title: Two new chalcones from the flowers of Clerodendrum inerme.
abstract: Two new chalcones, 3-hydroxy-3',4'-dimethoxychalcone (1) and 3,2'-dihydroxy-3',4'-dimethoxychalcone (2), were isolated from the flowers of Clerodendrum inerme (L.) Gaertn together with two known flavones, 7-O-methylwogonin (3) and eucalyptin (4). The structures of the new compounds 1 and 2 have been established by extensive 2D-NMR and ESI-TOFMS studies.
