| Abstract
|
| [Objective] The quality attributes of Paeonia lactiflora from different producing areas were characterized by content of paeoniflorin,characteristic spectra of decoction and paste-forming rate,so as to provide a quality evaluation method for its application of classical prescriptions.[Methods] The content of paeoniflorin in each batch of Paeonia lactiflora was determined by the method of Pharmacopoeia of the 2015 edition;the decoction of medicinal materials was prepared refer to ancient methods,the characteristic spectra were explored and established. The decoction characteristic spectra and paste-forming rate of Paeonia lactiflora from six producing areas were determined,and similarity analysis (SA),hierarchical cluster analysis (HCA) and principal component analysis (PCA) were carried out.[Results] There were six common peaks identified in the characteristic spectra of decoction of Paeonia lactiflora,and the similarity was between 0.829~0.999. All batches of samples can be classified into two groups by HCA and PCA,which were consistent with the results of SA.[Conclusion] In this study,paeoniflorin content,characteristic spectra of decoction and paste-forming rate were taken as the evaluation indicators,and the quality attributes of Paeonia lactiflora from different habitats can be effectively evaluated by chemometrics and component analysis,which has certain application value. |
