Quality evaluation of Callicarpa kwangtungensis from different origins by HPLC coupled with chemometrics / 中草药

ABSTRACT

Objective: To establish HPLC fingerprints of Callicarpa kwangtungensis from different origins, which can be used in the evaluation for its quality control. Methods: The fingerprints of 15 batches of C. kwangtungensis were further evaluated by chemometrics methods. The similarity analyzed with "Similarity Evaluation System for Chromatographic Fingerprint of Chinese Materia Medica 2004A", and hierarchical clustering analysis (HCA) and principal component analysis (PCA) were performed by SPSS 19.0. Results: There were 12 common peaks, and the similarity degrees of 15 batches of samples were more than 0.644, and showed that all the samples from different origins were of good consistency. The samples were divided into four clusters by HCA. The result of PCA showed that the three factors were chosen, the quality of samples could be evaluated basically. According to the composite score, the quality of C. kwangtungensis from different origins, Hunan Huitong, Guangxi Guilin, Jiangxi Wuning, Jiangxi Nanchang, Jiangxi Pingxiang, and Jiangxi Yichun were better than others. Conclusion: The method is simple, reproducible, and reliable, than it can be used for quality control and evaluation of C. kwangtungensis from different origins.
