IUPAC 名称
6,7,8,11,12,13,21,22,23-nonahydroxy-2,17,20-trioxatetracyclo[17.3.1.0^{4,9}.0^{10,15}]tricosa-4,6,8,10,12,14-hexaene-3,16-dione
描述
3,6-hexahydroxydiphenoylglucose 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. 3,6-hexahydroxydiphenoylglucose is soluble (in water) and a very weakly acidic compound (based on its pKa). 3,6-hexahydroxydiphenoylglucose can be found in pomegranate, which makes 3,6-hexahydroxydiphenoylglucose a potential biomarker for the consumption of this food product.
