Objective: To optimize ethanol precipitation process of Zhimahuang group in Shufeng Dingchuan granules by analytic hierarchy process (AHP) and information entropy method. Method: With the transfer rates of ephedrine hydrochloride
pseudoephedrine hydrochloride
amygdalin and solid-containing content as comprehensive evaluation index
AHP combined with entropy method was applied to determine the weight of each index
response surface test was used to optimize ethanol precipitation process with the concentration of ethanol after ethanol precipitation process
relative density of concentrated solution and temperature of ethanol precipitation process as factors. Result: Optimum ethanol precipitation process was as follows:the concentration of ethanol after ethanol precipitation process of 75%
relative density of concentrated solution of 1.10 g·mL-1 (25℃)
temperature of ethanol precipitation process at 25℃.Under these conditions
transfer rates of ephedrine hydrochloride
pseudoephedrine hydrochloride
amygdalin and solid-containing content were 95.31%
94.91%
96.02%and 50.29%. Conclusion: Comprehensive evaluation of AHP and entropy method can reflect the importance of different traditional Chinese medicine and the objective test data.It is suitable for optimizing ethanol precipitation process of Zhimahuang group in Shufeng Dingchuan granules.
