摘　　要：采用热水浸提法,提取茶树菇多糖并进行初步纯化,采用水杨酸法、邻苯三酚自氧化法,研究茶树菇多糖清除·OH和O2-·的效果;用硫代巴比妥酸(TBA)法测定对蚕蛹油的抗脂质过氧化作用,结果表明:茶树菇多糖具有较强的清除·OH和O2-·的作用,对蚕蛹油的抗氧化作用效果较弱。The extraction methods of Agrocyb Aegerita Polysaccharid including hot water extraction,the scavenging effect of Agrocyb Aegerita polysaccharide on hydroxyl radicals （·OH）and oxygen radicals （O2-·） were tested by salicylic acid method.Studying inhibition effect on Silkworm oils oxidation system by hiobaribituric acid （TBA）,The result showed that Agrocyb Aegerita Polysaccharid can detcting hydroxyl radicals（·OH）and oxygen radicals（O2-·）deeply but poorly to 1ipid peroxide.
