  Oligomeric proanthocyanidin - Wikipedia, the free encyclopedia
Oligomeric proanthocyanidins or OPCs are a class of flavonoid complexes found in grape seeds and skin, that act as antioxidants (free radical scavengers) in the human body.
Proanthocyanidins-also called "OPCs" for oligomeric proanthocyanidins and "PCOs" for procyanicolic oligomers are a class of nutrients belonging to the bioflavonoid family.
Proanthocyanidins have antioxidant activity and they play a role in the stabilization of collagen and maintenance of elastin—two critical proteins in connective tissue that support organs, joints, blood vessels, and muscle.

 Oligomeric Proanthocyanidin   (Site not responding. Last check: 2007-11-05)
Proanthocyanidins belong to the category known as condensed tannins, one of the two main categories of plant tannins (Table 2).
Proanthocyanidins are high-molecular-weight polymers comprised of the monomeric unit flavan-3-ol ((+)catechin and (-) epicatechin).
Oligomeric proanthocyanidin complexes are primarily known for their free radical scavenging and antioxidant activity.

Proanthocyanidin is a specific class of bioflavanoids found in a wide number of plants, including purple, red and white grapes, as well as pine bark, lemon tree bark, hazel nut tree leaves, blue berries, cherries, cranberries and others.
Proanthocyanidin has been shown to be the active principle that makes both pine bark and Grape Seed Extract so effective as an antioxidant and collagen and elastin protector.

 Antioxidant Grape Seeds Extract, Oligomeric Proanthocyanidins, OPC
Proanthocyanidins, also known as OPCs and leukocyanidins — to cite only their most common names — are a group of bioflavonoids which, until 1936, were known as Vitamin P. The discovery of proanthocyanidins is attributed to a Frenchman, Professor Jacques Masquelier, who devoted a half century to researching them.
Oligomeric proanthocyanidin or proanthocyanidins, often used interchangeable, are clusters of phenolic compounds built from single monomer units called catechin and epi-catechin.
Although the definition of oligomeric varies somewhat, dimers (two units), trimers (three units) and sometimes up to heptamers (seven units) are generally referred to as oligomeric while larger complexes are referred to as polymeric and/or tannins.

Although the majority of the studies conducted on OPCs have been done in cell culture (test tube) and animals, their ability to reduce free radical damage and oxidative stress suggest that they may be particularly effective in reducing the risk of cancer, cardiovascular disease and a number of the chronic diseases associated with aging.
In some test models, proanthocyanidins are 50 times more potent antioxidants than the two most famous antioxidants, vitamins C and E. Sophisticated tests have shown proanthocyanidins to be powerful quenchers of the hydroxyl radical, the most damaging of all common free radicals, as well as lipid peroxides (rancid fats).
Proanthocyanidins inhibit enzymes such as hyaluronidase, collagenase and elastase that can break down the collagen structure of blood vessel walls.1 This fact is especially important for brain health, due to the blood-brain barrier.
