Astilbin from Engelhardtia roxburghiana

Astilbin is a flavanone glycoside that is (+)-taxifolin substituted by a alpha-L-rhamnosyl moiety at position 3 via a glycosidic linkage. It has a role as a radical scavenger, an anti-inflammatory agent and a plant metabolite. It is a member of 4'-hydroxyflavanones, an alpha-L-rhamnoside, a tetrahydroxyflavanone, a member of 3'-hydroxyflavanones, a monosaccharide derivative and a flavanone glycoside. It is functionally related to a (+)-taxifolin. It is an enantiomer of a neoastilbin.
