ABSTRACT
5-Alk(en)ylresorcinols in rye, wheat, spelt, and barley have been characterized by high-performance liquid chromatography coupled to atmospheric pressure chemical ionization multistage mass spectrometry (HPLC-APcI-MS n ) for the first time. Among the 29 compounds analysed, several major and minor C15, C17, C19, C21, C23, and C25-substituted resorcinols with saturated, monoenoic, dienoic, and/or oxygenated side-chains were characterized by their specific fragmentation patterns in collision-induced dissociation experiments. Additionally, a C27:0 homologue, which has probably been overlooked in previous studies based on HPLC alone, was detected in all cereals analysed. Furthermore, we provide tentative evidence for the occurrence of alkylresorcinols with triolefinic side-chains, which have, to our knowledge, so far not been reported in any cereal species.
