title: [Chemical constituents from flowers of Carthamus tinctorius].
abstract: OBJECTIVE
  To study the chemical constituents from the flowers of Carthamus tinctorius.
  
  
  METHODS
  Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectral methods.
  
  
  RESULTS
  Ten compounds were identified as 7,8-dimethylpyrazino [2,3-g] quinazolin-2, 4-(1H, 3H) -dione (1), adenosine (2), adenine (3), uridine (4), thymine (5), uracil (6), roseoside (7), 4'-O-dihydrophaseic acid-beta-D-glucopyranoside methylester (8), 4-O-beta-D-glucopyranosyloxy-benzoic acid (9) and p-hydroxybenzoic acid (10).
  
  
  CONCLUSIONS
  Compounds 1 and 8 were isolated from natural plants for the first time, and compounds 7, 9 and 10 were isolated from this plant for the first time.
