It is an organic heterotetracyclic compound, a cyclic ketone, a lactone, a member of catechols and a polyphenol. It derives from a gallic acid. Ellagic acid, also known as ellagate, belongs to the class of organic compounds known as hydrolyzable tannins. These are tannins with a structure characterized by either of the following models. In model 1, the structure contains galloyl units (in some cases, shikimic acid units) that are linked to diverse polyol carbohydrate-, catechin-, or triterpenoid units. In model 2, contains at least two galloyl units C-C coupled to each other, and do not contain a glycosidically linked catechin unit. The antiproliferative and antioxidant properties of ellagic acid have spurred preliminary research into the potential health benefits of ellagic acid consumption. Ellagic acids therapeutic action mostly involves antioxidant and anti-proliferative/anti-cancer effects. Ellagic acid is found, on average, in the highest concentration within a few different foods, such as chestnuts, common walnuts, and japanese walnuts and in a lower concentration in whiskies, arctic blackberries, and cloudberries. Ellagic acid has also been detected, but not quantified in several different foods, such as lowbush blueberries, bilberries, guava, strawberry guava, and bog bilberries. An organic heterotetracyclic compound resulting from the formal dimerisation of gallic acid by oxidative aromatic coupling with intramolecular lactonisation of both carboxylic acid groups of the resulting biaryl.

Proanthocyanidins
Proanthocyanidins, also known as zangrado or polyhydroxyflavan-3-ol, is a member of the class of compounds known as biflavonoids and polyflavonoids. Biflavonoids and polyflavonoids are organic compounds containing at least two flavan/flavone units. These units are usually linked through CC or C-O-C bonds. Some examples include C2-O-C3, C2-O-C4, C3-C3, and C6-C8. Proanthocyanidins is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Proanthocyanidins can be found in a number of food items such as roselle, allspice, cocoa bean, and sweet bay, which makes proanthocyanidins a potential biomarker for the consumption of these food products. Proanthocyanidins were discovered in 1947 by Jacques Masquelier, who developed and patented techniques for the extraction of oligomeric proanthocyanidins from pine bark and grape seeds. Often associated with consumer products made from cranberries, grape seeds or red wine, proanthocyanidins were once proposed as factors inhibiting urinary tract infections in women, but this research has been refuted by expert scientific committees .
