Comparative flavan-3-01 composition of seeds from different grape varieties

[EN]The flavanol composition of the seeds of 17 varieties of grape cultivated in the main wine-producing areas of Castilla-Leon (Spain) was studied. Twenty-seven different flavan-3-01s of procyanidin type were found, but no prodelphinidins were detected. Minor amounts of four hydrolyzable tannins we...
