  • Title: Screening of Anthocyanins and Anthocyanin-Derived Pigments in Red Wine Grape Pomace Using LC-DAD/MS and MALDI-TOF Techniques.
    Author: Oliveira J, Alhinho da Silva M, Teixeira N, De Freitas V, Salas E.
    Journal: J Agric Food Chem; 2015 Sep 09; 63(35):7636-44. PubMed ID: 25912410.
    Abstract:
    Two phenolic extracts were made from a red wine grape pomace (GP) and fractionated first by sequential liquid-liquid extraction with organic solvents. The aqueous fraction was fractionated by low-pressure chromatography on Toyopearl HW-40 gel and on C18. Different fractions were obtained by sequential elution with aqueous/organic solvents, and then analyzed by liquid chromatography and mass spectrometry (LC-DAD/MS and MALDI-TOF). Over 50 anthocyanin-based pigments were detected by LC-DAD/MS in GP, mainly pyranoanthocyanins including A- and B-type vitisins and methylpyranoanthocyanins. The presence of oligomeric malvidin-3-O-coumaroylglucoside-based anthocyanins was also detected in GP using both LC-DAD/MS and MALDI-TOF.
