What is Grape Seed Extract?  Grape seed extract, which is made from the seeds of wine grapes, is promoted as a dietary supplement for various conditions. Grape seed extract contains proanthocyanidins, which have been studied for a variety of health conditions.

Production of Grape Seed Extract  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. Other methods using hot water have been used, but are not as effective in maximizing in extract production in both quantity and efficiency. High performance liquid chromatography seems to be the most effective analysis along with proton NMR spectroscopy with principal component analysis to ensure accurate composition.
