棕色双孢蘑菇子实体不同生长阶段抗氧化活性比较

Comparison of antioxidant activity of the extracts from the fruiting body of brown Agaricus bisporus at different growth stages

为了探明棕色双孢蘑菇子实体不同生长阶段抗氧化活性的差异,系统地比较了4个不同成熟度:A—幼菇期、B—正常采收期、C—刚开伞期和D—孢子成熟期的棕色双孢蘑菇子实体的甲醇提取液总酚含量和抗氧化能力。结果表明:不同生长期的棕色双孢蘑菇子实体总酚含量及抗氧化活性差异显著,B时期提取液具有最高的总酚含量和较强的抗氧化活性。

In order to ascertain difference in antioxidant activity of the extracts from the fruiting body of brown Agaricus bisporus at different growth stages,the total polyphenol contents and antioxidant activities of methanolic extracts of the fruiting body at four growth stages including A-young mushroom period,B-normal harvest period,C-open veil period and D-spore matured period were comprehensively compared. The results indicated that there were significant differences in total polyphenol contents and antioxidant activities among the four growth stages. Extracts from growth stage B demonstrated the highest total polyphenol contents and the best antioxidant activities.
