Study on Antioxidant Activity of Anthocyanin Pigment from Black Corn

Xianjun Meng

Abstract

In this paper, the antioxidant activities of black corn pigment were studied and evaluated by determining the reducing capacity, antioxidant activity on lipid-peroxidation, free radical-scavenging activity on DPPH and superoxide anion. The results showed that they had stronger reducing capacity, antioxidant activity on lipid-peroxidation, and scavenging effects on DPPH radical and superoxide anion. In the range of test concentration, the maximum scavenging or inhibition rate to linoleic acid auto-oxidation, DPPH radical and super oxide anion was 52.05%, 95.61% and 77.45% respectively, the results suggested that black corn pigment has antioxidant activities and broad application prospects.
