摘　　要：利用Fenton反应检测石斛、益母草、沙苑子和白扁豆4种中药中的成分——多糖对羟基自由基和邻苯三酚自氧化体系产生的超氧阴离子自由基的清除作用,并对多糖抗氧化活性进行研究.结果表明,石斛、益母草和白扁豆中的多糖对超氧阴离子自由基和羟基自由基有不同程度的清除作用,而沙苑子中的多糖则具有促氧化活性.To assay scavenging activity of four different Herbal Polysaccharides which included dendrobium polysaccharides,white hyacinth bean polysaccharides,leonurus polysaccharides and astragali semen polysaccharides on hydroxyl radical and superoxide anoin in vitro.It was demonstrated that dendrobium polysaccharides,white hyacinth bean polysaccharides and leonurus polysaccharides had Hydroxyl Radical and superoxide anion free radical Scavenging Activity at different digree.On the contrary,Astragali semen polysaccharides had enzymatic oxidation activity.
