title: [Pyrrolizidine alkaloids of Senecio cannabifolius var. integrilifolius].
abstract: OBJECTIVE
  To study the pyrrolizidine alkaloids of Senecio cannabifolius var. integrilifolius.
  
  
  METHODS
  Various chromatographic methods were used for the isolation and purification of chemical constitutents of the plant and their structures were elucidated on the basis of spectral analysis.
  
  
  RESULTS
  Four compounds were determinated as jacobine(1), jacoline(2), jaconine(3), senecicannabine(4).
  
  
  CONCLUSIONS
  All compounds were isolated from this plant for the first time.
