Abstract: Objective To establish the optimal ethanol extraction technology of Qingshen Granule. Methods The total content of emodin, chrysophanol and physcion, the content of tanshinoneⅡA and dry extact rate was set as indexes, orthogonal test was adopted to optimize the technology. Results The optimum extraction conditions were as follows:8 times of 80%alcohol, refluxing 3 times and 2 hours for each time. Conclusion The optimum technology of Qingshen Granule is simple, stable and effective.
