Chemical Information
FooDB NamePunicalagin
DescriptionConstituent of Punica granatum (pomegranate) Punicalagin is the major tannin component of Terminalia catappa and have been characterized to possess antioxidative and anti-genotoxic activities. ; T. catappa has been a popular folk medicine for preventing hepatoma and treating hepatitis in Taiwan; the leaves contain many hydrolyzable tannins. Although the leaves of T. catappa have been claimed to be effective in preventing hepatoma, the mechanism of its chemopreventive effect remains to be elucidated, and their effects on reactive oxygen species (ROS) mediated carcinogenesis are still unclear. (PMID: 16242868). Punicalagin is found in fruits and pomegranate.

Classification
DescriptionThis compound 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 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.
