摘要/Abstract

摘要： 目的建立高效液相色谱法测定麝香追风膏中盐酸麻黄碱的含量。方法采用高效液相色谱法,色谱柱为Welch极性乙醚连接苯基柱（5 µm,250 mm×4.6 mm）,流动相为甲醇-0.092%磷酸溶液（含0.02%二正丁胺和0.04%三乙胺）（1.5：98.5）,检测波长210 nm,流速1.0 mL·min^-1,进样量10 µL。结果盐酸麻黄碱在1.66×10^-4~0.244μg范围内呈良好的线性关系,r=0.999 9,平均回收率为101.8%,RSD为1.2%。结论采用本方法测定麝香追风膏中盐酸麻黄碱含量,准确、方便、专属性强,可用于麝香追风膏的质量控制。

Abstract: Objective To determine the content of ephedrine hydrochloride in Shexiangzhuifeng ointmen by HPLC. Methods HPLC with Welch polar ether linked phenyl column (5 µm, 150 mm×4.6 mm) was employed by using methyl cyanide-0.092% H₃PO₄(0.04% triethylamine and 0.02% dibutylamine) (1.5:98.5) as the mobile phase. The flow rate was 1.0 mL·min^-1. The detection wavelength was set at 210 nm. The sample size was 10 µL. Results Ephedrine hydrochloride was in good linear relationship within the rage of 1.66×10^-4~0.244 µg, r=0.999 9. The mean recovery rate was 101.8% and RSD was 1.2%. Conclusion The HPLC method established here for analyzing the ephedrine hydrochloride in Shexiangzhuifeng ointmen is accurate, convenient and specific, which can be used for the quality control (QC).
