| 摘 要： | 对紫苏粕多糖PWPS的抗氧化活性进行了研究;测定PWPS的还原能力,清除超氧阴离子(O2-.)和羟基自由基(.OH)的能力;结果表明:紫苏粕多糖具有较强的还原能力,对.OH具有一定的清除作用,在低浓度时对O2-.有清除作用,而高浓度时清除作用丧失,表现为促氧化作用。总之,PWPS有一定的抗氧化活性。

| Abstract: | The antioxidant acticities of Perilla meal polysaccharide PWPS were studied in this paper.The power of PWPS for reduction,superoxide anion radical O2- clearance and hydroxy radical -OH clearance was measured respectively.The results indicate that Perilla meal polysaccharide PWPS has strong reducing power,has some effect on scavenging .OH. PWPS has some scavening actibity to O2-.In low concentration but loses the scavenging ability in high concentration and shows prooxidat property in high concentration.In conclusion,PWPS has some antioxidant activitities. |
