| Abstract: | In order to optimize the extraction conditions of Glycyrrhiza polysaccharides（ GPS）, test factors and levels were firstly select- ed by one-factor tests. On the basis of previous results, the method of response surface methodology （RSM） with 3 factors and 3 levels was adopted. Response surface and contour are finally graphed with the extraction rate of GPS as the response value. The results showed that the optimum conditions of GPS extraction are ： ratio of water to material of 31 ： 1, extraction time of 2.1 h, extraction tem- perature of 63℃ , the extraction rate of GPS is up to 10.23%. |
