Chemical Information
FooDB NamePunicalin
DescriptionPunicalin 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. Punicalin is an extremely weak basic (essentially neutral) compound (based on its pKa). Punicalin is found, on average, in the highest concentration within pomegranates. Punicalin has also been detected, but not quantified in, fruits. This could make punicalin a potential biomarker for the consumption of these foods.
