Abstract
Six compounds were isolated from the 90% MeOH fraction of the vine stem of Spatholobus suberectus Dunn (Leguminosae) using silica gel, reverse phase column chromatography and RP-HPLC. Structures of compounds 1-6 were elucidated by spectroscopic parameters of IR, E1 MS, FAB MS, lD-NMR and 2D-NMR spectrum and identified as pseudobaptigenin (1), genistein (2), (2R)-7-hydroxy-6-methoxyflavanone (3), (3R,4R)-2",4"-dihydroxy-6,7-methylenedioxy-isoflavan-4-ol (4), (3R,4R)-7,2" -dihydroxy- 4"-methoxyisoflavan-4-ol (5), sativan (6), respectively. Compounds 3, 4 and 5 have been newly reported in nature.
