Encyclopedia: Oligomeric proanthocyanidin 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. Oligomeric proanthocyanidin complexes are primarily known for their free radical scavenging and antioxidant activity. In vivo studies have shown grape seed proanthocyanidin extract is a better free radical scavenger and inhibitor of oxidative tissue damage than vitamin C, vitamin E succinate, vitamin C and vitamin E succinate combined, and beta carotene. www.nationmaster.com /encyclopedia/Oligomeric-proanthocyanidin   (1324 words)

Antioxidant Grape Seeds Extract, Oligomeric Proanthocyanidins, OPC Oligomeric proanthocyanidin or proanthocyanidins, often used interchangeable, are clusters of phenolic compounds built from single monomer units called catechin and epi-catechin. 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. The presence of anthocyanidins (red color) as a result of conversion from proanthocyanidins (colorless) in an acid environment. www.nutrisana.com /html/grape.seeds.extract.html   (2420 words)
