In this study, Cedrus atlantica was investigated for their efficacies against MMP-13 inhibitory activity.
Plant material: The aerials parts of Cedrus atlantica were collected in August 2009 at Tichoukt (15 km in the south east of Boulmane) a mountainous region from Morocco.
Chromatographic (GC/MS & GC-FID) analysis: The chemical composition of leaf oil from Cedrus atlantica in Morocco was determined by GC- FID (TRACE GC-ULTRA S/N 20062969, Thermo Fischer) and GC-MS (TRACE GC-ULTRA S/N 20062969-PolarisQ S/N 210729, Thermo Fischer) equipped with TRIPLUS AS S/N 20063460 in the light of the following experimental protocol.
In this work, antibacterial activity of Cedrus atlantica oil was examined using different bacterial species.
Chemical composition of the essential oil: The compounds essential oil of Cedrus atlantica from Morocco is listed in order of their elution on the (TR5- CPSIL- 5CB column) (Fig.
The essential oil yield of Cedrus atlantica collected from region of Boulmane (Morocco) was 1.82%; it's relatively higher than other plants industrially exploited as a source of essential oils: Thymus (1%) (Imelouane et al., 2009), lavender (0.8-2.8%), menthe (0.5-1%), neroli (0.5-1%) and Laurel (0.1-0.35%) (Edward et al., 1987), Tetraclinis (0.22%) (Bourkhiss et al., 2000), Juniperus phoenicea (1.62%) (Derwich et al., 2010) and Lippia rotundifolia (0.01%) (Suzana et al., 2008).
