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
5 μm)
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1.04~20.80 μg( 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.
