| Abstract: | ：The HPLC method to detect acesulfame potassium, benzoic acid, saccharin sodium, sorbic acid which consisted in tomatoes preserved fruits was optimized. The chromatographic column ODS - Cl8（250mm×4.6mm,5μm） was used, with mobile phase O. 02 mol/L NH4Ac ： Methanol （ volume ratio of 85 ： 15 ） and flow velocity of 1.0mL/min, and UV detector wavelength was 230 nm. The average recovery rate was above 90% , and the RSD was less than 2% （ n = 5 ） , which is suit- able for the need of experiment. |
