摘　　要：[目的]为了评价4种香蘑属真菌的抗氧化活性。[方法]对4种香蘑属真菌子实体微波水提物进行抗氧化活性比较分析。[结果]灰褐香蘑(Lepista luscina)、白香蘑(Lepista caespitosa)、紫丁香蘑(Lepista nuda)、花脸香蘑(Lepista sordida)4种香蘑子实体提取物对二苯基苦味酰基苯肼自由基(·DPPH)和羟自由基(·OH)的清除作用较显著,对·DPPH的清除率依次达到73.9%、59.2%、80.7%和82.8%;对·OH的清除率分别达到92.5%、95.7%、83.6%和94.4%。这4种真菌子实体提取物对超氧阴离子亦有一定的清除作用。[结论]4种香蘑真菌子实体中可能存在着活性较强的天然抗氧化活性物质。[Objective]The research aimed to evaluate the antioxidant activity of four kinds of Lepista epiphyte. [Method]The comparative analysis for anti-oxidant activity of fungi microwave water extracts of the four fragrant mushroom fruiting bodies was carried out. [Result]Fungi microwave water extracts of Lepista epiphyte,Lepista luscina,Lepista caespitosa,Lepista nuda and Lepista sordida showed significant clearance,which was 73. 0%,73. 0%,58. 6% and 73. 0% respectively to ·DPPH and 91. 0%,94. 8%,82. 3% and 91. 0% respectively to ·OH in the microwave processed water extract of their fruiting body. Moreover,the fruiting body extracts of the four kinds of fungus showed a clear effect on superoxide anion. [Conclusion] Fruiting body of four kinds of Lepista epiphyte might contain natural antioxidant substances.
