| Abstract: | The method of determination of Benzoic Acid（sodium）,Sorbic Acid（potassium）,Saccharin Sodium in Haw Products by high performance liquid chromatography was optimized.the method of sample preparation was adjusted accordingly.The separation was achieved by using a C18 column（150mm×4.6mm）with mobile phase 0.02mol/L NH4Ac/methanol（95/5）,lastly the determination was conducted at 230 nm through a UV detector.The average recovery of the method in real samples was more than 95.25%,and the RSD was less than 2%,the method is suitable for the need of experiment. |
