Abstract
The content of biologically active substances (flavonols, catechins, tannins, carotenoids) was studied for 45 samples of amaranth (Amaranthus L.) of different geographical origin, grown at the experimental plot of the Institute of Cytology and Genetics of the SB RAS (Novosibirsk). Amaranth leaves contain up to 3.2 % of flavonols, 0.33 % of catechins, 10.7 % of tannins, 101.4 mg% of carotenoids, whereas the flowers contain up to 3.1, 0.19, 11.3 %, and 32.3 mg %, respectively. A significant variation in the characteristics under testing has been revealed, which allows one to carry out the selection for increasing the content of either substance, and to use available species as feedstock sources.
