摘要

Mavrokountoura, a clone of the Mandilaria grape cultivar, was studied for the first time. The morphological characteristics and composition of berries were determined, as well as total phenols and tannins in skins, flesh, and seeds. The skin anthocyanins were identified using HPLC-MS/MS and quantified using HPLC-DAD. Two main anthocyanins were identified as malvidin-3-O-glucoside and malvidin-3-O-(6″-p-coumaroyl)-glucoside. One minor anthocyanin was identified as malvidin-3-O-(6″-acetyl)-glucoside. Glycosides of delphinidin, petunidin, and peonidin were detected in traces. Young Mavrokountoura wine was also studied. Extraction of total phenols from the grape to the young wine amounted to 32%, composing mainly non-tannic phenols. The individual anthocyanin components exhibited different extractability values from the skin to wine, ranging between 10–94%.
