摘　　要：比较平菇(Pleurotus ostreatus)、秀珍菇(Pleurotus geesteranus)、鲍鱼菇(Pleurotus abalones)、杏鲍菇(Pleurotus eryngii)、榆黄菇(Pleurotus citrinopileatus)和红平菇(Pleurotus diamor)6种侧耳属(Pleurotus)食用菌子实体的抗氧化作用,通过FRAP和邻苯三酚自氧化法评价6种食用菌多糖对Fe3+的还原和超氧阴离子的清除能力,检测6种食用菌中超氧化物歧化酶(SOD)的活性。结果表明,鲍鱼菇抗氧化活性最高,总抗氧化能力为327.60μmol/g,超氧化物歧化酶总活力为1 111.85 U/g,对超氧阴离子的清除能力达到66.13%,具有深度研究的价值。The antioxidant activities of fruiting bodies from Pleurotus. sp including Pleurotus ostreatus, Pleurotus geesteranus, Pleurotus abalones, Pleurotus eryngii, Pleurotus citrinopileatus and Pleurotus diamor were determined. The polysaccharide was extracted from mushroom, the reducing capacity toward ferric ion and scavenging capacity of superoxide ion was evaluated by FRAP and pyrogallol oxidation methods. SOD activities from fruiting bodies were also detected to determine antioxidant effect at the same time. It was found that Pleurotus abalones was the advanced strain with antioxidant activity compared with others. The antioxidant effect of Pleurotus abalones has potential for processing applications with total antioxidant capacity of 327.60 μmol/g, SOD activity of 1111.85 U/g and 66.13% scavenging capacity of superoxide ion.
