Ellagic acid glucoside
IUPAC 名称
7,13,14-trihydroxy-6-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-2,9-dioxatetracyclo[6.6.2.0⁴,¹⁶.0¹¹,¹⁵]hexadeca-1(15),4(16),5,7,11,13-hexaene-3,10-dione
描述
Ellagic acid glucoside 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. Ellagic acid glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Ellagic acid glucoside can be found in pomegranate and strawberry, which makes ellagic acid glucoside a potential biomarker for the consumption of these food products.
