| 摘 要： | 目的]探讨海蒿子多糖（SPPS）体外抗氧化作用。方法]利用H2O2/Fe2＋体系、邻苯三酚自氧化体系及卵黄脂蛋白LPO体系,研究SPPS对羟基自由基（.OH）、超氧阴离子自由基（O2-·）的清除作用及对卵黄蛋白（LPO）的抑制作用。结果]SPPS具有明显的抗氧化作用,其浓度为200μg/m l时,对·OH清除率为26%,对O2-·的清除率为80%,对LPO的抑制率为40%。结论]SPPS具有抗氧化方面的应用开发前景。

| Abstract: | Objective] To investigate antioxidant activities of S.pallidfum polysaccharides(SPPS)in vitro.Method] H2O2/Fe2+ system,pyrogallol system,LPO system were employed to evaluate SPPS ability to scavenge hydroxyl,LPO and superoxide radical.Result] 26% hydroxyl radical,80% superoxide radical and 40% LPO could be eliminated by 200 μg/ml SPPS.Conclusion] SPPS were potential anti-oxidant sources. |
