Comparison of the Antioxidant Activity of the Bark Extracts of Myrica esculenta, Phyllanthus emblica and Larix gmelinii
摘要
Abstract
Proanthocyanidins, which are the predominant compounds of the bark extracts of Myrica esculenta, Phyllanlus embtica and Larix gmelini, were separated and purified in the present study. Three different systems, I. E. , the DPPH radical scavenging assay,FRAP and lipid peroxidation inhibitory activity were used to investigate the antioxidant activity of the extracts. The results showed that all three extracts had high antioxidant activity. The bark extracts of M. Esculenta had a stronger antioxidant ability than those of P. Emblica and L. Gmelini. The structure-activity relationship of proanthocyanidins was confirmed on the basis of the results obtained. The more hydroxyl groups (-OH) of these compounds might contribute to the higher antioxidant activity.关键词
