摘　　要：目的:建立苦豆草药材的质量标准。方法:采用TLC法对苦豆草药材进行定性鉴别;用HPLC法测定氧化苦参碱和槐定碱的含量。结果:薄层色谱图显示,氧化苦参碱和槐定碱与其他生物碱分离效果良好,可以用于苦豆草药材的鉴别;高效液相色谱中,氧化苦参碱和槐定碱分别在25.104～125.52μg和22.824～114.12μg范围内线性关系良好,平均加样回收率(n=9)分别为96.2%和95.9%。结论:所建立的方法可准确地进行定性、定量分析,可用于苦豆草药材的质量控制。Objective：To establish the quality standard of Herba Sophora Alopecuroides . Methods： The TLC and HPLC methods were used for qualitative identification and quantitative determination of oxymatrine and Sophridine. Cis column （4. 6 mm ×250 mm,5 μm） was used. The mobile phase consisted of 0. 05 mol · L^-1K2 H2 PO4 solution-acetonitrile （90： 10） （2.0 mL · L^-1 triethylamine ） . The UV detective wavelength was 205 nm. Results： The identified characteristics of Oxymatrine and Sophridine were distinct and Her- ba Sophora Alopecuroides could be identified by TLC. In the system of HPLC, the linear range for the content of Oxymatrine and Sophridine were as the of 25. 104 - 125.52 μg （r =0. 9991） and 22. 824 ~ 114. 12 μg （r =0. 999 7）. Conclusion： The method can be used for the quality control of Herba Sophora Alopecuroides.
