Common Name | Tellimagrandin II |
---|
Description | Tellimagrandin II, also known as cornustannin 2 or eugeniin, 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. It is further oxidized to casuarictin, a molecule formed via oxidative dehydrogenation of 2 other galloyl groups in Casuarina and Stachyurus species. It is formed by oxidation of pentagalloyl glucose in Tellima grandiflora by the enzyme pentagalloylglucose: O(2) oxidoreductase, a laccase-type phenol oxidase. Tellimagrandin II is an extremely weak basic (essentially neutral) compound (based on its pKa). The compound shows anti-herpesvirus properties. Outside of the human body, tellimagrandin II is found, on average, in the highest concentration in cloves. tellimagrandin II has also been detected, but not quantified in, several different foods, such as lambsquarters, millets, japanese persimmons, green bell peppers, and black cabbages. This could make tellimagrandin II a potential biomarker for the consumption of these foods. Tellimagrandin II is the first of the ellagitannins formed from 1,2,3,4,6-pentagalloyl-glucose. Tellimagrandin II is an isomer of punicafolin or nupharin A, but the hexahydroxydiphenoyl group is not attached to the same hydroxyl groups in the glucose molecule. It is laccase-catalyzed dimerized to cornusiin E in Tellima grandiflora. It can be found in Geum japonicum and Syzygium aromaticum (clove). |
