Hydrodistillation kinetic and antibacterial effect studies of the flower essential oil from the tunisian ridolfia segetum (L.) / Hichem Ben Jannet in The journal of essential oil research, Vol. 19 N°3 (Mai/Juin 2007) 

Public ISBD [article]  in The journal of essential oil research > Vol. 19 N°3 (Mai/Juin 2007) . - pp. 258-261 Titre : Hydrodistillation kinetic and antibacterial effect studies of the flower essential oil from the tunisian ridolfia segetum (L.) Type de document : texte imprimé Auteurs : Hichem Ben Jannet, Auteur ; Zine Mighri, Auteur Année de publication : 2007 Article en page(s) : pp. 258-261 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Ridolfia  segetum  Apiaceae  Essential  oil  composition  Myristicin  Dillapiole  Antibacterial  activity Résumé : The flower oil of Ridolfia segetum (L.) Moris of Tunisian origin was analyzed by GC and GC/MS. The main constituents of the oil were myristicin and dillapiole, the amounts of which varied depending upon the length of time the flowers were hydrodistilled. The contents of myristicin and dillapiole varied from 13.1–31.5% and 29.5–85.4%, respectively. Oil samples (fractions) were taken every 10 min from 10 to 150 min. Each fraction was screened against three Gram-positive and three Gram-negative bacteria. It was found that the antibacterial activity of the fractions was directly related to their proportions of monoterpenols and phenolic derivatives.

Studies of the essential oil composition, antibacterial and antifungal activity profiles of frankenia laevis L. from Tunisia / Mohamed A. Mahjoub in The journal of essential oil research, Vol. 22 N° 4 (Juillet/Août 2010)

Forty-four compounds were identified, representing 91.5% of the oil constituents. Hexadecanoic acid was the major compound (19.8%), followed by methyl linoleate (16%), (E, E)-farnesyl acetate (9.5%), (E)-nerolidol (8.9%) and benzyl benzoate (6.8%). Minimum inhibitory concentrations, minimum bactericidal concentrations and inhibition zone diameters against gram-positive bacteria, gram-negative bacteria and phytopathogenic fungi were determined. Essential oil was particularly effective against Staphylococcus aureus, Micrococcus luteus and Salmonella typhimurium, nevertheless no antifungal activity was detected at the tested concentrations.
