Artemisia arborescens L. is a medicinal and aromatic plant used in traditional medicine for its therapeutic properties to
treat lung diseases, gastrointestinal disorders, diabetes and inflammations. The leaves of A. arborescens L. were harvested
in Amizour, Cap Bouak and Sahel (Bejaia, Algeria) and their essential oils were analyzed by Gas Chromatography/Flame
Ionization Detector and Gas Chromatography/Mass Spectrometry. The main constituents were β-thujone in the essential
oil of Cap Bouak (59.8%), camphor in the volatile oil of Sahel (58.7%) and chamazulene in that of Amizour (31.4%). The
radical scavenging activity of these essential oils was evaluated against DPPH and ABTS radicals by calculation of IC50.
The best activity against DPPH and ABTS radicals were that of Sahel essential oil with IC50
DPPH = 133.0 μg/mL and
IC50
ABTS = 211.6 μg/mL. The Spearman test revealed no significant correlations between IC50
DPPH and the chemical
composition of the essential oil from A. arborescens L., while correlations with IC50
ABTS indicated that hydrocarbon
monoterpenes, oxygenated monoterpenes and hydrocarbon sesquiterpenes promote activity against ABTS radical. These
results can give prospects of using essential oils from A. arborescens L. as a natural adjunct in medicine formulations to
treat diseases caused by oxidative stress.
