Rapid UPLC-ESI-MS/MS method for the analysis of isoflavonoids and other phenylpropanoids

► A rapid UPLC-MS/MS method for the quantification of isoflavonoids was developed. ► 26 compounds were analyzed simultaneously in a single 17 min run. ► 14 compounds out of the set of 26 analytes were quantified in mung bean sprouts. ► No preconcentration was needed to quantify the analytes in plant material. ► Organic solvent consumption was substantially reduced compared to HPLC.
