Superiority
Grape seed extract is an industrial derivative of whole grape seeds.
The extract contains proanthocyanidins. Grape seed extract quality is measured by the content of procyanidins which are formed from proanthocyanidins.
Generally, grape seed extract quality contains 95% procyanidins, but potency varies among products.
The properties of grape seed extract depends on the extraction process used to obtain it and how the grapes were grown.
The classic method incorporates extraction with organic solvents such as acetone, acetonitrile, ethyl acetate, and methanol.
