What are oligomeric proanthocyanidin complexes?

Oligomeric proanthocyanidins (OPCs) are compounds found in grape seed and pine bark extracts. They have been used to improve blood flow, reduce symptoms of diabetes, and to ease swelling in the joints. OPCs have also been used to improve vein function to ease swelling.

Where are oligomeric proanthocyanidins found in the body?

Oligomeric proanthocyanidins. Oligomeric proanthocyanidins (OPC) strictly refer to dimer and trimer polymerizations of catechins. OPCs are found in most plants and thus are common in the human diet. Especially the skin, seeds, and seed coats of purple or red pigmented plants contain large amounts of OPCs.

Who was the first person to discover proanthocyanidin?

Proanthocyanidin. More complex polyphenols, having the same polymeric building block, form the group of tannins . Proanthocyanidins were discovered in 1947 by Jacques Masquelier, who developed and patented techniques for the extraction of oligomeric proanthocyanidins from pine bark and grape seeds.

How are the monomers of proanthocyanidins characterized?
