Public ISBD [article]  in The journal of essential oil research > Vol. 17 N° 3 (Mai-Juin 2005) . - pp. 286-288 Titre : Volatile constituents of piperaceae from Santa Catarina, Brazil : Essential oil composition of piper cernuum vell. and peperomia emarginella (sw.) C. DC. Type de document : texte imprimé Auteurs : Aluízio M. De Abreu, Auteur ; Inês Ma Costa Brighente, Auteur ; Eliane M. De Aguiar, Auteur Année de publication : 2006 Article en page(s) : pp. 286-288 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Piper  cernuum  Peperomia  emarginella  Piperaceae  Essential  oil  composition  Limonene  Decanal  β-dihydroaga-rofuran Résumé : The essential oil composition of two Piperaceae from the Itajaí Valley in Santa Catarina, Brazil, is described by means of GC and GC/MS analysis. Piper cernuum provided an oil constituted mainly by α-pinene (2.5%), β-elemene (2.6%), β-caryophyllene (4.4%), germacrene D (2.7%), β-dihydroagarofuran (31.0%), elemol (12.0%), 10-epi-γ- eudesmol (13.0%) and β-eudesmol (2.6%). Twenty-eight compounds representing 87.8% of the oil were identified. Peperomia emarginella provided the most interesting oil due to its pleasant and intense odor, where limonene (29.0%) and decanal (33.0%) accounted for 62.0% of the overall composition. Thirty-one compounds representing 94.4% of the oil composition were identified.
