| 摘 要： | 采用现代分离技术从富硒蛹虫草中提取硒多糖，然后以苯酚-硫酸法、电感耦合等离子体质谱（ICP—MS）法对硒多糖中多糖含量和硒含量进行测定；在Fenton体系的最佳实验条件下，研究了硒多糖对羟自由基的清除作用及硒多糖对支撑磷脂双层膜（Supported Bilayer Lipid Membranes，s—BLM）的保护作用。结果表明：硒多糖清除羟自由基的效果比与之相同浓度的无机硒、多糖都要明显。其中硒多糖对羟自由基的最高清除率可达38．02％，硒多糖具有很强的抗脂质过氧化、保护支撑磷脂双层膜的作用。

| Abstract: | Se-polysaccharide was extracted from chrysalis aweto enriched in Selenium by modern separation technique.The concentration of polysaccharides and selenium in Se-polysaccharide was determined by Phenyl hydrate-sulfuric acid and ICP-MS.The hydroxyl free radical scavenging of Se-polysaccharide and the protective effect of Selenium polysaccharide on s-BLM under optimal conditions of Fenton system were studied.The result indicated that the free radical scavenging of Se-polysaccharide was more obvious than that o... |
