ESSENTIAL OIL COMPOSITION AND ANTIMICROBIAL ACTIVITY OF ARTEMISIA HERBA-ALBA ASSO GROWN IN MOROCCO; ; et al in Banat's Journal of Biotechnology (2011), I(2), Volatile components of Artemisia herba-alba Asso essential oil obtained by hydrodistillation growing in eastern Morocco (Taforalt) were investigated by GC/FID and GC-MS. The major components were found to ... [more ▼] Volatile components of Artemisia herba-alba Asso essential oil obtained by hydrodistillation growing in eastern Morocco (Taforalt) were investigated by GC/FID and GC-MS. The major components were found to be camphor (43.07%), camphene (7.2%), 1,8-cineole (7.08%), filifolone (7.04%), borneol (4.88%), and bornyl acetate (3,79%).The essential oil has been tested for antimicrobial activity against Gram-negative and Gram-positive bacteria. Inhibition of growth was tested by the agar diffusion method. The minimal Inhibitory Concentration (MIC) was determined by the method of microtitration assay.

[more ▼] The essential oil from flowering Thyme (Thymis vulgaris L.) an aromatic member of the Lamiaceae family, from Morocco, obtained by hydrodistillation, was analysed by GC/FID and GC/MS. The constituents were identified by their mass spectra and Kovats’ indices. Forty three compounds consisting 97.85% of the total components were identified from the oil obtained with 1% yield. Among those, camphor (38.54%), camphene (17.19%), α-pinene (9.35%), 1, 8-cineole (5.44%), borneol (4.91%) and β-pinene (3.90%) were the major oil components. Essential oil of Thyme was evaluated for its antibacterial activities against six Gram-positive and Gram negative pathogenic bacteria: Staphylococcus aureus, S. epidermidis, Streptococcus sp., Pantoa sp. and Escherichia coli.
