Analysis of the volatile components of onosma echioides (L.) L. var. columnae lacaita growing in central Italy / Filippo Maggi in The journal of essential oil research, Vol. 21 N° 5 (Septembre/Octobre 2009)

L. var. columnae lacaita growing in central Italy Type de document : texte imprimé Auteurs : Filippo Maggi, Auteur ; Bruno Tirillini, Auteur ; Sauro Vittori, Auteur Article en page(s) : pp. 441-447 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Onosma  echioides  var  Columnae  Boraginaceae  Essential  oil  composition  Phytol  Hexadecanoic  acid  Hexahydrofarnesyl  acetone Index. décimale : 646 Résumé : Volatile components obtained by hydrodistillation from the aerial parts (leaves and flowers) of Onosma echioides (L.) L. var. columnae Lacaita (Boraginaceae family) growing wild in central Italy (Marche, Umbria and Abruzzo regions) were investigated by GC and GC/MS for the first time. Sixty-four volatile components were identified: hexadecanoic acid (3.2–33.8%) and phytol (7.3–15.2%) were predominant in the flower oils, while phytol (36.5–54.5%) and hexahydrofarnesyl acetone (7.1–12.1%) were the major components in the leaf oils. Alkanes, fatty acids and aldehydes constituted the major fraction in the flower oils, while oxygenated diterpenes and ketones were predominant in the leaf oils. Phytol was isolated by flash chromatography and its identity was confirmed by IR, 1H-NMR and 13C-NMR spectra. Variation of the volatile components in the six populations of O. echioides var. columnae, due to genetic and geographic factors, was analyzed by cluster analysis.

Essential oil composition of ephedra nebrodensis tineo ex Guss. subsp. nebrodensis from central Italy / Filippo Maggi in The journal of essential oil research, Vol. 22 N° 4 (Juillet/Août 2010)

Fifty-nine components were identified, representing 89.3% of the oil under study. The oxygenated monoterpenes gave the highest contribution (33.0 %), and citronellol (29.7%) was the main component of this fraction. Esters were the second most abundant group of components (18.8%) with ethyl hexadecanoate (9.5%) as the main representative in this fraction. Qualitative and quantitative composition of the oil was discussed in order to support the actual botanical discrimination from E. major Host, so far exclusively morphologically based.

Forty-six components were identified, representing 91.5% of the oil. The sesquiterpene fraction gave the highest contribution (68.4%), whilst monoterpenes amounted to 22.5%. The major constituents were β-pinene (11.9%), α-humulene (7.4%), β-caryophyllene (6.5%) and α-selinene (5.4%). Results confirm that hybridization may generate novel secondary chemistry in plants.
