title: A correlation between antioxidant activity and metabolite release during the blanching of Chrysanthemum coronarium L.
abstract: Liquid chromatography tandem mass spectrometry (LCMS/MS)-based metabolite profiling was applied to elucidate the correlation between metabolite release and antioxidant activity during water blanching of Chrysanthemum coronarium L. (CC). Some major metabolites showing differences between fresh CC and blanched CC (BCC) were selected by principal component analysis (PCA) and partial least-square discriminate analysis (PLS-DA) loading plots, and were identified as dicaffeoylquinic acid (DCQA), succinoyl-DCQA, and acetylmycosinol. By PLS regression analysis of the correlation between antioxidant components and effects, candidate antioxidative metabolites were predicted due to strong positive correlations with DCQA and succinoyl-DCQA, and by a relatively weak positive correlation with acetylmycosinol.
