title: Two new chalcones from Clerodendrum phlomidis.
abstract: Two new chalcones, 3,2',3'-trihydroxy-4'-methoxychalcone (1) and 3,2'-dihydroxy-4',6'-dimethoxychalcone (2), were isolated from the seeds of Clerodendrum phlomidis together with three known flavonoids, 5-hydroxy-7-methoxyflavanone (3), 5-hydroxy-7-methoxyflavone (4), and kaempferol-3-O-α-l-rhamnopyranoside (5). The structures of the new compounds 1 and 2 have been established mainly on the basis of 1D and 2D NMR studies.
