Abstract:
OBJECTIVE:To find out the optimal extraction technique for Biyanning granulesMETHODS:According to the orthogonal design L9(34),the optimal extraction technique was sought through experimental investigation,and the content of the imperatorin in Radix Angelicae Dahuricae,a main herb in Biyanning granules,was determined by HPLCRESULTS:With the optimal extraction method,the extraction rate of the imperatorin in Biyanning granules was 5766%CONCLUSION:The results indicates that the extraction technique which we found out is optimal and feasible in extraction of Biyanning granules
