Abstract

Aim. The aim of the work was to evaluate the anti-radical activity of extracts of ginseng's underground and overground organs Panax ginseng C.A. Mey, depending on various factors – age of plants, collection time and cultivation conditions. Methods. Extracts obtained from various plant organs were evaluated in the model system with cation-radicals ABTS. At the same time, the amount of extractive substances and phenolic compounds was determined. Results. Samples of leaves and roots of ginseng of 1, 2, 3, 5, 9 years of vegetation from the collection of the Central Botanical Garden of the National Academy of Sciences of Belarus were analyzed. It is established that extracts of ginseng leaves of P. ginseng can be considered as sufficiently effective anti-radical agents. Anti-radical activity of extracts of roots and leaves of ginseng differed significantly depending on the weather conditions of the growing season. Conclusions. It is shown that extracts of ginseng leaves differ by the maximum antiradical activity. Extracts of ginseng roots showed a much lower anti-radical activity in comparison with leaf extracts, which may be due to both a smaller amount of extractives extracted from water-ethanol extraction and their composition.

Keywords: ginseng, antiradical activity, phenolic compounds, extractives.
