Objective: To establish the method of HPLC about the content of vitamin E in dexamethasone acetate cream and to determine the content of vitamin E in dexamethasone acetate cream. Method: The qualitative analysis was performed on Inertsil ODS-SP(4.6 mm×150 mm
5 μm).The mobile phase was methanol-water(98:2) at the flow rate of 1.0 mL·min-1
the detection wavelength was 284 nm and the column temperature was 40℃. Result: The concentration of vitamin E showed a good liner relationship in the range of 0.029 6-0.296 mg·L-1(r=0.999 9)
and the average recovery was 99.70%-101.80%
RSD 0.9%(n=6). Conclusion : After verifying the method
the method is accurate with good reproducibility and can be used for the qualitative analysis of vitamin E in dexamethasone acetate cream.
