Antioxidant properties of Bergenia crassifolia extract

Ethanol extracts from Bergenia crassifolia (L.) Fritsch. green leaves exhibit antioxidant properties. The most significant activity has been observed for 70% ethanol extract, which is a typical acceptor of peroxy radicals. Fractionation of the active extract yielded chloroform and ethyl acetate fractions, which also showed a pronounced antioxidant action. Phenolic compounds (hydroquinone, quercetin, dihydroquercetin, rutin, gallic acid, esculetin) also exhibited significant antioxidant activity comparable with that of ionol.
