| 摘 要： | 分别采用高效凝胶渗透色谱法(HPGPC)和气相色谱法(GC)分析黑灵芝菌盖、菌柄和孢子粉多糖的分子质量分布和单糖组成，结果表明三者存在显著性差异。对三者的抗氧化活性进行考察，结果表明：菌盖多糖在清除羟自由基和总还原能力(FRAP)方面效果最佳；菌柄多糖在清除DPPH 自由基、羟自由基和抑制β- 胡萝卜素与亚油酸体系氧化方面效果显著；孢子粉多糖的体外抗氧化效果较差，但在金属离子螯合能力方面明显优于菌盖和菌柄多糖。

| Abstract: | In this study,the molecular weight distribution and monosaccharide composition of polysaccharides from the pileus,stipe and spore of Ganoderma atrum were analyzed by using high performance gel permeation chromatography(HPGPC) and gas chromatography(GC),respectively.Significant differences were found among the polysaccharides from the three different parts of Ganoderma atrum,which were also tested for their antioxidant activity.The polysaccharide from Ganoderma atrum pileus possessed the best hydroxyl free r... |
