Study on Antioxidant Activity of Flavonoids Peony
DOU Yong-bo
Abstract：The peony is China's characteristic of woody rare flowers. Flavonoids widely exist in many kinds of plants, and in the form of glycosides. The antioxidant activity of flavonoids of peony were studied from 3 aspects of DPPH· scavenging activity, ·OH scavenging activity and reducing power in this experiment. The results showed that flavonoids of peony have reducing power and scavenging activity of ·OH and DPPH·. The IC50 of scavenging activity of DPPH·and ·OH were 259.29μg/mL and 1573.53μg/mL, the reducing power of per gram flavonoids of peony flower was equivalent to 213.07mg of ascorbic acid and 993.67mg of rutin.
