title: [Studies on the chemical constituents from Aquilegia ecalcarata Maxim].
abstract: OBJECTIVE
  To study the chemical constituents from Aquilegia ecalcarata.
  
  
  METHODS
  Compounds were isolated with silica gel and polyamide chromatography and their structures were determined by spectral analysis and chemical evidence.
  
  
  RESULTS
  Five compounds were obtained and identified as beta-sitosterol, isoorientin-7-O-glucoside, isovitexin-4'-O-glucoside, isovitexin-2'-O-rhamnoside, luteolin-7-O-glucoside.
  
  
  CONCLUSIONS
  All the compounds were isolated from this plant for the first time.
