Description | Gomisin D 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. 12,25-dihydroxy-18,19,20-trimethoxy-11,12,24,25-tetramethyl-4,6,9,14-tetraoxapentacyclo[13.7.3.0³,⁷.0⁸,²².0¹⁶,²¹]pentacosa-1(22),2,7,16(21),17,19-hexaen-13-one is found in Kadsura coccinea and Schisandra chinensis. Gomisin D is an extremely weak basic (essentially neutral) compound (based on its pKa). |
