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. Strictinin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Strictinin can be found in cloves, guava, pomegranate, and tea, which makes strictinin a potential biomarker for the consumption of these food products. Strictinin is a bioactive chemical of the ellagitannin family of hydrolyzable tannins.This compound shows activity against influenza virus . 1-O-Galloyl-4,6-(S)-hexahydroxydiphenoyl-b-D-glucopyranose Shepherdia argentea leaf isolate Strictinin C27H22O18 634.4528 634.0806139 3,4,5,11,12,21,22,23-octahydroxy-8,18-dioxo-9,14,17-trioxatetracyclo[17.4.0.0²,⁷.0¹⁰,¹⁵]tricosa-1(19),2,4,6,20,22-hexaen-13-yl 3,4,5-trihydroxybenzoate 3,4,5,11,12,21,22,23-octahydroxy-8,18-dioxo-9,14,17-trioxatetracyclo[17.4.0.0²,⁷.0¹⁰,¹⁵]tricosa-1(19),2,4,6,20,22-hexaen-13-yl 3,4,5-trihydroxybenzoate 517-46-4 OC1C(O)C2OC(=O)C3=CC(O)=C(O)C(O)=C3C3=C(C=C(O)C(O)=C3O)C(=O)OCC2OC1OC(=O)C1=CC(O)=C(O)C(O)=C1 InChI=1S/C27H22O18/c28-9-1-6(2-10(29)16(9)32)24(39)45-27-22(38)21(37)23-13(43-27)5-42-25(40)7-3-11(30)17(33)19(35)14(7)15-8(26(41)44-23)4-12(31)18(34)20(15)36/h1-4,13,21-23,27-38H,5H2 FYIJLTSMNXUNLT-UHFFFAOYSA-N belongs to the class of organic compounds known as hydrolyzable tannins.
