TL;DR: A significant relationship between antioxidant capacity and total phenolic content was found, indicating that phenolic compounds are the major contributors to the antioxidant properties of these plants.

TL;DR: It is demonstrated that trans-resveratrol is bioavailable following oral administration and remains mostly in intact form, and a wide range of target organs for cancer chemoprevention by wine polyphenols in humans is suggested.

TL;DR: It is described a method for the direct determination of stilbenes in several red wines using high-performance liquid chromatography with UV detection and a compound isolated for the first time in wine, trans-delta-viniferin, achieved by NMR after extraction and fractionation of red wine phenolics.

TL;DR: It is found that the phosphorylation of hexose by hexokinase, but not its transport, has to be taken into account for the sucrose signal transduction leading to anthocyanin accumulation.

TL;DR: In this article, the authors describe the simultaneous determination of six resveratrol derivatives in wines by liquid chromatography (LC) with fluorescence detection, and the levels of pallidol, the symmetrical dimer of reserveratrol, are reported for the first time.
