  • Objective: To establish a method for simultaneous determination of ketoconazole and clobetasol propionate in compound ketoconazole gel. Methods: HPLC method was developed.Chromatographic conditions included Hypersil ODS2 C18 column and the mo- bile phase was methanol-0.2% triethylamine（adjust with acetic acid to a pH of 6.9,V:V=75:25）.The flow rate was 1.0 mL/ min and the UV detection wavelength was at 239 nm. Results: Ketoconazole had a good linearity（r=0.9999） in the range of 10.08～201.16μg/mL,its average recovery was 99.59%（RSD=0.77%）.Clobetasol propionate had a good linearity（r=0.9998） in the range of 0.251～5.02μg/mL,its average recovery was 100.76%（RSD=1.18%）. Conclusion: The method was simple, sensitive and accurate for simultaneous determination of the two constituents in compound ketoconazole gel.
