Analytical characterization of industrial essential oils from fruits and leaves of C. aurantifolia tan. and C. latifolia swing. / Ivana Bonaccorsi in The journal of essential oil research, Vol. 23 N° 5 (Septembre/Octobre 2011)

Type de document : texte imprimé Auteurs : Ivana Bonaccorsi, Auteur ; Paola Dugo, Auteur ; Luigi Mondello, Auteur Année de publication : 2012 Article en page(s) : pp. 68-79 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : C.  aurantifolia  tan  C.  latifolia  swing  Peel  and  leaf  lime  oils  Volatiles  Non-volatiles  Enantiomeric  ratios  EsGC  GC/MS  MDGC  HPLC Index. décimale : 646 Résumé : The physicochemical indices, the composition of the volatile fraction, the enantiomeric ratios of some volatile components and the oxygen heterocyclic fraction of cold-pressed Key lime oils (types A and B), Persian lime oils, and petitgrain lime oils are reported. The volatile fraction of cold-pressed Persian lime oil is characterized by a higher content of limonene, γ-terpinene and esters and a lower content of β-pinene, sesquiterpene hydrocarbons, alcohols and aldehydes than cold-pressed Key lime oils. In petitgrain oils the oxygenated compounds are present at levels higher than the peel oils. Oxypeucedanin, probably due to the extraction technology, was almost absent in cold-pressed Key lime type A, while it is present in cold-pressed Key lime type B and in Persian lime oil. The en-separation was performed by direct enantioselective GC (esGC) and by multidimensional GC (MDGC) to obtain the most appropriate antiomeric separation of all the components analyzed. The enantiomeric excess of S-(-)-α-pinene, 1S,4R-(-)-camphene, S-(-)-β-pinene, S-(-)-sabinene, and R-(-)-β-phellandrene are lower in cold-pressed Persian lime oil than in Key lime oils.

Characterization of oils from the fruits, leaves and flowers of the bitter orange tree / Giovanni Dugo in The journal of essential oil research, Vol. 23 N° 2 (Mars/Avril 2011) 

Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 2 (Mars/Avril 2011) . - pp. 45-59 Titre : Characterization of oils from the fruits, leaves and flowers of the bitter orange tree Type de document : texte imprimé Auteurs : Giovanni Dugo, Auteur ; Ivana Bonaccorsi, Auteur ; Danilo Sciarrone, Auteur Année de publication : 2011 Article en page(s) : pp. 45-59 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Citrus  aurantium  L.  Essential  oil  Neroli  Petitgrain  Composition  Enantiomeric  distribution  Oxygen  heterocyclic  compounds  GC  GC/MS-LRI  Chiral  GC  RP-HPLC Index. décimale : 646 Résumé : The bitter orange tree is used to obtain different products: essential oil cold pressed from the peel of the fruit, the neroli distilled from the flowers, the petitgrain distilled from the leaves and twigs, and different other products obtained by solvent extraction or by hydrodistillation. All these products are much appreciated for their odor properties. Their analytical characterization is important for the Identification of quality parameters, and considering their commercial value, it is important to determine their composition. This study is meant to determine differences between Italian and Egyptian cold-pressed, neroli and petitgrain oils, and gives useful information on the composition of the essential oil obtained from the whole crushed fruits. The composition of all the samples was studied by different analytical techniques to determine the volatile fraction, the enantiomeric distribution of some volatiles (by GC, GC/MS and esGC, respectively) and the oxygen heterocyclic fraction by RP-HPLC.
