ABSTRACT
AIM:To establish the fingerprint for Cacumen Platycladi (carbonized) by HPLC. METHODS:The column of Lichrospher C 18 (250 mm?4.6 mm 5 ?m)was used. The mobile phase consisted of 0.5‰ trifluoroactic acid-methanol with gradient elution. The detective wavelength was at 375 nm,and the flow rate was 1.0 mL/min. Different habitats were compared by Similarity Evaluation System for Chromatographic Fingerprint of CMM Version 2004A. RESULTS:The fingerprint consisted of 14 common peaks. The mutual mode of HPLC fingerprints was set up and the similarity of the crude drugs was in the range of 0.178-0.963. The standard HPLC fingerprint of Cacumen Platycladi (carbonized) was established too. CONCLUSION:This method is accurate and reliable and provides a scientific basis for the quality control of Cacumen Platycladi (carbonized).
