| Abstract:Objective To optimize the alcohol precipitation process of compound Yinchen mixture by central composite design-response surface method. Methods With the transfer rates of geniposide and solid removal rate as comprehensive evaluation index, the effects of relative density, alcohol concentration, stirring speed and standing time were investigated by the single factor experiment on the alcohol precipitation process. By analysis of variance, the key factors that could influence the alcohol precipitation process were determined. Then the range of parameters of key factors was further studied and explored by central composite design-response surface method. Results The optimum preparation conditions were as follows:the relative density was 1.07, alcohol concentration was 84%,standing time was 8 h,stirring speed was 1762 r/min. Conclusion The alcohol precipitation process of compound Yinchen mixture could be optimized by the response surface method, which could help to enhance the stability of the process. |
