title: [Studies on the chemical constituents of Chelonopsis albiflora].
abstract: OBJECTIVE
  To study the chemical constituents of Chelonopsis albiflora.
  
  
  METHODS
  The compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS), 1H-NMR, 13C-NMR.
  
  
  RESULTS
  Seven compounds were isolated and identified as 1beta-hydroxylupenol (1), lupenol (2), beta-sitosterol (3), 13-epi-torulosal (4), 19-acetoxy-13-hydroxylabada-8 (17), 14-diene (5), (E)-p-methyl cinnamic acid (6) and vanillic acid (7) .
  
  
  CONCLUSIONS
  All compounds are isolated for the first time from this genus.
