Diverse Health Effects of Proanthocyanidins

The flavan-3-ols (catechins), flavan-4-ols/flavan-3,4-diols (leucoanthocyani-dins), A-type proanthocyanidins, B-type proanthocyanidins including the [Pg.24]

The pine bark and grape seeds contain the flavonoids oligomeric proan-thocyanidins (OPCs), which offer antioxidant protection against heart diseases and cancers. [Pg.25]

Numerous health benefits have been epidemiologically associated with these proanthocyanins. Significant benefits of proanthocyanins might be their antioxidant protection especially against age-related diseases such as heart diseases and cancers. [Pg.25]

Proanthocyanidins is a class of flavonoids. Proanthocyanidins are derived from the flavonoids oligomeric proanthocyanidins (OPCs) and therefore proanthocyanidins have been formerly called condensed tannins. Moreover, all proanthocyanidins have similar structures and the only differences are slight changes in the shape and attachments of the polyphenol rings. The diverse proanthocyanidins could always be found together, ranging from a proanthocyanidin unit to complex molecules with many linked units as the oligomers in nature. [Pg.25]
