描述
Pedunculagin is a member of the class of compounds known as hydrolyzable tannins. Hydrolyzable tannins 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) 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. Pedunculagin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Pedunculagin can be found in a number of food items such as cloves, rubus (blackberry, raspberry), red raspberry, and guava, which makes pedunculagin a potential biomarker for the consumption of these food products. Pedunculagin is an ellagitannin. It is formed from casuarictin via the loss of a gallate group .
