摘 要:目的:建立HPLC法测定盐酸西替伪麻缓释片中盐酸伪麻黄碱和盐酸西替利嗪的含量。方法:色谱柱为Hypersil ODS C18柱(4.6mm×250mm,5μm),流动相为乙腈-0.3%冰醋酸溶液-0.3%庚烷磺酸钠溶液(45:30:25),流速为1.0mL·min^-1,检测波长为244nm。结果:盐酸伪麻黄碱在360~1800mg·L^-1(r=1.000)范围内线性关系良好,平均回收率为99.3%(n=5),RSD为0.4%;盐酸西替利嗪在14~72mg·L^-1(r=1.000)范围内线性关系良好,平均回收率为98.7%(n=5),RSD为0.6%。结论:该方法简便、准确、快速,可同时测定两组分的含量。Objective:To establish an HPLC method for determination of Cetirizine Hydrochloride and Pseudoephedrine Hydrochloride Sustained-release Tablets. Methods: The analytical column was Hypersil ODS C18 column(4. 6 mm × 250 mm,5μm)and the mobile phase was acetonitrile -0. 3% glacial acetic acid -0. 3% sodium heptanesulfonate (45: 30: 25) at a flow rate of 1.0 mL·min^-1. The UV detection wavelength was at 244 nm. Results: The linearity was good for Pseudoephedrine Hydrochloride within the range of 360 1 800 mg · L^-1 (r =1. 000) ,the mean recovery was 99. 3% (n =5), RSD =0. 4% ; The linearity was good for Cetirizine Hydrochloride within the range of 14 -72 mg · L^-1 (r = 1. 000) ,the mean recovery was 98.7% (n =5), RSD =0.6%. Conclusion: The method is simple and rapid for determination of two components in the drug.
