Objective:To optimize the extraction technique of Qinggongxiaoyan Suppository.Methods:The extraction technique was optimized by orthogonal experimental design and the contents of matrine and oxymatrine were used as the inspecting marks.Results:The optimal extraction technique was that the material was extracted with water whose volume was 8 times than that of the material for 3 times and lasting 1.5 h for each time.Conclusion:The times for extraction is the main parameter affecting the contents of matrine and oxymatrine.
