Abstract

Plants of 76 species from 25 families, growing in the forest-steppe zone of Western Siberia, are investigated for the content of low-molecular biologically active substances - flavonoids, tannins, cathechins, coumarins, saponins, аlkaloids. It is established that 33 species are perspective as a source of flavonoids, 29 species - tannins, 21 - coumarins, 13 - saponins, 13 - аlkaloids and 1 - cathechins. Habitats and terms of gathering plants with the high flavonoid content are presented. It is revealed that the largest amount of low-molecular biologically active compounds is present in the representatives of Asteraceae, Lamiaceae, Rosaceae families.
