Antioxidant Activity and Chemical Composition of Essential Oil of Cupressus atlantica Gaussen
My Youssef Arjouni,
My A. El Fels,
The present study describes the volatile profile and antioxidant activity from leaves, woods
and cones of Cupressus atlantica Gaussen (Cupressaceae). The hydrodistillated essential oils of different
part were analyzed by GC and GC/MS. In the leaves essential oil fifty-one constituents were
identified representing 98.8 % of the oil. The main components comprising trans Muurola-4(14),5-diene (31.2 %), pinene (18.1 %) and α-phellandrene (6.78 %). Monoterpene hydrocarbons representing 81.09% and 89.01%, respectively
in the woods and cones essential oil, the major components are pinene (56.6 % - 54.55 %) and α:pinene (56.6 % - 54.55 %) and pα:hellandrene (7.1 % -
15.7 %). The simples were subjected to screening for their possible antioxidant activities by using 2,2-diphenyl-1-
picrylhydrazyl (DPPH) assay. The IC50 values of leave, wood and cone essential oils were found to be (1.13 ± 0.24, 3.42 ±
0.18 and 3.84 ± 0.38) mg/mL, respectively.
