Polyphenols Analysis by Liquid-Mass Spectrometry

Hyphenated Techniques in Grape and Wine Chemistry Edited by Riccardo Flamini 2008 John Wiley Sons, Ltd. ISBN 978-0-470-06187-9 [Pg.81]

Identification and quantification of low molecular weight and volatile phenols is usually performed by Gas Chromatography and Mass Spectrometry (GC-MS). For analysis and structural characterization of more polar compounds such as polyphenols, liquid-phase and Liquid Chromatography Mass Spectrometry (LC-MS) and Multiple Mass Spectrometry (MS/MS and MSn) techniques are used (Niessen and Tinke, 1995 de Hoffmann, 1996 Abian, 1999 Flamini et al., 2007). [Pg.82]

The application of mass spectrometry in the analysis of polyphenolic compounds in biological samples produced excellent results. The coupling of liquid chromatography with mass spectrometry allows for the determination of accurate molecular masses, making it possible to predict the stmcture of an unknown compound. UHPLC-MS (20,22) was used to improve the selectivity of methods, and UHPLC-MS/MS (21,23,24,29,30,32-34) was used to reduce the interference caused by co-eluted components of the analyzed mixture, to track the mass fragmentation of the analytes, and to aid the elucidation of molecular stmctures. [Pg.208]
