Objective: To study on the changes of chemical composition before and after processing of Farfarae Flos by HPLC fingerprint
similarity evaluation
cluster analysis(CA) and principal component analysis(PCA). Method: HPLC-DAD was employed to establish the fingerprints of different processed products of Farfarae Flos from 10 areas.The similarity evaluation
CA and PCA were used to analyze the quality and the changes in composition of different processed products of Farfarae Flos. Result: The common mode of HPLC characteristic chromatographic profile of different processed products was established
the similarities of raw products
honey-fried products and Glycyrrhizae Radix et Rhizoma-fried products were 0.867-0.991
0.785-0.979
0.785-0.980
respectively.Different processed products were divided into four categories by CA
and the results were similar with the similarity evaluation
indicating that the different processed products from different areas had a certain similarity and stability.PCA result screened 2 principle components with accumulative contribution rate of 74.230%
and obtained the related components group
at the same time
the comprehensive score of these processed products from different areas showed that the components group was stable in different processed products of Farfarae Flos. Conclusion: HPLC fingerprint combined with similarity evaluation
CA
PCA can systematically evaluate the quality of processed products of Farfarae Flos
which can provide reference for evaluation of processed products of other Chinese medicines.
