中文摘要：

为了促进蛇莓的综合利用,采用总抗氧化能力、·OH清除率和DPPH·清除率来考察蛇莓总多酚的体外抗氧化活性。结果表明：蛇莓总多酚总抗氧化能力高于VC,且蛇莓总多酚的·OH清除率远高于VC。此外,蛇莓总多酚对DPPH·的IC50（18.2μg·mL-1）与VC（IC50=17.6μg·mL-1）相近。蛇莓总多酚是天然的抗氧化活性剂和自由基清除剂。

英文摘要：

In order to promote the comprehensive utilization of Duchesnea indica Focke ,the antioxidant activity in vitro of total polyphenol from Duchesnea indica Focke was evaluated by total antioxidant activity ,hydroxyl and DPPH free radical scavenging activity .The results showed that the total antioxidant activity of total poly-phenol from Duchesnea indica Focke was slightly higher than VC ,and the hydroxyl free radical scavenging ac-tivity of total polyphenol from Duchesnea indica Focke was much higher than VC .In addition ,the half-maximal inhibitory concentration（IC50 ）for DPPH free radicals of total polyphenol from Duchesnea indica Focke and VC was similar ,which was 18 .2 and 17 .6μg·mL-1 ,respectively .Total polyphenol from Duchesnea indica Focke is natural antioxidant and free radical scavenger .
