摘要
目的:建立亲水作用色谱-蒸发光散射检测器联用测定益母草中盐酸水苏碱含量的方法。方法:采用HILIC柱(250mm×4.6 mm,5μm);乙腈-0.2%冰醋酸溶液(80∶20)为流动相;Alltech2000蒸发光散射检测器:漂移管温度80℃,气体流速2.0 L.min-1;流速0.5 mL.min-1。结果:盐酸水苏碱进样量在0.536～10.713μg范围内呈良好的线性关系,平均回收率为101.9%,RSD为1.4%。结论:此方法简便、灵敏度高,重现性好,可用于益母草的含量测定。
Objective： To establish a HILIC-ELSD method for determination of Stachydrine hydrochloride in Herba Leonuri.Method： The separation was performed on a HILIC column（250 mm ×4.6 mm,5 μm）with acetonitrile-0.2% glacial acetic acid solution（80∶ 20）as mobile phase at a flow rate of 0.5 mL·min-1.An Alltech 2000 evaporative light-scattering detector（ESLD）was used as detector with gas flow rate of 2.0 L·min-1 and drift tube temperature of 80℃.Results： There was a good linear relationship with the range of 0.536–10.713 μg.The average recovery was 101.9%（RSD = 1.4%）.Conclusion： The method is simple,sensitive and reliable,it can be used as quantitative analysis method for Herba Leonuri.
