摘要：
A quantitative analysis of the total content low-molecular antioxidants in extracts from food and medicinal plants with the help of a method based on the interaction of antioxidants with 2,2-diphenyl-1-picrylhydrazyl (DPPH), a stable radical, and of the amperometric method is performed. The results obtained by these two methods exhibit a high correlation (r = 0.96). A comparative analysis of the total content of anti-oxidants (AOs) in 14 food and medicinal plants and of the activity of these AOs with respect to DPPH was conducted.
