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