Resveratrol: a molecule whose time has come? And gone?
TL;DR: Up to the present, conclusive evidence for its absorption by human subjectsin biologically significant amounts is lacking, and it is questionable that its powerful and beneficial in vitro activities are reproduced as a consequence of sustained moderate red wine consumption.

Resveratrol: Isomeric Molar Absorptivities and Stability
TL;DR: In this paper, the molar absorptivity and chemical stability of cis- and trans-resveratrol have been investigated and the results show that trans-Resveratols is stable for months, except in high pH buffers, when protected from light.

Direct bioautography on thin-layer chromatograms as a method for detecting fungitoxic substances
A.L. Homans,A. Fuchs +1 more
TL;DR: Chromatography permits not only the detection of fungitoxic substances per se, but also makes the study of the conversion reactions and of decomposition of such compounds possible.

Formation and activity of phaseollin in the interaction between bean hypocotyls (Phaseolus vulgaris) and physiological races of Colletotrichum lindemuthianum
J.A. Bailey,B.J. Deverall +1 more
TL;DR: Quantitative measurements, using thin layer chromatography plus ultraviolet spectophotometry and gas-liquid chromatography, have shown that phaseollin accumulation was limited to infected tissue which was visibly brown, and experiments indicated thatphaseollin was metabolized by hyphae in liquid culture.
