Authentication of bergamot essential oil by gas chromatography-combustion-isotope ratio mass spectrometer (GC-C-IRMS) / Luisa Schipilliti 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. 60-71 Titre : Authentication of bergamot essential oil by gas chromatography-combustion-isotope ratio mass spectrometer (GC-C-IRMS) Type de document : texte imprimé Auteurs : Luisa Schipilliti, Auteur ; Giovanni Dugo, Auteur ; Luca Santi, Auteur Année de publication : 2011 Article en page(s) : pp. 60-71 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : GC-C-IRMS  Bergamot  essential  oil  Citrus  bergamia  Risso  Quality  assessment  Stable  isotope  ratio  analysis  Linalool  Linalyl  acetate  Adulteration Index. décimale : 646 Résumé : The quality assessment of bergamot essential oils was established employing the gas chromatography-combustion- isotope ratio mass spectrometer (GC-C-IRMS) technique. An authenticity range was obtained investigating the carbon stable isotope ratio of genuine Italian bergamot essential oils (harvest period 2008–2009), in order to compare the GC-C-IRMS data of several industrial, commercial and foreign bergamot essential oil samples. Moreover, with the aim to test the efficiency and the sensibility of IRMS device, self-adulterated in laboratory bergamot oil samples were analyzed. The data were compared with those achieved by conventional enantioselective gas chromatography (Es-GC) and high resolution gas chromatography (GC-FID). Results of this work indicated that GC-C-IRMS was able not only to detect the presence of adulterants in the samples, but also to discriminate the bergamot oil samples according to their geographic provenance and the nature of the adulterants added.

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.
