ABSTRACT

The aim of the present work is to characterize the phytochemistry and antioxidant activity of the cone, branch and needle essential oils of Cedrus atlantica growing in Khenchla, east montain region of Algeria. The chemical constituents of the essential oils obtained from the cones, branches and needles of the species were analyzed by gas chromatography coupled with mass spectrometry (GC-MS). Cis-?-Bisabolene (19.57%) was the main component of branch and needle oils followed by Perhydrofarnesyl acetone (4.74%) and Spathuleno (4.54%). Cone oils contained ?-pinene (46.613%) besides ?-pinene (9.698%) and D-limonene (4.351%). Moreover, the antioxidant activity was assessed using DPPH and Hydroxyl radical scavenging assays. It was found that the essential oils have a significant antioxidant effect when tested by the two methods but it is less effective than vitamin C.
