Isolation of C30H26O12-Procyanidin B 1 from GrapesThe procyanidins of grapes are dimeric and polymeric dehydrocatechins. Leucocyanidins (5.7.3′.4′-tetrahydroxyflavan-3.4-diols) have not been detected. As well as the procyanidins, a number of crystalline polyphenols is isolated. The yield and constitution of these compounds are given.
