title: [Chemical constituents of Conyza blinii Lévl].
abstract: OBJECTIVE
  To study the chemical constituents in the air-dried part of Conyza blinii.
  
  
  METHODS
  The constituent isolation was done by solvent-extraction together with column chromatography. Several methods, such as IR, 1HNMR, 13CNMR and MS, were used to determine the structures of the isolated constituents.
  
  
  RESULTS
  Three compounds were isolated from the air-dried part of Conyza blinii and identified as friedelinol, n-triacontanol and daucosterol on the basis of physical and chemical properties and spectroscopic analysis.
  
  
  CONCLUSIONS
  These compounds have not been discovered previously in this plant.
