Objective To establish a method for determining the content of Weigan creams and to predict the expiration date of the creams stored at room temperature. Methods K ratio spectrophotometry was used to measure the content of vitamin E, so was Q10 method to predict the expiration date of Weigan creams Results Vitamin E at concentrations of 71.5 to 135.8 μg/ml has a better linear relationship with the standard curve. The average rate of reclaimable vitamin E was 96.9%, with RSD of 0.56%. The expiration date (t0.9) of the Weigan creams stored at 25℃ was 16.8 months. Conclusions The method is simple and rapid, with accurate and reliable results. It can be used in the quality control of Weigan creams.
