Proanthocyanidin - Wikipedia
Proanthocyanidins are a class of polyphenols found in many plants, such as cranberry, blueberry, and grape seeds. Chemically, they are oligomeric flavonoids. Many are oligomers of catechin and epicatechin and their gallic acid esters. More complex polyphenols, having the same polymeric building block, form the group of condensed tannins.
Proanthocyanidins: A comprehensive review - ScienceDirect
2019年8月1日 · Proanthocyanidins are oligo- or polymers of monomeric flavan-3-ols produced as an end product of flavonoid biosynthetic pathway. Agricultural wastes and food processing wastes contain immense amount of proanthocyanidins, exploitation of which can be a sustainable source of dietary supplements and functional ingredients.

Proanthocyanidins are chemical compounds. They give the fruit or flowers of many plants their red, blue, or purple colors. They were first studied for their importance as plant pigments. These compounds have anti-inflammatory properties and may help prevent cancer. Proanthocyanidins are in a group of compounds called polyphenols.
