中文摘要：

目的：探讨绵地花菌黄酮类化合物的抗氧化活性。方法：采用有机溶剂萃取的方法,获取绵地花菌子实体黄酮类化合物,以VC作为对照,测定清除DPPH·、羟基自由基、亚硝酸盐、超氧阴离子的能力等指标。结果：绵地花菌黄酮类化合物能有效的清除DPPH·、羟自由基、亚硝酸盐和超氧阴离子,其清除能力的大小与浓度呈正相关。结论：绵地花菌黄酮类化合物具有较强的体外抗氧化活性。

英文摘要：

Objective：To discuss antioxidant activity in vitro of flavonoids from AlbatreUus ovinus （FAO）. Meth-od： The flavonoids were derived from fruiting body of A. ovinus using solvent extraction method. The antioxidantactivity of FAO was evaluated by determining its capability in eliminating DPPH , hydroxyl radical, sodium ni-trite and superoxide anion free radical, in comparison with Vc. Results： The FAO are greatly effective in sea -venging DPPH , hydroxyl radical, sodium nitrite and superoxide anion free radical, whose activities were posi-tively correlated with its concentration. Conclusion： The FAO have good antioxidant activity in vitro.
