Grape seed extract is a kind of polyphenols extracted from grape seeds. The nature of grape seed extract depends on the extraction process used to obtain it and the growth mode of grapes. Classical methods include extraction with organic solvents (such as acetone, acetonitrile, ethyl acetate and methanol). Other methods of using hot water have been used, but in terms of quantity and efficiency, the output of the extract can not be improved to the limit of xxx. High performance liquid chromatography seems to be the most effective analytical method, and proton NMR spectrometry also has principal component analysis to ensure accurate composition.
