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.
