title: [Study on chemical components of Tripterospermum chinense].
abstract: OBJECTIVE
  To investigate the chemical components of the whole herb of Tripterospermum chinense.
  
  
  METHODS
  Various column chromatography methods were used in the isolation and purification. Physio-chemical constant determination and spectral analysis were adopted to determine the chemical structures.
  
  
  RESULTS
  Ten compounds were isolated and identified as 1, 7-dihydroxy-3,8-dimethoxyxanthone(1),1,3-dihydroxy-7,8-dimethoxyxanthone (2) 1,3,6,7-tetrahydroxyxanthone (3),1,8-dihydroxyxanthone(4),2'-deoxythymidine(5), 4-hydroxyphthalide(6),2,4-dihydroxy benzyl alcohol (7),2,5-dihydroxyphenetole (8), saponarin (9) and 4'-methoxysaponarin(10).
  
  
  CONCLUSIONS
  Compounds 2 - 8 and 10 are isolated from this plant for the first time.
