What is Robinin?
Chemical properties
Robinin is a flavone belonging to the flavonol glycosides occurring in Robinia species, e. g., Robinia pseudoacacia (Fabaceae) and in Pueraria and Vigna species (Fabaceae). Robinin has been reported to have antibacterial activity.
Definition
ChEBI: Robinin is a glycosyloxyflavone that is kaempherol substituted by a 6-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-galactopyranosyl residue at position 3 and a 6-deoxy-alpha-L-mannopyranosyl residue at position 7 via a glycosidic linkage. It has a role as a plant metabolite. It is a glycosyloxyflavone and a dihydroxyflavone. It is functionally related to a kaempferol.
