Abstract

Hadamard transform atmospheric pressure ion mobility-MS and rapid UHPLC-MS methods were investigated for analysis of closely related isomeric flavonoids and their glycosides using a test set of seven standards. On a time scale of a few minutes, the flavonoid aglycones were all separated by ion mobility, but not by UHPLC. The glycosides were better resolved by IMS but not completely separated by both methods. The results suggest that IMS provides sufficient resolution for separation of isomeric polyphenols such as flavonoids in high-throughput metabolomics studies.
