HPLC指纹图谱结合化学计量学评价不同产地广东紫珠药材的质量

目的建立不同产地广东紫珠Callicarpa kwangtungensis的HPLC指纹图谱,用于广东紫珠药材质量的评价。方法采用中药色谱指纹图谱相似度评价系统(2004A版)对5省15批不同产地的广东紫珠药材的HPLC指纹图谱进行相似度评价,并使用SPSS 19.0软件进行聚类分析和主成分分析。结果选取了12个色谱峰作为指纹图谱共有峰,15批样品的相似度计算结果均大于0.900,说明各产地的药材有较好的一致性;通过聚类分析可将15批样品聚为4类;主成分分析用3个主成分对广东紫珠药材进行综合评价,综合得分结果显示,湖南会同、广西桂林、江西武宁、江西南昌、江西萍乡、江西宜春的广东紫珠药材在所有样品中的综合得分位于前6名。结论本实验建立的广东紫珠质量评价方法操作简便,重复性好,结果可靠,可以用于广东紫珠药材的质量控制和评价。

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

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.
