Objective To investigate the extraction methods for active components from oral ulcer film and optimize the determination methods of active components dexamethasone sodium phosphate and metronazole. Methods Different extraction solvents(methanol, water and 70% methanol aqueous) were applied to extract the active components dexamethasone sodium phosphate and metronazole from oral ulcer film, which contents were quantified by a HPLC method. Results the extraction solvent water had the best efficacy and more simpler compared to the other two solvents. Clotriazole showed a good linear relationship within 5.014 5-200.5800 μg/ml (r=0.999 8), and the average extraction recovery was (104.23±0.63)%, and for dexamethasone sodium phosphate, a good linear relationship was obtained in the range of 0.482-16.328 μg/ml (r=0.9999), and the average extraction recovery was (103.97±1.02)%. Conclusion The water extraction method established in this study was simple and efficient, which showed features of simplicity, accuracy and repeatable.
