title: [Chemical constituents from root of Psammosilene tunicoides].
abstract: OBJECTIVE
  To investigate the chemical constituents from the root of Psammosilene tunicoides.
  
  
  METHODS
  Column chromatographic methods were used to isolate the chemical constituents of this plant. ESI-MS, EI-MS and NMR methods were employed for their structural elucidation.
  
  
  RESULTS
  Seven compounds were isolated and identified as goyaprosaponin (1), Soya-cerebroside (2), tectoridin (3), alpha-spinasterol (4), tetracosanoic acid (5), beta-sitosterol (6), daucosterol (7) respectively.
  
  
  CONCLUSIONS
  Compounds 2-7 were obtained from genus Psammosilene for the first time.
