Abstract: A mass spectrometric-based procedure for anthocyanin profiling was set up to distinguish authentic Vitis vinifera from hybrid red grapevine cultivars. 3-O-Monoglucoside and the related acetyl-, p-coumaryl- and caffeoyl-monoglucoside anthocyanins occurred only in Vitis vinifera, whereas 3,5-O-diglucoside and the substituted acetyl-, p-coumaryl-, feruloyl- and caffeoyl-diglucoside anthocyanins were the additional pigments in hybrid grapevines. The procedure was applied expressly to identify red grape cultivars based on the anthocyanin chemo-type determination. In particular, a red grape cultivar, having 3,5-O-diglucoside anthocyanins and a novel class of anthocyanin monoglucosides, such as cyanidin-3-O-, cyanidin-3-O-(6-O-acetyl)- and cyanidin-3-O-(6-O-p-coumaryl)pentoside, was classified as hybrid. A second vine cultivar, characterized exclusively by 3-O-monoglucoside anthocyanins, was included among the Vitis vinifera species. Anthocyanin profiling by mass spectrometry could represent the core of a chemotaxonomic procedure for distinguishing American and European grapevines based on the identification of post-synthetic anthocyanidin modification.
