Antimicrobial activity of essential oils from aromatic plants grown in the mediterranean area / Luca Tommasi in The journal of essential oil research, Vol. 21 N° 2+ supplément vol.20 (Mars/Avril 2009+ supplément 2008) 

Public ISBD [article]  in The journal of essential oil research > Vol. 21 N° 2+ supplément vol.20 (Mars/Avril 2009+ supplément 2008) . - pp. 185-189 Titre : Antimicrobial activity of essential oils from aromatic plants grown in the mediterranean area Type de document : texte imprimé Auteurs : Luca Tommasi, Auteur ; Carmine Negro, Auteur ; Antonio Miceli, Auteur Article en page(s) : pp. 185-189 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Thymbra  capitata  Origanum  vulgare  subsp.  hirtum  Rosmarinus  officinalis  Satureja  cuneifolia  Lamiaceae  Essential  oil  composition  α-pinene  γ-terpinene  p-cymene  1,8-cineole  Linalool  Borneol  Thymol  Antimicrobical  activity Index. décimale : 646 Résumé : The chemical composition and antimicrobial activity of the essential oils isolated from four Lamiaceae [Thymbra capitata (L.) Cav., Origanum vulgare L. subsp. hirtum (Link) Ietsw., Rosmarinus officinalis L. and Satureja cuneifolia Ten.] harvested at three different vegetative stages, spontaneously growing in the South of Puglia, towards Gram-(+)ve and Gram-(-)ve bacteria and pathogenic yeasts were evaluated. The four oils were analyzed by GC-FID and GC/MS, and exhibited similarities and differences with respect to data reported in the literature. Specifically, T. capitata and O. vulgare subsp. hirtum oils were found to be rich in thymol (60.9–67.5% and 29.8–56.8%, respectively) and R. officinalis oil had large amounts of 1,8-cineole (8.0–51.3%) and α-pinene (3.9–31.4%). The composition of the oil of S. cuneifolia varied most of all, its main constituents being linalool (9.6–32.7%), borneol (12.9–24.0%) and α-pinene (9.5–11.7%). Each of the oils was found to possess some antimicrobial properties using the agar diffusion method. The effectiveness and behavioral specificity varied from one species to another, and within each species, in relation to the vegetative period and the microorganism tested. The most effective oils were those of O. vulgare subsp. hirtum and T. capitata. The latter was also biologically active towards P. aeruginosa which was not sensitive to either R. officinalis or S. cuneifolia oils.

Essential oil of melissa romana (Miller) grown in southern apulia (Italy) / Antonio Miceli in The journal of essential oil research, Vol. 18 N° 5 (Septembre-Octobre 2006) 

Public ISBD [article]  in The journal of essential oil research > Vol. 18 N° 5 (Septembre-Octobre 2006) . - pp. 473-475 Titre : Essential oil of melissa romana (Miller) grown in southern apulia (Italy) Type de document : texte imprimé Auteurs : Antonio Miceli, Auteur ; Carmine Negro, Auteur ; Luca Tommasi, Auteur Année de publication : 2006 Article en page(s) : pp. 473-475 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Melissa  romana  Lamiaceae  Essential  oil  composition  β-caryophyllene  Cumene  β-pinene  Citral Résumé : The composition of the essential oil obtained from flowering tops of Melissa romana Miller wild grown in Southern Apulia (Italy) was investigated by GC and GC/MS. More than 90% of the compounds were characterized. β-Caryophyllene (15.8%), cumene (14.0%), β-pinene (12.0%) and citral (neral + geranial, 12.0%) were the major constituents of the oil.
