Abstract
Two major ellagitannins from Quercus robur, vescalagin and castalagin, were studied by H-1 NMR and LSI-mass spectrometry, and molecular mech anics. A plausible 3D-structure is proposed for each of the two diaste reoisomers. These structures were the most stable ones found after a c onformational analysis study and their calculated NMR spectra are in g ood accordance with measured ones.
