摘　　要：　通过对魔芋葡甘露聚糖提纯方法的比较,提出一种魔芋葡甘露聚糖提纯的改进方法.研究了提纯的魔芋葡甘露聚糖用氯乙酸改性,其改性的合理条件为:1g经纯化的魔芋葡甘露聚糖,加入85%的乙醇10mL,40%的氢氧化钠25mL,加热1 5h后,再加入83%的氯乙酸5mL,反应2 5h.A optimum method for purifying Konjac glucomannan is found through comparative study of various methods.The purtified Konjac glucomannan is denatured with chloroethanoic acid.Studies on reaction condition of chloroethanoic acid denaturation of konjac glucomannan. The results indicate:1g purtified konjac glucomannan, 10mL 85% ethanol,25mL 40% NaOH,1.5h,5mL 83% ClCH_3COOH,2.5h.30-40℃ is the optimum reaction condition.
