Abstract：Objective To optimize the extraction process of the combination of Angelica dahurica and Ligusticum sinense Oliv.Methods The preparation process was investigated by L9(34 )orthogonal design with content of imperatorin and the rate of extractum as indexes,using the determination of the content of imperatorin by HPLC.The main factors influ-encing the extraction efficiency such as the amount of added ethanol,ethanol concentration,the time of extraction and times of extraction were investigated.Results The optimum technical condition was as follows:8 times amount of 80% ethanol of soaking 1 hours,extract 3 times and 90 minutes for each time.Conclusion The optimized extraction process was simple, stable and feasible,it can be used in the preparation.
