ANTIRADICAL ACTIVITY OF POLYPHENOLIC COMPOUNDS ISOLATED FROM HELICHRYSUM MARACANDICUM PLANTS
Abstract
Identifying the antioxidant activity of natural substances and assessing their effectiveness is the most important task for the development of new antioxidant systems based on them. The study of the anti-radical possibilities of natural compounds as one of the components of antioxidant activity is one of the methodological approaches used in this work. Identifying the antioxidant activity of natural substances and assessing their effectiveness is the most important task for the development of new antioxidant systems based on them. The study of the anti-radical possibilities of natural compounds as one of the components of antioxidant activity is one of the methodological approaches used in this work. In this work, the antiradical activity (ARA) with respect to the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) of two polyphenolic compounds (summa 1 and summa 2) isolated from plants was studied. The quantitative characteristics of the reduction reaction of DPPH by the studied polyphenols were established.
