摘  要:目的:建立了反相离子对色谱法测定益母草中盐酸益母草碱含量的方法。方法:Agilent SB—C18柱(4.6mm×250mm,5μm);流动相:乙腈-0.4%辛烷磺酸钠的0.1%磷酸溶液(24:76);检测波长:277nm;流速:1.0mL·min-1。结果:盐酸益母草碱进样量在0.02866~1.433μg范围内呈良好的线性关系,平均回收率为98.0%,RSD为0.6%。结论:此方法简便、灵敏度高,重现性好,可用于益母草的质量控制。Objective: A method was developed for determination of leonurine hydrochloride in Herba Leonuri by reversed-phase ion-pair chromatography. Methods: The separation was performed on an Agilent SB-C18 column (4.6 mm ×250 mm,5μm) with acetonitrile-0. 4% sodium octanesulfonate of 0. 1% phosphoric acid solution (24: 76) as mobile phase at a flow rate of 1.0 mL·min-1 The detection wavelength was 277 nm. Results: There was a good linear relationship with the range of 0. 028 66-1. 433μg. The average recovery was 98.0% ( RSD =0. 6% ) . Conclusion: The method is simple, sensitive and reliable, it can be used as quantitative analysis method for Herba Leonuri.
