Preliminary Study on HPLC Fingerprint of Artichoke(Cynara scolymus L.) Leaves

[Objective] To establish the HPLC fingerprint of Cynara scolymus L.leaves extracts.[Methods] The Cynara scolymus L.leaves were extracted with 70% ethanol(V/V) and analyzed by HPLC,the chromatographic condition were as follows:C18 column(4.6 mm×250 mm,5 μm),mobile phases of acetonitrile-0.5% acetic acid-water,gradient elution,detection wavelength of 330 nm.[Results] 14 batches of the extracts were analyzed by Chinese Medicine Chromatographic Fingerprint Similarity Evaluation software,and 15 peaks were identified as fingerprint.The common mode of Cynara scolymus L.leaves extracts was preliminary established.[Conclusion] The fingerprint established by this method will provide basic data for the quality control of artichoke leaves.
