Wolf. (Apiaceae) are reported to have a wide range of biological activities such as antibacterial and antidiarrheic activity. The in vitro antibacterial activity of the oil was evaluated by Disc diffusion method against several strains of bacteria, and this activity was shown to be very strong against most of the tested microorganisms, especially Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, and Enterococcus faecalis ATCC 29212. The MIC was also carry out and Bacillus subtilis ATCC 6633 (vegetative form) resulted to be the most sensitive microorganism with a MIC value inferior of 6.25 mg/L. The essential oil was analyzed by GC and GC/MS. The main components were thymol (53.2%), γ-terpinene (19.4%) and p-cymene (10.6%).

Composition and in vitro antimicrobial activities of the essential oils of two populations of thymus numidicus poiret. / Hocine Laouer in The journal of essential oil research, Vol. 21 N° 4 (Juillet/Août 2009)

Type de document : texte imprimé Auteurs : Hocine Laouer, Auteur ; Nacira Boulaacheb, Auteur ; Salah Akkal, Auteur Article en page(s) : pp. 374-377 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Thymus  numidicus  Lamiaceae  Essential  oil  composition  Thymol  Antimicrobial  activity Index. décimale : 646 Résumé : We investigated the chemical composition and the antibacterial activity of the essential oils of two populations of Thymus numidicus Poiret. differentiated by the color of the flowers. Forty-two compounds were identified by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS), representing more than 97% of the oil. The main components of both oils were thymol (59.0%, 68.0%), γ-terpinene (8.5%, 4.2%), p-cymene (5.8%, 4.5%), carvacrol (3.7%, 4.2%) and α-pinene (5.3%, 3.5%) (purplish-white and violet varieties, respectively). The oils exhibited promising activity in the disc diffusion antibacterial assay.
