Definition

Astilbin, also known as (2s-cis)-isomer of astilbin or isoastilbin, is a member of the class of compounds known as flavonoid-3-o-glycosides. Flavonoid-3-o-glycosides are phenolic compounds containing a flavonoid moiety which is O-glycosidically linked to carbohydrate moiety at the C3-position. Astilbin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Astilbin can be found in alcoholic beverages, common grape, fruits, and grape wine, which makes astilbin a potential biomarker for the consumption of these food products. Astilbin exists in all eukaryotes, ranging from yeast to humans. Astilbin is a flavanonol, a type of flavonoid. Astilbin is the (2R-trans)-isomer; neoisoastilbin is the (2S-cis)-isomer and isoastilbin is the (2R-cis)-isomer .
