OBJECTIVE:To determine the contents of chloromycetin and dexamethasone acetate in Jiefu cream.METHODS:A reversed-phase HPLC was established for the determination with C18 column as stationary phase.The mobile phase consisted of acetonitrile and 0.05%mol/L phosphate buffer solution(40∶60),the detection wavelength was 240nm.RESULTS:Chlorom-ycetin had a good linearity (r=0.9 998) in the range of 0.1~0.3mg/ml,the mean recovery was 100.6% with a RSD of 1.3%.Dexamethasone acetate had a good linearity(r=0.9 998) in the range of 0.02~0.08mg/ml,the mean recovery was 101.1% with a RSD of 1.7%.CONCLUSION:The method is simple,sensitive and accurate.
