Abstract
The proanthocyanidin composition of grape skins was studied and compar ed with that of grape seeds. Qualitative and quantitative differences in proanthocyanidin contents were observed between skins and seeds fro m the same variety. Grape seeds were found to have higher amounts of f lavan-3-ol than skins; only procyanidins were found in the former, whi le in the skins prodelphinidins were also present, a predominance of ( +)-catechin being found in their elemental flavan-3-ols.
