Abstract
Two prenylated dihydrostilbenes have been isolated from the methanol extract of the flower of Croton laevifolius. The structures of these compounds were assigned as 3,5,3′,4′-tetrahydroxy-2,6,2′-tris(3-methylbut-2-enyl)dihydrostilbene (laevifolin A) and 3,5,3′,4′-tetrahydroxy-2,6,5′-tris(3-methylbut-2-enyl)dihydrostilbene (laevifolin B) based on spectroscopic evidence, including UV, IR, 1D and 2D NMR, and mass spectra. The chemotaxonomic significance of the presence of these dihydrostilbene derivatives is briefly discussed.
