The antioxidant activity, total phenolics and total flavonoids content of Bryonia dioica Jacq.

Abstract

Bryonia dioica Jacq. is used as a medicinal plant in traditionalmedicine in the west of Iran. In this study, we investigated anti-oxidant activities, total phenols and flavonoid of several extracts(polar and nonpolar) obtained from B. dioica Jacq. flowers, leavesand stems for two stages of growth (flowering and pre-flower-ing). Several complementary assays, radical scavenging capacity,determination of total flavonoids and reducing power were usedto screen the antioxidant properties of extracts. Large differencesin the composition of phenolic compounds were detected amongflower, leaf, and stem in different stages of growth. In the light ofthe data obtained, B. dioica Jacq. flowers represent an importantsource of phytochemicals with potent antioxidant capacity.
