What is Astragalin?

Plain description, key identifiers and synonyms

Kaempferol 3-O-beta-D-glucoside is a kaempferol O-glucoside in which a glucosyl residue is attached at position 3 of kaempferol via a beta-glycosidic linkage. It has a role as a trypanocidal drug and a plant metabolite. It is a beta-D-glucoside, a trihydroxyflavone, a monosaccharide derivative and a kaempferol O-glucoside. It is a conjugate acid of a kaempferol 3-O-beta-D-glucoside(1-).
