Russian. Extracts from the biomass of Chlorella vulgaris C-2019 obtained with extractants of different nature differ in the component composition of BAS and their content, which is confirmed by UV-spectral characteristics. The aqueous extracts of chlorella biomass are characterized by high content of extractives (39.7%), low content of pigments (0.19%) and flavonoids (0.01%). Pigments and flavonoids were found in alcohol extracts. Increasing the concentration of ethyl alcohol from 30 to 95% decreased the amount of extractive substances (from 16.74% to 7.83%), the concentration of pigments (from 0.19% to 1.6%) and flavonoids (from 0.09% to 0.83%) increased. Extracts of nonpolar extractants were distinguished by a high content of flavonoids.
