除了已知的二苯乙烯反式白藜芦醇以及异构白藜芦醇外，还从商业雷司令葡萄酒中分离出了七种新型二苯乙烯衍生物。新鉴定的化合物包括单芪2,4,6-三羟基菲-2-O-葡萄糖苷，以及两种异构体白藜芦醇-2-C-葡萄糖苷。此外，还首次从雷司令葡萄酒中分离得到顺式和反式ε-葡萄苷二葡萄糖苷、苍白醇葡萄糖苷和苍白醇二葡萄糖苷四种二聚二苯乙烯类化合物。
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.
