Abstract

OBJECTIVE:To optimize the extraction technology of Fengshi Ⅱ mixture.METHODS:Decoction,microwave extraction and ultrasonic extraction were applied.The extraction method was optimized with content of chlorogenic acid and harpagoside,the yield of extraction as index.The extraction technology was optimized by orthogonal experiment.RESULTS:Decoction is the optimal extraction method,and the optimal extraction technology was as follows:10-fold water,no marinating,extracting for 3 times and for 1 hour.CONCLUSION:The extraction technology is reasonable and reliable,which provide theory basis for the preparation of Fengshi Ⅱ mixture.
