Study characterized anthocyanins in Marselan wines, suggesting reliable markers for vintage and origin differentiation.
A targeted UPLC-MS/MS method was developed for the comprehensive characterization of 58 anthocyanins and their derivatives (A&D) in Marselan wines. Significant differences among vintages were observed for 12 compounds, with acetylated anthocyanins and pyranoanthocyanins emerging as potential vintage markers. Multi-vintage analysis revealed a pronounced decline in total A&D during aging, accompanied by an increasing proportion of pyranoanthocyanins. Geographical comparison indicated that the A&D profiles clearly discriminated wines from distinct regions (Ning xia, Hebei, Xinjiang), whereas subregional distinction within Ningxia was limited. Multivariate models, particularly SVM, achieved high accuracy at the regional level (> 96%), confirming the potential of A&D fingerprints as robust markers for vintage differentiation and regional traceability of Marselan wines.
