title: [Chemical constituents from flowers of Chrysanthemum indicum].
abstract: OBJECTIVE
  To investigate the chemical constituents of the flowers of Chrysanthemum indicum.
  
  
  METHODS
  The chemical constituents were isolated by various column chromatographic methods. The structures were identified by spectral data.
  
  
  RESULTS
  Twelve compounds were isolated and identified as acacetin (1), tricin (2), 2',4'-dihydroxychalcone(3), 5-hydroxy-4',7-dimethoxyflavon(4),7hydroxyflavonone (5), isorhamnetin (6),5,6,7-trihydroxy- 3',4', 5'-trimethoxyflanon (7 ), quercetin (8) , (3 beta, 5 alpha, 6 beta, 7 beta, 14 beta)-eudesmen-3,5,6,11-tetrol (9), syringaresinol (10), liriodendrin (11), and genkwanin (12).
  
  
  CONCLUSIONS
  Compounds 3-7, 10-12 were isolated from this species for the first time, and compounds 3, 5, 7, 10, 11 were obtained from genus Chrysanthemum for the first time.
