening the degree of impact of an urbanized environment on plants. The conformity of the raw materials of C. fallacina to the requirements of the regulatory documents for the content of active substances was evaluated. It was shown that this raw material has a high antioxidant activity, which increases in conditions of pollution.
