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.
