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.Fuctions:1.Anti-oxidant,anti-aging2.Cardiovascular diseases3.Anti-cancerPackage: Packed in Paper-Drum and two pieces of plastic bag inside.  N.W.: 25kg/drumStorage condition: Sealed in well-closed container and avoid moisture and light.Shelf life: Two years according to storage condition.
