Antocyanin comples assessment in red grape cultivars from western foothill-seaside region of the piedmont Crimea
The publication provides data obtained by HPLC and comparative analysis on the qualitative and quantitative composition of the antocyanin complex of European (Merlot, Cabernet-Sauvignon) and selection grape cultivars (Antey Magarachsky, Krasen, Golubok) cultivated in the Bakhchisarai region of the Republic of Crimea. We have established similarities between the skin anthocyanin complex of Merlot, Cabernet-Sauvignon and Antey Magarachsky varieties and that of Krasen and Golubok varieties. In the first case, the anthocyanins complex was up to 42-48% composed of malvidin-3-O-β-D-glycoside, in the second, it was up to 63-72% composed of malvidin-3,5-O-β-D-diglycoside. We identified peculiarities of the qualitative and quantitative composition of the anthocyanin complex of the examined grape varieties. The distinctive feature of Antey Magarachsky was the presence of trace amounts of peonidin-3,5-O-β-D-diglycoside.
