title: Chemical constituents of Spatholobus suberectus.
abstract: OBJECTIVE
  To investigate chemical constituents of Spatholobus suberectus Dunn.
  
  
  METHODS
  Isolation and purification were carried out by column chromatographic methods. Compounds were characterized based on their physical characteristics and spectra data.
  
  
  RESULTS
  Seventeen compounds were isolated from ethanol extract of S. suberectus. The structures were elucidated as prestegane B (1), (2R, 3R)-buteaspermanol (2), (+)-medioresinol (3), (2R, 3R)-3,7-dihydroxyflavanone (4), benzeneethanol (5), 4, 7, 2'-trihydroxy-4'-methoxyisoflavanol (6), naringenin (7), blumenol A (8), protocatechuic acid ethyl ester (9), liquiritigenin (10), 7, 4'-dihydroxy-8-methoxy-isoflavone (11), 3, 5, 7, 3', 5'-pentahydroxyflavanone (12), protocatechuic acid (13), glycyroside (14), 8-methylretusin-7-O-β-D-glucopyranoside (15), 3, 3', 4', 5, 6, 7, 8-heptahydroxyflavan (16), and dulcisflavan (17).
  
  
  CONCLUSIONS
  All compounds are firstly isolated from the title plant and compounds 1, 3 were isolated from the Spatholobus genus for the first time.
