Objective: For hygienic supervision, we have developed a method to determine fenfluraminein diet tea by high pressure liquid chromatography (HPLC ). Mothods: It includes water extraction, purifywith C18 column (Solid Phase Extraction) and analysis fenfluramine by HPLC. Results: To optimize thechromatographic condition, we found the methanol mainly controls the retention time of fenfluramine and triethylamine restrains the absorption between the analyze and column cartridge. The linear range of fenfluramineis 0. 2~2μg. While the concentration of fenfluramine in diet tea is between 25μg/ml and 75μg/ml, the average recovery is 93. 8 %. Conclusion: It's an easy, accurate method to analyses the content of fenfluramine indiet tea.
