[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 seasonal and even the number of hours that enable plants to be exposed to sunlight, may influence the phytochemistry of the plant since some compounds may be accumulated at a particular period to respond to environmental changes. Objectifs The seasonal variation of the essential oil extracted from the aerial parts of Artemisia herba alba growing in eastern Morocco (Taforalt) has been studied.

[more ▼] The present study describes the phytochemical profile Antioxidant and cytotoxicity activity of Lavandula dentata essential oil, collected in eastern Morocco (Taforalt). The sample of essential oil was obtained from the aerial parts of the plant by hydrodistillation and analyzed by GC–MS. The in vitro cytotoxicity of the oil on the cancer cell lines PC-3 (prostate), V79 (fibroblaste) and normal P388D1 (murine macrophage) was examined. We have shown that the oil had negligible cytotoxic effects against all cell lines tested. The oil was also found to possess antioxidant activity as demonstrated by the 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical method. Lavandula dentata essential oil has promising potentials for incorporation into various food, cosmetic and pharmaceutical products for which a natural aroma, colour, antioxidant and antimicrobial additive is desired.

[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.
