Common Name | Vescalagin |

Description | Vescalagin, also known as vescalene or castalagin, 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. Castalagin thus forms from a pentagalloyl-glucose structure. After conversion of casuarictin to pedunculagin, the pyranose ring of the glucose opens and the family of compounds including casuariin, casuarinin, castalagin, and castlin, vescalagin and vescalin forms. Vescalagin is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, vescalagin has been detected, but not quantified in, a few different foods, such as european chestnuts, nuts, and pomegranates. This could make vescalagin a potential biomarker for the consumption of these foods. Vescalagin is one of the most abundant ellagitannins extracted from oak wood using white wine. Castalagin is an ellagitannin, a type of hydrolyzable tannin, found in oak and chestnut wood and in the stem barks of Anogeissus leiocarpus and Terminalia avicennoides. During aging of alcohols in oak barrels, vescalagin can be extracted from the wood and can subsequently be transformed into new derivatives by chemical reactions. In some plants including oak and chestnut, the ellagitannins are formed from 1,2,3,4,6-pentagalloyl-glucose and further elaborated via oxidative dehydrogenation (tellimagrandin II and casuarictin formations). Castalagin and vescalagin (1,2,3,5-nonahydroxytriphenoyl-4,6-hexahydroxydiphenoyl-glucoses) can be further polymerized in their corresponding dimers roburin A and roburin D, and 33-carboxy-33-deoxyvescalagin. Castalagin is the (33beta)-isomer of vescalagin. Grandinin is a castalagin glycoside by binding of the pentose lyxose. The flavono-ellagitannin known as acutissimin A is created when the oak tannin vescalagin interacts with a flavonoid in wine. |
