HPLC-ELSD测定甘遂及其制剂控涎丸中大戟二烯醇的含量
摘要
目的:建立甘遂及其制剂控涎丸中大戟二烯醇的含量测定方法。方法:色谱柱为Dikma Diamonsil C18柱(4.6 mm×250 mm
5μm)
流动相甲醇-水(99∶1)
流速1.0 mL.min-1
检测器蒸发光散射检测器
柱温35℃。结果:大戟二烯醇在进样量为1.04~20.80μg(r=0.999 6)
进样量的常用对数值与峰面积的常用对数值呈良好的线性关系
平均回收率97.53%
RSD 2.56%
另外对10批甘遂饮片和5批控涎丸进行了测定。结论:所建立的方法简单、准确、重复性好
可用于测定甘遂及其制剂控涎丸中大戟二烯醇的含量。
Abstract
Objective:To establish a HPLC method for the content determination of euphol in slices of E.kansui and its preparation Kongxian Pills.Method:HPLC-ELSD was carried out on a Dikma Diamonsil C18 column(4.6 mm × 250 mm
5 μm)with methanol-water(99∶ 1) as the mobile phase
the flow rate was 1.0 mL.min-1
and the detector was evaporative light-scattering detector(ELSD).The column temperature was set at 35 ℃.Result:The calibration curve was linear in the range of 1.04-20.80 μg(r = 0.999 6)
the average recovery was 97.53% with RSD of 2.56%.The content of euphol in ten batches of slices of E.kansui and five batches of Kongxian Pills were determined.Conclusion:The method is simple
accurate and reproducible
and it can be used to determine the content of euphol in slices of E.kansui and Kongxian Pills.
