| Abstract: | The anthocyanin pigment extracted from green-wheat-bran was studied to identify its antioxidant activity.The antioxidant activities of the pigment were evaluated by anti-lipid peroxidation,total antioxidant activity(TAA),superoxide anion radical scavenging activity(SARSA),active oxygen scavenging activity(AOSA),and DPPH(1,1-dipheny1-2 picrylhydrazyl free radical) radical scavenging activity.The results showed that the pigment had higher antioxidant activity and TAA,the capacity increased with the increase of pigment concentration.Its TAA was 51.06 U mL-1,1.73 times of Vc,and SARSA of the pigment,there was a trend that higher concentration performed higher activity significantly improved with the company of Vc.The pigment showed significant antioxidant activities evaluated by different assays.Resuits will provide a better understanding on antioxidant activity of green wheat and allow the screening or breeding of green wheat varieties with higher antioxidant activity for food processing. |
