What is Ombuoside?

Plain description, key identifiers and synonyms

Ombuoside is a glycosyloxyflavone that is ombuin attached to a rutinoside residue at position 3 via a glycosidic linkage. It has a role as an antibacterial agent, a radical scavenger, a neuroprotective agent and a plant metabolite. It is a dimethoxyflavone, a rutinoside, a dihydroxyflavone, a glycosyloxyflavone and a disaccharide derivative. It is functionally related to a rutinose and an ombuin.
