title: [Studies on the chemical constituents from Lobelia chinensis].
abstract: OBJECTIVE
  To study the chemical constituents of the full plant of Lobelia chinensis.
  
  
  METHODS
  The compounds were isolated and purified using several column chromatographic methods. Their structures were elucidated based on their physicochemical properties and spectral data.
  
  
  RESULTS
  Twelve compounds were isolated from L. chinensis. Their structures were elucidated as 6,7-dimethoxycoumarin (1), fraxinol (2), 5-hydroxy-7-methoxycoumarin (3), tomentin (4), 3'-hydroxygenkwanin (5), apigenin (6), quercetin (7), luteolin (8), linarin (9), luteolin 3',4'-dimethylether-7-O-beta-D-glucoside (10), isoferulic acid (11), and ethyl ros-marinate (12), respectively.
  
  
  CONCLUSIONS
  Compounds 1 -5 and 10 -12 are isolated from this plant for the first time.
