Objective: To optimize the extraction technology of Yizheng Huomai pill. Method: The content of the total amount of ursolic acid and oleanolic acid was detected by HPLC and orthogonal experiment was used to research the best procedure with the rate of extractum as index. Result: The optimum process was A1B2C3D2
10 fold of 90% ethanol
decocting 2times and 1.5 h each time. Conclusion: The optimum technology of Yizheng Huomai pill is simple
