Title: Antioxidant Activity of Aqueous and Ethanolic Extracts from Blueberry Leaves
Abstract: Aqueous and ethanolic extracts were extracted from blueberry leaves. Anti-lipid peroxidation, reducing power, scavenging hydroxyl radicals, superoxide anion radical and DPPH radical of aqueous and ethanolic extracts from blueberry leaves were determinated by in vitro chemical system. The results showed that aqueous and ethanolic extracts from blueberry leaves strongly inhibited lipid peroxidation, enhanced reduction power, scavenged hydroxyl radical, superoxide anion radical and DPPH· radical. Aqueous and ethanolic extracts from blueberry leaves were enhanced on anti-lipid peroxidation, reducing power, scavenging free radical activity with increasing their concentration. Ethanolic extracts were stronger than aqueous extracts on anti-lipid peroxidation ability, whereas they were weaker than aqueous extracts on scavenging hydroxyl radical, superoxide anion radical and DPPH radical. There was not any significant difference between them on reduction power. Blueberry leaves extracts have characteristics of antioxidant effect on lipid peroxidation and free radical and it can be applied as an effective natural antioxidant.
