What is Grape seed Extract?
Grape seed extracts are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid and phenolic procyanidins (also known as OPC or oligomeric procyanidins). Grape seed extract can be applied topically or taken internally, and is the best known source of antioxidants available.
Chemical constituents of Grape seed extract
The main ingredients are procyanidins and OPC
Grape seed extract is a heterogeneous mixture of gallic acid, monomers, dimers, trimers, tetramers, polymers and other oligomers. The basic building blocks are molecules of catechin, epicatechin, epicatechin gallate, gallic acid esters, glycosides and peptides. Due to the high degree of heterogeneity, several analytical techniques are required to characterize grape seed extract.
