title: [Alkaloid constituents of Corydalis adunca].
abstract: OBJECTIVE
  To study the alkaloid component of Corydalis adunca Maxim.
  
  
  METHODS
  The constituents were isolated by chromatographic methods, their structures were elucidated by spectroscopic evidences.
  
  
  RESULTS
  Three compounds were purified and their structures were identified, they were identified as dorydaline (I), dehydrocorydaline (II), dihydrosanguinarine (III).
  
  
  CONCLUSIONS
  Compounds I , II are isolated from this plant for the first time.
