To evaluate the antioxidant activity of jujube,the total phenolic and flavanoid contents of extracts obtained by 80 % methanol(v/v) from different parts of jujube(pulp,seed and peel) are determined.the total antioxidant activity,1,1-diphenyl-2-picrylhydrazyl radical(DPPH·) scavenging activity and hydroxyl(·OH) radical scavenging activity are evaluated in vitro.The results indicate that the extracts of jujube peel showed higher total phenolic and flavanoid contents and the stronger total antioxidant power and DPPH· and ·OH scavenging activity than those from pulp and seed.Furthermore,the antioxidant activity are significantly correlated with total phenolic and flavanoid contents.
