Comparison of microwave-assisted hydrodistillation and hydrodistillation methods for the fruit essential oils of foeniculum vulgare / Müberra Koşar in The journal of essential oil research, Vol. 19 N°5 (Septembre/Octobre 2007) 

Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°5 (Septembre/Octobre 2007) . - pp. 426-429 Titre : Comparison of microwave-assisted hydrodistillation and hydrodistillation methods for the fruit essential oils of foeniculum vulgare Type de document : texte imprimé Auteurs : Müberra Koşar, Auteur ; Temel Ozek, Auteur ; Mine Kürkçüoglu, Auteur Année de publication : 2007 Article en page(s) : pp. 426-429 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Foeniculum  vulgare  Apiaceae  Fennel  Microwave-assisted  hydrodistillation  Hydrodistillation  Essential  oil  composition  (E)-anethole Résumé : Microwave-assisted hydrodistillation (MWHD) and hydrodistillation (HD) were carried out for the analysis of volatile components in whole and ground fruits of Foeniculum vulgare Miller (fennel). Fruits were distilled using a microwave oven modified to fit a Clevenger-type apparatus. The effect of microwave energy on the yield and composition of the essential oil was investigated against the classical hydrodistillation. All the essential oils were analyzed by GC-FID and GC/MS. (E)-anethole was found as the main compound in the oils of both whole and ground materials (82.2–86.8%) using the two methods. Methyl chavicol (4.0–4.9%) and limonene (2.2–4.9%) were also found in fennel oils obtained by HD and MWHD. The amounts of identified components in the oils obtained from whole and ground fennel fruits were not affected significantly by microwave energy except for limonene.
