İsmail Kirbaşlar, Auteur ; Ismail Boz, Auteur ; F. Gülay Kirbaşlar, Auteur Année de publication : 2006 Article en page(s) : pp. 525-543 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Citrus limon paradisi Rutaceae Lemon oil Grapefruit Essential composition Limonene Résumé : Lemon [Citrus limon (L.) Burm. f.] and grapefruit (Citrusparadisi Macf.) peel oils were obtained by cold-pressing lemon and grapefruit peels. The oils were analyzed by high-resolution gas chromatograph (HRGC) and high-resolution gas chromatography/mass spectrometer (HRGC/MS). In total, 42 and 27 components have been identified in lemon and grapefruit oils, respectively. Lemon oil showed a high content of monoterpene hydrocarbons (89.9%) with limonene (61.8%), γ-terpinene (10.6%) and β-pinene (8.1%) being the first three major components. Similarly, grape-fruit oil was characterized by its higher content of monoterpene hydrocarbons (96.4%) of which limonene (92.5%) and myrcene (2.6%) were the first two major components. Grapefruit oil contained a lower amount of sesquiterpene hydrocarbons, aldehydes, alcohols and esters than that in lemon oil.

Volatiles in Turkish clementine (Citrus clementina Hort.) peel / Ş. İsmail Kirbaşlar in The journal of essential oil research, Vol. 24 N° 2 (Avril 2012)

İsmail Kirbaşlar, Auteur ; Aslı Gök, Auteur ; F. Gülay Kirbaşlar, Auteur Année de publication : 2012 Article en page(s) : pp. 153-157 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Rutaceae Citrus clementina Hort. ex Tan. Cold-pressed peel oil Supercritical CO2 extract Limonene Résumé : The peel extract of clementine (Citrus clementina Hort. ex Tan.) grown in Turkey was obtained by cold pressed (CP) and supercritical CO2 extraction (SFE) methods. The chemical compositions of the volatile extract samples were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). In total, sixty-nine components have been identified corresponding to the (99.8%) of the whole volatiles in both samples. CP extraction led to lower amount of oxygenated compounds (3.7%) than the SFE extraction (4.2%); among these, carbonyls were predominant (2.09–2.10%) followed by alcohols (1.32–1.60%) and esters (0.12–0.40%). The main component is limonene (88.12–89.28%) followed by myrcene (4.64–3.77%). The oxygenated compounds present at higher levels are linalool (1.02–1.24%) and decanal (0.71–0.72%).
