High performance liquid chromatography (HPLC) with fluorescence detector was used to determine salicylic acid (SA) and its main hydroxylated products, 2,3-dihydroxybenzoic acid (2,3-DHBA) and 2,5-dihydroxybenzoic acid (2,5-DHBA)． Mobile phase was 30 mmol/L acetate(pH 4．9) and the flow rate was 1．0 mL/min． Low detection limits, 10 nmol/L for 2,3-DHBA, 0．6 nmol/L for 2,5-DHBA and 1．0 nmol/L for SA were obtained． The photolysis system of salicylic acid and H\-2O\-2 was investigated． The products in the system were measured and the yields were 45% and 51% for 2,3-DHBA and 2,5-DHBA, respectively．
