摘 要:目的:建立同时测定淫羊藿样品中淫羊藿苷、朝藿定A、朝藿定B、朝藿定C含量的HPLC方法,为完善淫羊藿市售药材及饮片的质量评价提供参考。方法:采用高效液相色谱法,以Agilent C18(4.6 mm×250 mm,5μm)为色谱柱,乙腈-水为流动相进行梯度洗脱,体积流量1.0 mL/min,柱温25℃,检测波长270 nm。结果:淫羊藿苷、朝藿定A、朝藿定B、朝藿定C分别在0.0800~1.60μg、0.0175~0.350μg、0.0775~1.55μg、0.233~4.66μg(r≧0.9995)范围内呈良好的线性关系,平均加样回收率分别为96.5%、97.4%、97.9%、97.4%,RSD分别为1.3%、1.5%、1.0%、1.8%。结论:所建立的方法简便、准确、重复性好,可以为朝鲜淫羊藿及市售淫羊藿质量评价提供参考。Objective:To establish an HPLC method for simultaneously determining the icariin,Epimendin A,Epimendin B and Epimendin C contents in Epimedium koreanum Nakai and to provide the quality evaluation for the commercially available Epimedium koreanum Nakai herbs.Method:Agilent C18(4.6 mm ×250 mm,5 μm) column in an oven at 25 ℃ was needed with the mobile phase including acetonitrile-water.The flow rate was 1.0 mL/min with a UV detector at 270 nm.Result:The linear range of icariin was 0.0800 ~ 1.60 mg/mL(r = 0.9999) and the average recovery was 96.5%,RSD 1.3%.The linear range of Epimendin A was 0.0175 ~ 0.350 mg/mL(r = 0.9998) and the average recovery was 97.4%,RSD 1.0%.The linear range of Epimendin B was 0.0775 ~ 1.55 mg/mL(r = 0.9999) and the average recovery was 97.9%,RSD 1.0%.The linear range of Epimendin C was 0.233 ~ 4.66 mg/mL(r = 0.9995) and the average recovery was 97.4%,RSD 1.8%.Conclusion:The method appeared to be simple,accurate and reliable,and can provide the basis for Korean Epimedium's quality evaluation.
