摘要

目的: 建立测定牛蒡草主要活性成分绿原酸含量的方法

并比较不同产地牛蒡草绿原酸的含量差异

为牛蒡草质量控制提供依据。方法: 采用Agilent C18色谱柱(4.6 mm×150 mm

5 μm)

以乙腈-0.4%磷酸水溶液(8∶92)为流动相

检测波长327 nm

体积流量1.0 mL·min-1

柱温30 ℃

进样量10 μL

外标法定量。结果: 绿原酸得到良好分离

在0.041 8 ~4.18 μg与峰面积积分值呈良好的线性关系

平均加样回收率为100.3%。结论: 该方法简便、准确、分离度良好

为牛蒡草的质量控制提供了依据。

Abstract

Objective: To establish an HPLC method to determine the content of chlorogenic acid in Arctium lappa

and to compare the content in A. lappa which from different regions. Method: HPLC was performed on an Agilent C18 analytical column(4.6 mm×150 mm

5 μm)at 30 ℃ with acetonitrile-0.4％ phosphoric acid solution as the mobile phase; the detection wavelength was 372 nm and the flow rate was 1.0 mL·min-1. Result: Chlorogenic acid was separated perfectly

and its linearity was good in ranges of 0.041 8-4.18 μg. The average recovery was 100.3%. Conclusion: The validated method is simple

accurate

and had a good resoulution.It can be able to provide the basis for the quality control of A. lappa.
