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. 4,4'-dimethoxystilbene is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 4,4'-dimethoxystilbene can be found in anise, which makes 4,4'-dimethoxystilbene a potential biomarker for the consumption of this food product.
