| Abstract: | Objective To establish a method of fuzzy pattern recognition of fingerprints of P. cocos.Methods The measurement condition used was as follows:Phenomenex Luna C 18 (4.6 mm×150 mm, 5 μm),the mobile phase∶acetonitrile-0.05%phosphoric acid (64∶36,v/v),flow-rate:1.0 mL·min -1 ,detector:PDA,wave-length:242 nm, the temperature :25 ℃.The cosine of the angle was employed to evaluate the similarity of common peaks of fingerprints of P.cocos.The fuzzy pattern recognition of fingerprint was analyzed by computer.Results The result conform with those of the morphological examination.Conclusion The proposed method could be used for determining the fingerprint of Traditional Chinese medicine qualitatively and quantitatively,and have a better steaility and repeatability. |
