title: [Chemical constituents of Dipsacus asper].
abstract: OBJECTIVE
  To study the chemical constituents of Dipsacus asper.
  
  
  METHODS
  Column chromatography on Silica gel and RP-C18 were applied for isolation and purification of the constituents. Their structures were identified by spectral and chemical methods.
  
  
  RESULTS
  From the crude MeOH fraction of Dipsacus asper, 12 compounds were isolated and identified as Sucrose (1), beta-sitosterol (2), Oleanic acid (3), Triplostoside A (4), Loganin (5), Loganin acid (6), Sweroside (7), Epi-vogeloside ( 8), Vogeloside (9), Akebiasaponin D(10), Cauloside A(11),7-Deoxyloganic acid (12).
  
  
  CONCLUSIONS
  Compounds 8, 9, 12 are isolated from this plant for the first time.
