In this paper, the antioxidant activities of purple cabbage pigment were studied and evaluated by determining the reducing capacity, antioxidant activity on lipid- peroxidation,free radical -scavenging activity on DPPH.At the same time,the anthocyanin contents was mensurated.The results showed that they had stronger reducing capacity,antioxidant activity on lipid-peroxidation,and scavenging effects on DPPH radical. In the range of test concentration, the maximum scavenging or inhibition rate to linoleic acid auto-oxidation,DPPH radical was 54.39 %, 93.2 % respectively.The results suggested that the purple cabbage pigment has antioxidant activities with broad application prospects.
