title: [Study on chemical constituents of Cardiospermum halicacabum].
abstract: OBJECTIVE
  To study the chemical constituents of Cardiospermum halicacabum.
  
  
  METHODS
  The constituents were isolated and purified by silica gel and polyamide, their chemical structures were identified by physicochemcial properties and spectral methods.
  
  
  RESULTS
  Eight compounds were separated and identified as: pentadecanoie acid (1), apigenin (2), protocatechuic acid (3), protocatechualdehyde (4), hentriacontanol (5), calycosin (6), rutin (7), quercetin (8).
  
  
  CONCLUSIONS
  All compounds are isolated from this plant for the first time.
