title: Isolation and characterization of novel stilbene derivatives from Riesling wine.
abstract: Besides the already known stilbenes trans-resveratrol as well as isomeric piceids seven novel stilbene derivatives have been isolated from a commercial Riesling wine. The newly identified compounds included the monostilbene 2,4,6-trihydroxyphenanthrene-2-O-glucoside, as well as two isomeric resveratrol-2-C-glucosides. In addition, four dimeric stilbenes, i.e., cis- and trans-epsilon-viniferin diglucoside as well as pallidol glucoside and pallidol diglucoside, have also been obtained for the first time from Riesling wine.
