Decoction Process Optimization for Xiaochengqi Decoction by Box-Behnken Response Surface Method / 中国药师

ABSTRACT

Objective:To optimize the decoction process of Xiaochengqi decoction by Box-Behnken response surface method. Methods:Rhein,aloe-emodin and synephrine were chosen as the evaluation indices. After the material-liquid ratio, decocting frequency and decocting time were studied,Box-Behnken response surface method was used to optimize the three factors using the weighted calculation value of the extraction rate of above indicator components. Results:The best conditions were as followsthe material-liquid ratio was 110,the decocting frequency was 3,and the decocting time was 1.0 h. The deviation of measured value and predicted value was 1.15%. Conclusion:The best decocting conditions are promising and reliable.
