The molecule is a flavanone glycoside that consists of fustin attached to a beta-D-galactosyl moiety at position 3 via a glycosidic linkage. It is a beta-D-galactoside, a monosaccharide derivative, a member of 3'-hydroxyflavanones, a trihydroxyflavanone, a flavanone glycoside and a member of 4'-hydroxyflavanones. It derives from a fustin.
