title: Two new flavonoids from the seeds of Derris scandens.
abstract: Two new flavonoids, (2S)-3',4',5'-trimethoxyflavanone (1) and 2'-hydroxy-2,4-dimethoxy-4'-O-[(E)-3,7-dimethyl-2,6-octadienyl]chalcone (2), together with a known pterocarpene, flemichapparin B (3), and a known rotenoid, dehydrodeguelin (4), were isolated from the seeds of Derris scandens. Their structures were determined by means of extensive 1D and 2D NMR spectral studies.
