“…HPLC-MS n has been confirmed to be an ideal tool for analyzing the natural plant secondary metabolites, owing to that it can provide affluent multistage fragment information for compounds with collision-induced dissociation (Chen, He, Mao, Sun, & Pan, 2009;Chen, Li, Sun, Pan, & Schlunegger, 2008a;Sun, Wu, & Pan, 2009;Sun, Zhu, Hu, Wang, & Pan, 2010). Therefore, in our study, high performance liquid chromatography-photo diode array detectionelectrospray ionization tandem mass spectrometry (HPLC-DAD/ ESI-MS n ) technique was employed to identification of the antioxidative components in L. chinensis fruits.…”
