ChEBI: Neoastilbin is a flavanone glycoside that is (-)-taxifolin substituted by a alpha-L-rhamnosyl moiety at position 3 via a glycosidic linkage. It is an alpha-L-rhamnoside, a member of 3'-hydroxyflavanones, a tetrahydroxyflavanone, a monosaccharide derivative, a flavanone glycoside and a member of 4'-hydroxyflavanones. It is functionally related to a (-)-taxifolin. It is an enantiomer of an astilbin. |
