目的：建立高效液相色谱法测定一点红中克氏千里光碱含量的方法。方法：用Kromasil RP-C18色谱柱（4.6 mm ×250 mm,5μm）,流动相为乙腈-水-磷酸-三乙胺（15∶85∶0.1∶0.4）,检测波长为220 nm。结果：克氏千里光碱在10.04～200.80μg· mL-1范围内与峰面积呈良好线性关系（r＝0.9998）,平均加样回收率为96.34％,RSD为1.80％（n＝6）。结论：此法快速、简便,专属性好,可用于一点红药材中克氏千里光碱的限量检查,为2015年版《中国药典》拟增订药材一点红的质量控制奠定基础。
Objective：To establish an HPLC method for the determination of senkirkine in Herba Emiliae.Methods：The detection was performed on a Kromasil RP-C18 column（4.6 mm ×250 mm,5 μm） at UV wavelength of 220 nm.The mobile phase consisted of acetonitrile, water, phosphoric acid and triethylamine （15∶85∶0.1∶0.4 ）.Results： The calibration curve was linear in the range of 10.04-200.80 μg· mL-1 of senkirkine （ r=0.9998 ）.The average recovery was 96.34% with RSD of 1.80% （ n=6 ）.Conclu-sion：The HPLC method is simple , rapid and accurate for determining senkirkine in Herba Emiliae which can be used for limit detec-tion of senkirkine in Herba Emiliae.The developed method was served for the quality evaluation of Herba Emiliae.
