title: [Chemical constituents from Coptis chinensis].
abstract: OBJECTIVE
  To study the chemical constituents of Coptis chinensis.
  
  
  METHODS
  The compounds were separated and purified by column chromatography and their structures were identified by spectroscopic methods.
  
  
  RESULTS
  Seven compounds were isolated from the chloroform extract of Coptis chinensis, whose structures were determined as worenine (1),8,9-dihydroxy-1,5,6, 10b-tetrahydro-2H-pyrrolo[2,1 -alpha] isoquinolin-3-one (2),(+/-) -5,5'-dimethoxy-lariciresinol (3),3,4-dihydroxy-phenylethylalcohol(4), methyl-5-O-feruloylquinate (5), ethyl-5-O- feruloylquinate (6), apocynol (7).
  
  
  CONCLUSIONS
  Compounds (3) is isolated from this genus for the first time, compounds (5), (6), (7) are isolated from this plant for the first time.
