Quantification of anthocyanosides in grapes by QuEChERS and biphenyl-UHPLC tandem mass spectrometry

Abstract

In this study, the QuEChERS and UHPLC-MS/MS method using a biphenyl stationary phase was developed and applied for the rapid separation of 12 anthocyanosides in grapes. Efficient separation was achieved for a wide range of mono- and un-glycosylated anthocyanosides. The linear ranges of the target anthocyanosides were 0.5–500 ng mL −1 . The intra- and inter-day precisions were both below 11.8%. Anthocyanosides in grapes from different sources were successfully quantified. Thus, the developed QuEChERS and UHPLC-MS/MS method provide an attractive alternative for the quantification of anthocyanosides in grapes.
