Luteolin-7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide] is the glycosyloxyflavone resulting from the condensation of the hydroxy group at position 7 of luteolin with the 1 position of 2-O-beta-D-glucopyranuronosyl-beta-D-glucopyranosiduronic acid. It is a trihydroxyflavone, a glycosyloxyflavone, a dicarboxylic acid, a disaccharide derivative and a luteolin O-glucuronoside. It is a conjugate acid of a luteolin 7-O-[(beta-D-glucosiduronate)-(1->2)-(beta-D-glucosiduronate)]. luteolin-7-O-[beta-D-glucuronosyl-(1->2)-beta-D-glucuronide] is a natural product found in Elodea canadensis, Medicago truncatula, and other organisms with data available. This compound belongs to the family of Flavonoid O-Glycosides. These are compounds containing a carbohydrate moiety which is o-glycosidically linked to one of the flavonoid backbones (2-phenylchromen-4-one, 3-phenylchromen-4-one or 4-phenylcoumarin). The glycosyloxyflavone resulting from the condensation of the hydroxy group at position 7 of luteolin with the 1 position of 2-O-beta-D-glucopyranuronosyl-beta-D-glucopyranosiduronic acid. Luteolin 7-diglucuronide is the major flavonoid isolated from Aloysia triphylla and Verbena officinalis[1].
