| Description | Khaephuoside B 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. (3r,4r,5s)-5-{[(2s,3r,4s,5s,6r)-4,5-dihydroxy-6-(hydroxymethyl)-2-(3,4,5-trimethoxyphenoxy)oxan-3-yl]oxy}-4-hydroxy-3-(hydroxymethyl)oxolan-3-yl 4-hydroxy-3-methoxybenzoate is found in Markhamia stipulata. (3r,4r,5s)-5-{[(2s,3r,4s,5s,6r)-4,5-dihydroxy-6-(hydroxymethyl)-2-(3,4,5-trimethoxyphenoxy)oxan-3-yl]oxy}-4-hydroxy-3-(hydroxymethyl)oxolan-3-yl 4-hydroxy-3-methoxybenzoate was first documented in 2008 (PMID: 18273876). Based on a literature review very few articles have been published on Khaephuoside B (PMID: 23702904). |
