Objective: To establish a dual wavelength UV-spectrophotometric method for the determination of vitamin E in allantion vitamin E cream. Methods: The UV-visible spectrophotometer was used for content determination of vitamin E.The detection wavelength and reference wavelength were 285 nm and 293.2 nm，respectively.Results：The linear range of vitamin E was 31.96-95.88 μg/ml（r=0.999 9. The average recovery was 100.80%，RSD was 1.21%（n=9）.Conclusion：The method was more accurate，sensitive，specific and reproducible.It could provide the reference for the improvement of the quality standards of allantion vitamin E cream.
