| Abstract: | Objective] To determine the antioxidant activity of anthocyanin from blueberry.Method] The anthocyanin were extracted with acidified ethanol from the fresh blueberry and the antioxidant activities of blueberry anthocyanin were determined by.OH,DPPH.,H2O2,superoxide anion and Fe3 ＋ removal experiments.Result]The.OH,DPPH.,H2O2,superoxide anion and Fe3 ＋ removal rates of blueberry anthocyanin increased with its concentrations and were superior to that of Vc at the same concentration.Conclusion] Blueberry anthocyanin possessed high antioxidant activity,which can be developed as natural antioxidants. |
