Abstract
The data on the concentrations of phenolic compounds, photosynthetic pigments, pectin substances and triterpenoid saponins in the leaves of Chlorophytum сomosum Thunb. Jacques are presented, the antioxidant and antiviral activity of the extracts of this plant species is assessed. High concentrations of chlorophyll a and b (434.67 and 245.11 mg/100 g, respectively), tannins (82.34 mg/g), catechins (0.73 mg/g), hydroxycinnamic acids (36.67 mg/g), saponins (64.53 mg/g), carotenoids (75.70 mg/100 g) and pectin substances are detected in the leaves of this plant species. The total content of phenolic compounds and flavonols was termed as insignificant. The water-ethanol extracts of the leaves exhibited antiradical activity in the reaction with the stable free radical 2,2-diphenyl-1-picrylhydrazyl. The antiviral activity of the aqueous extract was detected with respect to the avian virus A/chicken/ Kurgan/05/2005 (H5N1).
