The content and composition of the polyphenolics in crystal pomegranate peels from Yunnan province was investigated,and the antioxidant activities were determined.The results showed that the polyphenolic content in crystal pomegranate peels was 99.60 mg/g(DW).P-coumaric acid,(+) catechin and protocatechuic acid were the dominate components,and their contents were 4.80,3.96 and 1.96 mg/g DW,respectively.The polyphenolic extracts showed significant reducing power,DPPH-scavenging activity,lipid peroxidation inhibition ability and nitrite-scavenging capacity.The antioxidant activities of the extracts were significantly positive correlated with polyphenolic content(P<0.01),and the determination coefficient(R2) were in the range of 0.888 1~0.995 8.
