title: [Studies on the alkaloids from roots of Corydalis impatiens].
abstract: OBJECTIVE
  To study the alkaloids from Corydalis impatiens.
  
  
  METHODS
  The alkaloids were isolated and purified by chromatography and their structures were identified by spectral data and others methods.
  
  
  RESULTS
  Seven alkaloids were isolated and identified as bicuculline(1), ochotensine(2), ochotensimine(3), ochrobirine(4), tetrahydrothalifendine(5), norochotensimine(6), N-methylactinodaphnine(7).
  
  
  CONCLUSIONS
  All these compounds are isolated from this plant for the first time.
