Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 1 (Janvier-Fevrier 2005) . - pp. 36-40 Titre : Preliminary investigation on the volatile constituents of croton sonderianus muell. arg. : Habitat, plant part and harvest time variation Type de document : texte imprimé Auteurs : Regina C.M. Dourado, Auteur ; Edilberto R. Silveira, Auteur Année de publication : 2006 Article en page(s) : pp. 36-40 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Croton  sonderianus  Euphorbiaceae  Essential  oil  composition  α-pinene  Myrcene  1,8-cineole  β-phellandrene  Limonene  Bicyclogermacrene  Cyperene  β-caryophyllene  β-elemene  Spathulenol Résumé : The chemical composition of the oils obtained from the leaves of Croton sonderianus from different regions of Ceará State (northeast of Brazil) from the same population at different times were analyzed by GC/MS: α-pinene, myrcene, 1,8-cineole, β-caryophyllene and spathulenol. Representative constituents present in almost all analyses were used for comparison. The oils from different plant parts (leaves, flowers, roots and trunk barks) of a same specimen were also analyzed: β-phellandrene (20.4%, leaves), bicyclogermacrene (29.1% and 17.7%, flowers and leaves, respectively), β-elemene (17.8% and 22.8%, flowers and trunk bark, respectively), cyperene (14.2%, roots) and germacrene D (12.8%, trunk bark) were the major components.
