【Abstract】 OBJECTIVE: To develop a method for the determination of ephedrine hydrochloride in kegan nasal drops by HPLC. METHODS: The chromatographic condition included ODS column and the mobile phase consisting of 0. 01mol/L KH2PO4 solution - acetonitrile(40 : 60). The detection wavelength was at 215nm, flow rate at 1. 0mL/min. RESULTS: The calibration curve was linear over the rage of 40 -96μg/mL. The average recovery was 96. 1%. The method precision (RSD% ) was 1. 2% (n =5). CONCLUSION: The method was convenient and accurate for the quality control of the preparation.更多还原
