Study on Extraction Technique of Patch of Kechuan Plaster
Objective:To investigate the optimal extraction technique patch of Kechuan Plaster.Method:The extraction technique was optimized by orthogonal experimental design and the content of ephedrine chloride was used as the inspecting mark.Results:The optimal extraction technique was that the raw material was refluxed with 65% ethanol whose volume was 6 times than that of the raw material for 3 times lasting 1.5h for each time.Conclusion:The extraction technique is stable and feasible.
