Abstract:
Objective To optimize the extracting process of the mixture of Feining.Methods Orthogonal design was used to optimize extracting process.The content of glycyrrhizicac,Ephedrine and Pseudoephedrin,and the extractive rate of water and n-butyl alcohol were indexes.Results The optimum water-extracting factors were 8 times of water,refluxing and extracting for 1 h,for 2 times.Conclusion The optimal extraction process is precise and repeatable,which can be used in industrial production.
