HPLC测定益母草软胶囊中盐酸水苏碱的含量
摘要
目的: 应用高效液相色谱法测定益母草软胶囊中盐酸水苏碱的含量。 方法: 采用Kromasi C18(4.6 mm×250 mm
Objective:An HPLC method was established for determination of stachydrine hydrochloride in Yimucao Soft Capsule. Method: Chromatographic column was Kromasi-C18 with acetonitrile-water (80∶20) as the mobile phase. The detection wavelength was set at 192 nm and flow rate was 1.0 mL·min-1. Result: Stachydrine hydrochloride was separated with a good linearity in the sample size ranges of 2.456-12.280 μg. The average recovery was 98.67%
with RSD 1.39%. Conclusion: The method is simple
specific and reproducible to control the quality of Yimucao Capsule.
