Flavonoid-7-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position. Quercetin 7-glucoside is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Quercetin 7-glucoside can be found in a number of food items such as roman camomile, okra, dandelion, and cottonseed, which makes quercetin 7-glucoside a potential biomarker for the consumption of these food products. 7-Glucosyl quercetin 7-O-b-D-Glucopyranosyloxy-3,3',4',5-tetrahydroxyflavone Glucosyl-7-quercetin Quercetin 7-β-D-glucopyranoside Quercetin 7-β-D-glucoside Quercetin 7-glucoside Quercetin 7-monoglucoside Quercetin 7-O-β-D-glucopyranoside Quercetin 7-O-beta-D-glucoside Quercetin 7-O-glucoside Quercimeritrin Quercimeritroside C21H20O12 464.3763 464.095476104 2-(3,4-dihydroxyphenyl)-3,5-dihydroxy-7-{[(2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxy}-4H-chromen-4-one quercimeritrin 491-50-9 OC[C@H]1O[C@@H](OC2=CC(O)=C3C(=O)C(O)=C(OC3=C2)C2=CC=C(O)C(O)=C2)[C@H](O)[C@@H](O)[C@@H]1O InChI=1S/C21H20O12/c22-6-13-15(26)17(28)19(30)21(33-13)31-8-4-11(25)14-12(5-8)32-20(18(29)16(14)27)7-1-2-9(23)10(24)3-7/h1-5,13,15,17,19,21-26,28-30H,6H2/t13-,15-,17+,19-,21-/m1/s1 BBFYUPYFXSSMNV-HMGRVEAOSA-N belongs to the class of organic compounds known as flavonoid-7-o-glycosides.
