title: [Studies on constituents from roots of Euphorbia hylonoma].
abstract: OBJECTIVE
  To study the constituents from roots of Euphorbia hylonoma.
  
  
  METHODS
  Column chromatographic techniques were used for isolation and purification of the chemical constituents and their structures were identified by spectral analysis (IR, 1H-NMR, 13C-NMR, 2D-NMR and MS).
  
  
  RESULTS
  Six compounds were isolated and elucidated as nonane (1), bis (2-ethylhexyl) phthalate (2), euphol (3), beta-sitosterol (4), acalyphol (5) and daucosterol (6) respectively.
  
  
  CONCLUSIONS
  Compounds 1, 2, 3, 5 and 6 were isolated from the plant for the first time.
