【Abstract】 The influence of extraction temperature,time,pH on the extraction rate of polysaccharides from Coix lachryma-jobi kernel was studied.A well fitted quadric regression model was developed and the optimum exaction conditions were obtained.The response of the polysaccharides yield to all three single factors and their interactions were discussed.With the extraction process composed of temperature of 105℃,time of 3.3 hours and pH of 5.2,the polysaccharides yield was pretty high.更多还原
