Abstract
A new resveratrol tetramer, shoreaketone, was isolated from the stem bark of Shorea uliginosa (Dipterocarpaceae). The structure has a novel framework of heptacyclic ring system including an α,β-unsaturated carbonyl group. In NMR spectra shoreaketone is observed as two different conformers due to rotational isomerism.
