| Sumario: | [EN] The proanthocyanidin composition of grape skins was studied and compared with that of grape seeds. Qualitative and quantitative differences in proanthocyanidin contents were observed between skins and seeds from the same variety. Grape seeds were found to have higher amounts of flavan-3-ol than skins; only procyanidins were found in the former, while in the skins prodelphinidins were also present, a predominance of (+)-catechin being found in their elemental flavan-3-ols. |
