Abstract: ObjectiveTo determine the content of Vitamin E in Vitamin E Cream. Methods RP-HPLC method was used. The chromatographic column was DiamonsilTM C18, the mobile phase was methanol∶chloroform (85∶15), the flow rate was 1.0ml·min-1,the detection wavelength was 284 nm, and the column temperature was 40 ℃. Results The average recoveries for Vitamin E was 99.79%, precision of the method was 0.20%(RSD, n=6). Conclusion The method could be used to determine the content of Vitamin E in Vitamin E Cream.
