Grape seed extract is an industrial derivative of whole grape seeds. The extract (GSPE) contains proanthocyanidins. [1] Grape seed extract quality is measured by the content of procyanidins which are formed from proanthocyanidins. [2] Generally, grape seed extract quality contains 95% procyanidins, but potency varies among products. [3]
Seed oils are characterized by the industrial process used to extract the oil from the seed and a high content of polyunsaturated fatty acids (PUFAs). [10] Critics' "hateful eight" oils consist of canola, corn, cottonseed, soy, sunflower, safflower, grapeseed, and rice bran oils, [ 8 ] which are creations of industrialization in the early ...
Grape therapy or grape diet, also known as ampelotherapy, is a diet that involves heavy consumption of grapes, including seeds, and parts of the vine, including leaves, that is a form of alternative medicine. The concept was developed in 19th-century Germany in spas such as Bad Duerkheim and Merano. [1]
The Porter Assay is a chemical test to help determine the potency of procyanidin containing compounds, such as grape seed extract. It is an acid hydrolysis, which splits larger chain units (dimers and trimers) into single unit monomers and oxidizes them. This leads to a colour change, which can be measured using a spectrophotometer. The greater ...

They are dense in grape seeds and skin, and therefore in red wine and grape seed extract, cocoa, nuts and all Prunus fruits (most concentrated in the skin), and in the bark of Cinnamomum [4] and Pinus pinaster (pine bark; formerly known as Pinus maritima), along with many other pine species.
[1] [2] [12] These chemicals were not present in grapefruit seed extracts prepared in the laboratory, and GSE preparations without the contaminants were found to possess no detectable antimicrobial effect. [1] Although citrus seed extract is sold in health food markets, [12] there is no good evidence for any antimicrobial activity. [1]
