[Lipid compounds from Echinacea purpurea].

OBJECTIVE: To study the lipid constituents from Echinacea purpurea. METHOD: The compounds were isolated by chromatography method and the structures were identified on the basis of spectral analyses. RESULT: 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). CONCLUSION: Compounds 1,4 and 5 were obtained from the plant for the first time.
