研究当归多糖（ASP）的提取及其对活性氧自由基的清除作用；ASP提取采用水煮醇沉法粗提，三氯乙酸法去蛋白，Polyerde滤柱膜吸附洗脱精制；采用分光光度法测定当归多糖对O-·2和OH·的抑制作用；粗品ASP对O-·2和OH·清除率分别可达42.6%和38.7%，精品ASP对二者的清除率分别可达35.7%和29.4%；ASP对O-·2和OH·均有良好的清除能力.

Study on isolation of the Angelica Sinensis polysaccharide (ASP) and its effects on anti-active oxygen free radical is presented in this paper. Isolation of ASP was extracted by hot water and alcohol precipitation,and purified by absorbent with Polyerde column membrane and eluted with hot water. Scavenge rate to O -· 2 and OH · with the crude ASP were 42.6% and 38.7% respectively;and with pure ASP were 35.7% and 29.4% respectively. The ASP was ...
