title: [Studies on alkaloids of Asteropyrum cavaleriei (Lévl. et Vant.) Drumm. et Hutch].
abstract: OBJECTIVE
  To investigate the chemical constituents in the plant of Asteropyrum cavaleriei.
  
  
  METHODS
  The Chemical constituents were extracted with cation exchange resin 732 and separated by column chromatography, and the structures were identified by spectral analysis.
  
  
  RESULTS
  Four compounds were isolated and identified as berberine, berberrabine, palmatine and magnoflorine.
  
  
  CONCLUSIONS
  All compounds were separated from A. Cavaleriei for the first time.
