| Sumario: | To evaluate the important <i>Vitis amurensis</i> germplasm, the quality characteristics and anthocyanin profiles of the ripe berries of 20 <i>V. amurensis</i> grapes and 11 interspecific hybrids in two consecutive years were analysed. Compared with the <i>V. vinifera</i> grapes, <i>V. amurensis</i> grapes had small berries with low total soluble solids and high titratable acids, and were richer in phenolic compounds except for flanan-3-ols in their skins but had lower phenolic contents in their seeds and showed lower antioxidant activities. An outstanding feature of the <i>V. amurensis</i> grapes was their abundant anthocyanin contents, which was 8.18-fold higher than the three wine grapes of <i>V. vinifera</i>. The anthocyanin composition of <i>V. amurensis</i> was characterized by an extremely high proportion of diglucoside anthocyanins (91.71%) and low acylated anthocyanins (0.04%). Interestingly, a new type of speculated 3,5,7-<i>O</i>-triglucoside anthocyanins was first identified and only detected in <i>V. amurensis</i> grapes and hybrids. Based on the total phenolic and anthocyanin characteristics, <i>V. amurensis</i> grapes were set apart from <i>V. vinifera</i> cultivars and the interspecific hybrids, for the same qualities, fell between them, as assessed by principal component analysis. |
