Abstract:
Objective To evaluate the antioxidant activity of different concentrations of alcohol extracts from Paeonia Rockii pollen.Methods The antioxidant activity of different concentrations of alcohol extracts from Paeonia Rockii pollen was evaluated by cupric reducing power method, DPPH radical scavenging activity method and ABTS radical scavenging activity method.Results The amounts of antioxidant activity of gallic acid of anhydrous ethanol extract, 75％ alcohol extract, 50％ alcohol extract, 25％ alcohol extract, and water extract from Paeonia Rockii pollen were 26.00, 28.33, 28.90, 14.98, and 9.24 mg/g, respectively. The sequence of the ability of scavenging DPPH free radical and ABTS radical was Vc > 50％ alcohol extract > 75％ alcohol extract > anhydrous ethanol extract > 25％ alcohol extract > water extract.Conclusion The different concentrations of alcohol extracts from Paeonia Rockii pollen has relatively strong antioxidant activity, especially for 50％ alcohol extract and 75％ alcohol extract.
