OBJECTIVE: To establish a method for the content determination of kaempferol in Kaempferia galanga. METHODS: HPLC was performed on the column of Diamonsil ODS2 C18 with mobile phase of methanol-0.4% Phosphoric acid solution at a flow rate of 1 ml/min, detection wavelength was 367 nm, column temperature was 30℃, and injection volume was 10 μl. RESULTS: The linear range of kaempferol was 0.001 58-0.158 mg/ml; RSDs of precision, stability and reproducibility tests were lower than 3%; recovery was 95.52%-99.32% (RSD=1.47%,n=6). CONCLUSIONS: The method is simple, accurate and reproducible, and can be used for the content determination of kaempferol in K. galanga.
