Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) as a new valuable technique has been used for qualitative screening of anthocyanins in wine and grape samples from Vranec and Merlot variety. For that purpose, different MALDI matrices have been tested, such as α-cyano-4-hydroxycinnamic acid, sinapic acid, 2,5-dihydroxybenzoic acid (2,5-DHB), and C70 fullerene. It was observed that 2,5-DHB was superior with respect to all the matrices used in the study. Furthermore, fullerene was, for the first time, tested and used as a possible matrix for MALDI-TOF-MS identification of anthocyanins in wine and grape samples. The results obtained showed identification of aglycone forms of anthocyanins only, since the higher laser energy applied for ionization of the fullerene molecules led to great deal of fragmentation of the sugar moiety from glucosides, acetylglucoside, and p-coumaroylglucoside groups from the corresponding anthocyanin molecules. Additionally, liquid chromatography/electrospray ionization mass spectrometry has also been applied for anthocyanin characterization.

    • ...It is necessary to point out that the analysis of plant and food phenolics comprises not only rather simple compounds that are readily extracted and analyzed by HPLC, but also polymers (Quideau et al, 2011), including reaction (eg, oxidation) products, that can prove difficult to extract, to elute from the chromatographic stationary phases, and/or to characterize (Fanali et al, 2011; Ivanova et al, 2011; Kusznierewicz et al, 2011; Andersen and Jordheim, 2010; Tarascou et al, 2010)...
