title: [Lipid compounds from Echinacea purpurea].
abstract: OBJECTIVE
  To study the lipid constituents from Echinacea purpurea.
  
  
  METHODS
  The compounds were isolated by chromatography method and the structures were identified on the basis of spectral analyses.
  
  
  RESULTS
  Five compounds were isolated and identified as, 1 beta, 6 alpha-dihydroxy-4(14)-eudesmene(1), (2E, 4E, 8Z, 10E)-N-isobutyl-2,4,8,10-dodecatetraenamide(2), (2E, 4E, 8Z, 10Z)-N-isobutyl-2,4,8,10-dodecatetraenamide(3), cerotic acid(4), hyxacosyl alcohol(5).
  
  
  CONCLUSIONS
  Compounds 1,4 and 5 were obtained from the plant for the first time.
