introductions:
proanthocyanidin (pa or pac), also known as procyanidin, oligomeric proanthocyanidin (opc), leukocyanidin, leucoanthocyanin and condensed tannins, is a class of flavanols. Proanthocyanidins are essentially polymer chains of flavonoids such as catechins. One was discovered in 1936 by professor jacques masquelier and called vitamin p, although this name did not gain official category status and has since fallen out of usage. It was masquelier who first developed techniques for the extraction of proanthocyanidins from certain plant species.
Polyphenols are a group of chemical substances found in plants, characterized by the presence of more than one phenol unit or building block per molecule. Polyphenols are generally divided into hydrolyzable tannins (gallic acid esters of glucose and other sugars) and phenylpropanoids, such as lignins, flavonoids, and condensed tannins.
Why choose orac grape seed p.e.?
antioxidants are compounds that have the capacity to neutralize reactive oxygen species. Oxygen free radicals generated by oxidative and other biochemical pathways are the main cause for a number of degenerative diseases. Antioxidants act as radical scavengers, and convert the radicals to less reactive species. The imblanace due to the presence of excess free radicals and lower antioxidants causes oxidative stress and many chronic health problems such as cancer, atherosclerosis, myocardial infraction, senile cataracts, and rheumatoid arthritis.research indicates that gse proanthocyanidinspolyphenl has strong antioxidants. Its antioxidative is 50times than vitamin e, and 20times than vitamin c.
