| 摘 要： | 以富锌蛹虫草菌丝体水、乙醇、乙酸乙酯提取物为研究材料，对其体外清除O2-自由基、羟自由基和DPPH有机自由基的抗氧化能力进行了测定。结果显示:提取物的浓度越高，对O2-自由基、羟自由基、DPPH的清除率越高。不同溶剂提取物对不同自由基清除率作用不同，当提取物浓度为90 mg/mL时，水提取物对O2-自由基清除率最高可达66.93%，乙醇提取物对羟自由基清除率最高为87.59%，乙酸乙酯提取物对DPPH清除率最高达到100%。

| Abstract: | Superoxide radicals，hydroxyl radicals and organic free radical scavenging capacity were determined by different extracts of zinc-rich mycelial.When concentration of extract became higher，the clearance rate of O2-radicals，hydroxyl radicals，DPPH became higher.When solvents were different，clearance rate of extract on different radicals was different.Clearance rate of 90 mg/mL water extracts on superoxide radicals was up to 66.93%，ethanol extract of hydroxyl radical scavenging rate was up to 87.59%，andethyl acetate extract on DPPH was highest clearance rate，up to 100%. |
