title: [Chemical constituents from root barks of Periploca sepium].
abstract: OBJECTIVE
  To investigate the chemical constituents of the root barks of Periploca sepium.
  
  
  METHODS
  Column chromatographic techniques were used to isolate the chemical constituents. NMR and MS methods were employed for their structural elucidation.
  
  
  RESULTS
  Eight compounds were isolated and identified as isovanillin (1), vanillin (2), 4-methoxysalicylic acid (3), (24R)-9, 19-cycloart-25-ene-3beta, 24-diol (4), (24S)-9, 19-cycloart-25-ene-3beta, 24-diol (5), cycloeucalenol (6), beta-amyrin acetate (7) and alpha-amyrin (8).
  
  
  CONCLUSIONS
  Compounds 1-6 were isolated from this plant for the first time.
