描述
Piceatannol, also known as (Z)-3,5,3',4'-tetrahydroxystilbene, is a member of the class of compounds known as stilbenes. Stilbenes are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids. Piceatannol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Piceatannol can be synthesized from cis-stilbene. Piceatannol can also be synthesized into cis-astringin. Piceatannol can be found in common grape and grape wine, which makes piceatannol a potential biomarker for the consumption of these food products. Piceatannol is a stilbenoid, a type of phenolic compound .
