Study on the HPLC Fingerprints of Paeonia suffruticosa Cultivated in Chongqing Dianjiang County(Part Ⅱ): Fingerprints of Unshared Paeonia suffruticosa
OBJECTIVE: To establish the standard HPLC fingerprints of unshaved Paeonia suffruticosa cultivated in Dianjiang county so as to provide a new reference basis and technical means for the scientific appraisal and effective control of the quality of P. Suffruticosa. METHODS: 11 batches of original samples of unshaved P. Suffruticosa from Chongqing Dianjiang county were determined by HPLC. The software "Similarity Evaluation System for Chromatographic Fingerprint of TCM" (2004A version) issued by National Pharmacopoeia Committee of China was used for automatic matching, computation of similarities and analysis of chromatograph data. RESULTS: There were 14 common peaks in 11 batches of original samples,and the total peak area of the common peaks accounted for 91.83% of total. The similarity between various samples and the automatically generated reference fingerprints reached above 0.95. CONCLUSION: The reference fingerprints of 11 batches of original samples could be used as the standard fingerprints of unshaved P. Suffruticosa cultivated in Dianjiang county, and their characteristic information of the fingerprints is fully extracted.
