摘要: 目的 建立HPLC测定克感滴鼻液中盐酸麻黄碱的含量。方法 采用ODS柱,以0.01mol/L磷酸二氢钾溶液-乙腈(45:55)为流动相;检测波长为215nm;流速为1.0mL/min。结果 线性范围为40-96μg/mL,平均回收率为96.1%,RSD=1.2%(n=5)。结论 本法简便、快速、准确,可用于本制剂质量控制。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 0.01 mol/L KH2PO4 solution-acetonitrile(40:60).The detection wavelengthwas 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.
