摘要

目的:筛选薯蓣多糖的最佳脱蛋白方法。方法:以脱蛋白率和多糖残留量为指标，对4种脱蛋白方法进行评价。结果:PapainSevage法脱蛋白率为91，效果最好。24%, 80。剩余12%的多糖。脱蛋白的最佳条件为:用2。0%木瓜蛋白酶(h7)0)在55℃下放置122 min，用Sevage法放置1次。结论:木瓜蛋白酶法是纯化薯蓣多糖的最佳脱蛋白方法。

[Study on Deproteinization of Polysaccharides from Dioscorea nipponica].

Objective: To screen the optimum method for deproteination of Dioscorea nipponica polysaccharides.

Methods: The ratio of protein removing and polysaccharides remaining were used as indicator,four deproteination methods were evaluated.

Results: PapainSevage method was the best one, in which the deproteination rate was 91. 24%,and 80. 12% of polysaccharide was remained. The optimum conditions for deproteinization were as follows, hydrolysing the substrates with 2. 0% papain( p H 7. 0) at 55 ℃ for 122 min, and one times with Sevage method.

Conclusion: The papain-Sevage is the best deproteination method for purifying Dioscorea nipponica polysaccharides.
