Abstract:
OBJECTIVE To establish the fingerp rint of decoction pi eces and dispensing granules of Gardenia jasminoides ，to determine the contents of 6 components，so as to evaluate its quality combined with chemical pattern recognition. METHODS High performance liquid chromatography （HPLC）was used. Using geniposide as the reference ，Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）was used to draw the fingerprints of 20 batches of G. jasminoides decoction pieces and 10 batches of G. jasminoides dispensing granules. Similarity evaluation and common peaks identification were conducted. The same HPLC method was adopted to determine the contents of deacetyl asperulosidic acid methyl ester ，geniposide， picrocrocin，rutin，crocin-Ⅰ and crocin- Ⅱ. ORIGIN 9.1 software was used for hierarchical clustering analysis ，and SIMCA 16.0 software was used for principal component analysis （PCA） and partial least squares-discriminant analysis. The differential components affecting the quality of decoction pieces and dispensing granules were screened by taking the variable importance in projection（VIP）value＞1 as the standard. RESULTS There were 24 common peaks for both 20 batches of G. jasminoides decoction piece and 10 batches of G. jasminoides dispensing granules ；a total of 22 common peaks were found in the fingerprints of 30 batches of samples ，and the similarity was not lower than 0.96；six common peaks were identified ，i.e. deacetyl asperulosidic acid methyl ester （peak 2），geniposide（peak 6），picrocrocin（peak 9），rutin（peak 11），crocin-Ⅰ（peak 15），crocin-Ⅱ（peak 17）. Average contents of above 6 components in G. jasminoides decoction pieces were 1.04，57.00，1.30，1.03，9.63 and 0.99 mg/g， respectively；those of G. jasmin oides dispensing granules were 0.96，17.04，0.37，0.27，0.73 and 0.04 mg/g，respectively. PCA results showed that G. jasminoides decoction pieces and G. jasminoides dispensing granules were clustered into respective one category ，which was consistent with results of cluster analysis. There were 9 common peaks with VIP value ＞1， which were 16，14，3，17（crocin-Ⅱ），15（crocin-Ⅰ），18， 22， 2 （deacetyl asperulosidic acid methyl ester） and 21. CONCLUSIONS The estab lished fingerprint and content determination method are simple and reproducible. Combined with chemical pattern recognition ，it can be used to evaluate the quality of decoction pieces and dispensing granules of G. jasminoides . Nine corresponding components represented by peak 16 and so on are the differential components that affect the quality of them.
