【摘要】 研究了升麻多糖的提取及其对羟基自由基的清除作用。采用热水浸提及醇沉法从升麻中提取多糖,通过比色法研究其清除羟基自由基的能力。升麻多糖清除能力与多糖浓度有明显的量效关系,清除50%羟基自由基所需要的多糖浓度为2.4mg/mL,结果表明升麻多糖具有良好的清除羟基自由基的能力。更多还原

【Abstract】 The extraction of polysaccharide fromCimicifuga foetidaand its effect of removal of hydroxyl radicals was studied.The crude Polysaccharide was extracted fromCimicifuga foetidausing hot water-ethanol method. The free radical cleaning effect was studied employing colorimentry method.The results showed that the polysaccharide had the ability to scavenge hydroxyl radicals, which had the dose-effect relationship with the concentration of polysaccharide that was 2.4mg/mL when scavenging 50% hydroxyl radicals.更多还原
