palmatine hydrochloride(peak 9),berberine hydrochloride(peak 10),lovastatin(peak 14). Peaks 7-10 were the exclusive peaks
of Coptis chinensis;peaks 3-6 and 11-13 were the exclusive peaks of bran-fried Fructus aurantii;peak 14 was the exclusive peak
of Monascus purpureus;peak 1 was the common peak of C. chinensis and M. purpureus. Peak 2 and 15 were the common peak of
bran-fried F. aurantii and M. purpureus;peaks 16 and 17 were the common peaks of 6 traditional Chinese medicines. The results of
CA showed that 13 batches of QTXT could be divided into three categories,S2 was clustered into one category,S1,S9,S10 were
clustered into one category,S3-S8 and S11-S13 were clustered into one category. The results of PCA showed that accumulative
variance contribution of the first three principal components was 85.120%. Compared with CA,S1 was further distinguished from
S9 and S10 by PCA. OPLS-DA showed that 7 common peaks with VIP value greater than 1(from large to small)were peak 10
(berberine hydrochloride),peak 9(palmatine hydrochloride),peak 5(hesperidin),peak 11 and peak 8(coptisine hydrochloride),
peak 12 and peak 6 (neohesperidin). The contents of naringin,hesperidin,neohesperidin,berberine hydrochloride,palmatine
hydrochloride and lovastatin measured by QAMS were 40.198-77.552,6.138-13.413,71.823-125.868,11.274-49.951,3.303-
5.367,1.821-3.185 mg/g,respectively. The contents of naringin,hesperidin,neohesperidin,berberine hydrochloride,coptisine
hydrochloride,palmatine hydrochloride and lovastatin measured by external reference method were 41.454-79.976,6.404-13.993,
74.068-129.081,11.627-51.512,5.922-12.020,3.158-5.131 and 1.901-3.325 mg/g,respectively. The deviations of the two methods
(except for coptisine hydrochloride)were all less than 3.00%. CONCLUSIONS The established HPLC fingerprint and the method
of QAMS are simple,accurate and reproducible. Combined with chemical pattern recognition analysis,it can be used for the
quality evaluation of QTXT. Berberine hydrochloride,palmatine hydrochloride and other components may be the markers affecting
the quality of the drug.
