ABSTRACT
<p><b>OBJECTIVE</b>To establish the HPLC fingerprint of Angelica polymorpha.</p><p><b>METHOD</b>The 10 batches of A. polymorpha were measured by HPLC with isoimperatorin as a reference substance and the chromatographic experients were performed on Kromasil 100A C18 column (4.6 mm x 250 mm, 5 microm), eluted with acetonitrile and water as mobile phase in gradient mode. The flow rate was 1.0 m x min(-1) and the detection wavelength was 254 nm.</p><p><b>RESULT</b>The common mode of the HPLC fingerprints were set up. There were 8 common peaks in the fingerprint of 10 samples, and the similarity of the 10 samples was more than 0.9.</p><p><b>CONCLUSION</b>The method is simple, accurate and have a good reaptability. The quality of A. polymorpha can be controlled effectively by the HPLC fingerprint.</p>
