| Description | Quercetagitrin 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. 2-(3,4-dihydroxyphenyl)-3,5,6-trihydroxy-7-{[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}chromen-4-one is found in Achillea micrantha, Actinocephalus polyanthus, Tagetes erecta, Clibadium surinamense, Helichrysum stoechas, Neurolaena lobata and Tagetes lucida. Quercetagitrin is an extremely weak basic (essentially neutral) compound (based on its pKa). |
