A strategy of EIC-MS coupled with diagnostic product ions analysis for efficient discovery of new hydroxylated polymethoxyflavonoid glycosides from the leaves of Murraya paniculata L. using HPLC-DAD-MS/MS
Abstract
Hydroxylated polymethoxyflavonoid glycosides (OH-PMFGs) are a rare kind of highly methoxylated flavone glycosides, which demonstrate many health-promoting bioactivities. Here we aim to identify OH-PMFGs from the leaves of Murraya paniculata using EIC (extracted ion chromatogram)-MS coupled with diagnostic product ions (DPIs) analytical method. Respective DPIs for
