Abstract:
OBJECTIVE:To establish a HPLC method for determination of the content of ephedrine hydrochloride in compound Baifu pellicle.METHODS:A XTerra RP 18 column was used.The mobile phase was methanol-1%ammonium acetate solution(40∶60).The detection wavelength was215nm.The column temperature was30℃.The flow rate was0.6ml/min.RESULTS:There was good linearity of ephedrine hydrochloride in the range of0.1034?g～4.136?g(r=0.9994,n=3). The average recovery was101.29%(RSD=2.34%,n=6).CONCLUSION:This method is simple,accurate and repeatable,and can be used for quality control of compound Baifu pellicle.
