| Abstract: | OBJECTIVE To study a simple and rapid method to determine vitamin A in the ChengzhiYuyou(made from orange juice and fish liver oil). METHODS Vitamin A extracted from ChengzhiYuyou by using cyclohexane was determined by using the first derivative spectrophotometry. RESULTS The average recovery was 99.25% and the coefficient of variation was 2.66%(n=6). CONCLUSION The method is simple, rapid and needs less amount of reagent. |
