RATIONALE A series of dietary important regioisomeric chlorogenic acids were investigated by ion mobility mass spectrometry (IM-MS). The existence of prototropic isomers separated in the drift dimension was observed and investigated further using tan

Direct infusion MS n and MALDI-TOF-mass spectrometry were applied for characterizing thearubigins isolated from black tea. Components of the so-called SII fraction of thearubigins obtained through caffeine precipitation were studied exclusively. New

Thearubigins are the most abundant phenolic pigments found in black tea, produced by enzymatic oxidation of green tea flavan-3-ols in tea fermentation of until recently unknown composition. In this study electrospray ionization tandem LC-MS(n) experi

Thearubigins are the most abundant pigments found in black tea, comprising polyphenolic oxidation products, whose composition and chemical nature have remained unresolved until recently. In the course of studying the mechanism of thearubigin formatio
