Anthocyanins are naturally occurring polyphenolic plant pigments. To analyze the anthocyanin content of samples, rapid and reliable methods for separation and detection are needed. In this work an LC-DAD-ESI-MS/MS instrument was used to develop a new tandem MS data acquisition strategy for anthocyanin characterization which was subsequently compared to more conventional measurements. It has been shown that the newly developed strategy, multiple reaction monitoring-initiated anthocyanin characterization (MIAC), can successfully be used in anthocyanin analysis and has various advantages compared to some more traditional measurements, such as enhanced selectivity, better signal-to-noise ratio and simplified data evaluation. Furthermore, the number of relevant MS/MS data increased significantly with the MIAC method compared with a more common information dependent MS experiment strategy.
