title: [Studies on chemical constitutents in seeds of Allium tuberosum Rottl].
abstract: OBJECTIVE
  To study the chemical constituents in the seed of Allium tuberosum.
  
  
  METHODS
  Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures.
  
  
  RESULTS
  Five compounds were isolated from the alcohol extracts of the seeds and identified as nicotianoside C, (22S)-cholest-5-ene-1 beta, 3 beta, 16 beta, 22-tetrol-1-O-alpha-L-rhamnopyranosyl-16-O-beta-D-glucopyranoside, daucosterol, adenosine and thymidine.
  
  
  CONCLUSIONS
  All the compounds were isolated from the seed of this plant for the first time.
