Abstract
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.
