title: [Studies on the active constituents in vine stem of Spatholobus suberectus].
abstract: OBJECTIVE
  To study the active constituents in vine stem of Spatholobus suberectus.
  
  
  METHODS
  The constituents of Spatholobus suberectus were systematically separated with various chromatographic techniques. The structures were elucidated by physico-chemical properties and spectral data.
  
  
  RESULTS
  Eight compounds were isolated from S. suberectus, and were identified as: ononin (1), pruneitin (2), gallocatechin (3), catechin (4), epicatechin (5), syringic acid (6), vanillic acid (7) and daucosterol (8).
  
  
  CONCLUSIONS
  Compound 3, 4, 6, 7 were obtained from Spatholobus genus for the first time. Compound 4 has stimulation to proliferation of hematopoietic progenitor cell.
