Abstract:
Eight compounds from six Chrysanthemum morifolium cv. 'Hangju' were determined and multivariate statistics, including principle component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) were used to investigate the potential damaging effect of sulfr-fumigating process. Meanwhile, S, Mn, Fe, Cu, Pb were also detected by using ICP-MS and ICP-OES. In this study, dramatic chemical changes were found that the contents of flavonoid aglycones remarkably increased while those of glycosides and hydroxycinnamoylquinic acids were significantly reduced. The PCA score plots showed six samples were clearly classified into the non-fumigated and sulfur-fumigated types. And according to VIP > 1, the most important chemical markers were luteolin, apigenin and luteolin-7-O-glucoside which indicated that the extracted three components might have a marked effect on the discrimination among different group samples. And then, it was found that the residue of sulfur of SHJ were significantly higher than NHJ (P < 0.05). The established approach was applied to rapidly discriminate sulfur-fumigated HJ with combining the quantitative chemical analysis and multivariate statistical analysis, and then the result will provide some evidence to evaluat the quality of HJ and control its processing.
