HPLC法测定复脉灵胶囊中盐酸麻黄碱及盐酸伪麻黄碱含量
Determination of Ephedrine Hydrochloride and Pseudoephedrine Hydrochloride in Fumailing Capsules by HPLC
【摘要】 目的:建立复脉灵胶囊中盐酸麻黄碱、盐酸伪麻黄碱的含量测定方法。方法:采用HPLC法,流动相:乙腈-水-磷酸-三乙胺(3:97:0.1:0.1);色谱柱:Aglient TC-C18(250 mm×4.6 mm,5μm);检测波长:205 nm;流速:1.2 ml·min-1;柱温:室温结果:盐酸麻黄碱的进样量在0.187~0.937μg范围内具有良好的线性关系(r=0.999 7),平均回收率为99.26%,RSD为2.70%(n=6);盐酸伪麻黄碱的进样量在0.226~1.130μg范围内具有良好的线性关系(r=0.999 7),平均回收率为98.77%,RSD为2.21%(n=6)。结论:该方法操作简便、灵敏度高、结果准确,可作为复脉灵胶囊中盐酸麻黄碱、盐酸伪麻黄碱的含量测定方法。
【Abstract】 Objective:To establish a method for the determination of ephedrine hydrochloride and pseudoephedrine hydrochloride in Fumailing capsules.Method:Ephedrine hydrochloride and pseudoephedrine hydrochloride in the capsules was determined by HPLC on an Aglient TC-C18 column(250 mm×4.6 mm,5μm),the mobile phase consisted of acetonitrile-water-phosphoricacid-triethylamine (3:97:0.1:0.1) with a flow rate of 1.2 ml·min-1,the detection wavelength was 205 nm and the column temprature was room temprature. Result:The content of ephedrine hydrochloride had a good linearity within the range of 0.187-0.937μg(r=0.999 7),the average recovery was 99.26%and RSD was 2.70%(n=6).The content of pseudoephedrine hydrochloride had a good linearity within the range of 0.226-1.130μg(r=0.999 7),the average recovery was 98.77%and RSD was 2.21%(n=6).Conclusion:The method is simple,reproducible and accurate,and it can be used in the content determination of ephedrine hydrochloride and pseudoephedrine hydrochloride in Fumailing capsules.
