Diosmin

Diosmin is a disaccharide derivative that consists of diosmetin substituted by a 6-O-(alpha-L-rhamnopyranosyl)-beta-D-glucopyranosyl moiety at position 7 via a glycosidic linkage. It has a role as an antioxidant and an anti-inflammatory agent. It is a monomethoxyflavone, a rutinoside, a dihydroxyflavanone, a glycosyloxyflavone and a disaccharide derivative. It is functionally related to a diosmetin. — ChEBI
