A glycosyloxyflavone that is kaempferol attached to a alpha-L-rhamnopyranosyl(1->2)-beta-D-galactopyranosyl residue at position 3 and a alpha-L-rhamnopyranosyl residue at position 7 via glycosidic linkages. Isolated from the aerial parts of Vicia faba and Lotus edulis, it exhibits inhibitory activity against topoisomerase I.
belongs to the class of organic compounds known as flavonoid-7-o-glycosides. These are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C7-position.
