Abstract

This study aimed to characterization of anthocyanins (3-monoglucosides, 3-acetylglucosides, and 3-coumaroylglucosides), pyranoanthocyanins and hydroxyphenyl-pyranoanthocyanins in Vranec wines during aging of three years. The HPLC-DAD–ESI-MSn technique was applied for identification of anthocyanins and derived stable pigments pyranoanthocyanins. All anthocyanins presented mass spectra characterized with two signals, molecular ion M+ and fragment ions [M-162]+, [M-204]+ and [M-308]+ resulting from elimination of glucose, acetylglucose and p-coumaroylglucose moieties, respectively. From the group of pyranoanthocyanins, A-type and B-type vitisins, as well as hydroxyphenyl-pyranoanthocyanins have been determined according to their molecular ions (M+) and characteristic fragments.
