Resumen
[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 were also present in
the seed extracts of most of the grapes analyzed. All the varieties contained galloyled
flavanols, such that their presence could be considered characteristic of the
grape seed composition. Some proposals concerning the biosynthesis of flavan-
3-01 in the grape seed are also advanced taking into account the compounds found.
