摘 要:目的:建立RP-HPLC测定盐酸帕罗西汀的含量的方法。方法:色谱柱:Sepax Sapphire C_(18)(4.6 mm×250 mm,5μm),流动相:取醋酸铵3.96 g,加水720 ml使溶解,加乙腈280 ml、三乙胺10 ml,用冰醋酸调节pH值至5.5,流速:1.0 ml/min,检测波长:295nm。结果:盐酸帕罗西汀在为(10~200)μg/ml浓度范围内线性关系良好,r=0.9999。结论:本方法准确、简便、快速,可满足盐酸帕罗西汀含量的测定。Objective: Establishment of RP- HPLC methodology for determination of paroxetine hydrochloride content. Method: The chromatographic column was Sepax Sapphire C18 (4.6 mm×250 mm, 5 μm ), the mobile phase consisted of ammonium acetate (3.96 g), adding water (720 ml), adding acetonitrile (280 ml), and adding ethylamine(10 ml) at flow rate of 1.0 ml/min, detection wavelength was 295 nm. Results: The linear range of Paroxetine hydrochloride was (10~200)μg/ml (r=0.9999). Conclusion: The method was accurate, simple, and rapid. It can be adopted for the determination of the Paroxetine Hydrochloride.
