Özet
Phenolic compounds in white wines produced by cv. Shesh i bardhe, and red wines produced by cv. Vlosh, two native grape cultivars of Albania, was investigated by using Liquid Chromatography-Diode Array Detection-Electrospray Ionization-Tandem Mass Spectrometry (LC-DAD-ESI-MS/MS). A total of 32 phenolic compounds including phenolic acids, flavan-3-ols, flavonols, and stilbenes were identified in both wines, with flavanols the main family contributing to total phenolics, from 45.3% to 89.9%. Gallic acid, procyanidin dimer, and trans-caftaric acid were found main compounds in both wines. Significant differences have been found depending on the region and vintage. It was observed that total phenolic content in wines from the Durresi region stands higher compared to wines originating from the Tirana region. As a result, significant variations were found among the cultivars in terms of the phenolic profiles, and Shesh i bardhe wines phenolic compounds were much higher than the Vlosh wines. Novelty impact statement This is the first study on the phenolic compounds of the white wine from Shesh i bardhe grape cv. and red wine produced by Vlosh cv. in Albania. The presence of 30 phenolic compounds was identified through LC-DAD-ESI-MS/MS, with flavanols the main family contributing to total phenolics, from 45.3% to 89.9%. Gallic acid, procyanidin dimers, as well as resveratrol were found in both wines.
