摘要
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-alpha-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.
