Two pterocarpans ［(6aR,11aR）-maackiain, (6aR,11aR）-medicarpin］, one flavanone ［(2S）-7-hydroxy-G-methoxy-flavanone］, one isoflavan (sativan） and two isoflavones (pseudobaptigenin, genistein） were isolated from the Spatholobus suberectus (Leguminosae）. Their chemical structures were determined by comparison of their spectroscopic parameters of CD, ElMS, 1D-NMR and 2D-NMR with those reported in the literatures. All of these compounds are reported for the first time from this plant through the present study.
