Abstract

Objective To optimize the extraction process of Xuanfei Zhike Mixture. Methods The preparation process was investigated by L9(34) orthogonal design with content of ephedrine hydrochloride, the extraction rate of n-butanol and total extraction as indexes. The main factors influencing the extraction efficiency such as the amount of added water, the time of extraction and times of boiling were investigated. Results The optimum technical condition was as follows:8 times amount of water, extract 2 times and 60 min for each time. Conclusion The result is reliable. It can be used for mass production.
