Establishment of Fingerprint,Cluster Analysis and Principal Component Analysis of Rhizoma Atractylodes from Different Origin
Objective To establish HPLC fingerprint of Atractylodes chinensis(DC.)Koidz.,and to conduct its cluster analysis and principal component analysis.Methods Fingerprint spectra of 8 common peaks were established for Atractylodes chinensis(DC.)Koidz by using HPLCmethod,and their similarity was calculated.Clustering analysis and principal component analysis(PCA)were performed to compare the results and initially screen out the batches of medicinal herbs with better quality.Results The similarity of 17 batches of medicinal herbs(0.920-0.996)was calculated with fingerprint spectra evaluation software.Meanwhile,the 8 batches of medicinal herbs were divided into four categories by clustering analysis,and the medicinal herbs with the origins of s15 and s16 were comprehensively evaluated as of best quality by PCA.Conclusion The method is accurate,simple and reproducible,so it can be used toContent determination and evaluate the quality of Atractylodes chinensis(DC.)Koidz.
