IUPAC 名称
3,4,5-trihydroxy-2-{[3,4,5,22,23-pentahydroxy-8,18-dioxo-11,12,13-tris(3,4,5-trihydroxybenzoyloxy)-9,14,17-trioxatetracyclo[17.4.0.0²,⁷.0¹⁰,¹⁵]tricosa-1(19),2(7),3,5,20,22-hexaen-21-yl]oxy}benzoic acid
描述
Rugosin a 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. Rugosin a is slightly soluble (in water) and a weakly acidic compound (based on its pKa). Rugosin a can be found in cloves, which makes rugosin a a potential biomarker for the consumption of this food product.
