Abstract: A modern HPLC analysis method was developed for the determination of seven major ginsenosides in 12 kinds of Panax quinquefolium. L. Their chromatographic fingerprints were established by HPLC. Separations and determinations were carried out by linear gradient elution under following conditions: Alltima C18 (250mm×4.6mm, 5μm) column, acetonitrile-0.05% phosphoric acid solution as mobile phase, detection length of UV at 203nm, flow-rate of 1.2ml/min, column temperature of 35 ℃. The obtained results indicated that the developed method was simple, accurate and reliable for the determination of seven ginsenosides in Panax quinquefolium. L with a good linearity with the recovery ranges of 94.1%~97.9%. Hierarchical clustering analysis was performed and the similarity of the HPLC chromatograms was analyzed for the research of fingerprints and classificationo f Panax quinquefolium.L samples.
