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. Squarrosanin B is found in Melaleuca squarrosa. Based on a literature review very few articles have been published on (10R,11S)-3,4,5,17,18,19-hexahydroxy-8,14-dioxo-10-[(1S,2S,3R)-1,2,3-trihydroxy-3-{6,7,12,13-tetrahydroxy-3,10-dioxo-2,9-dioxatetracyclo[6.6.2.0⁴,¹⁶.0¹¹,¹⁵]Hexadeca-1(15),4(16),5,7,11,13-hexaen-5-yl}propyl]-9,13-dioxatricyclo[13.4.0.0²,⁷]Nonadeca-1(19),2,4,6,15,17-hexaen-11-yl 3,4,5-trihydroxybenzoate. |
