Opis:
The essential oil from flowering Marrubium (Marrubium vulgare L.) an aromatic member of the Lamiaceae family, from Algeria, obtained by hydrodistillation, was analysed by GC/FID and GC/MS. The constituents were identified by their mass spectra and Kovats’ indices. Fivety (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). Essential oil of M vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Bacillus subtilis, Micrococcus luteus, Escherichia coli and Klebsiella pneumoniae.

Opis:
In previous work [1], the essential oil of the aerial parts of Marrubium vulgare L. obtained by hydrodistillation was analysed by gas chromatography coupled to mass spectrometry (GC-MS) in order to determine their chemical composition. Fifty (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97 %), Germacrene D-4-ol (9.61 %), α- pinéne (9.37 %), Phytol (4.87 %), Dehydro-sabina ketone (4.12 %), Piperitone (3.27 %), δ-Cadinene (3.13 %), 1-Octen-3-ol (2.35 %) and Benzaldehyde (2.31 %). In this study, the antioxidant properties of essential oil were examined. The results showed that this oil can be considered an effective source of antioxidants of natural origin. This is the first report on chemical composition of M. vulgare essential oil cultivated in Algeria and the original study on the antioxidant activity of M. vulgare essential oil. The antioxidant activity was investigated with one method: 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method.

The antioxidant activity of the oils was assessed by measurement of metal chelating activity, the reductive potential, the free radical scavenging (DPPH) assay. The antioxidant activity was compared with that of synthetic antioxidants: butylated hydroxyanisole (BHT) , and the essential oils . The results showed as the Essential oil of M vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Listeria monocytogene, Pseudomonas aeruginosa , Agrobacterium tumefaciens and Salmonella enterica.
