Abstract
Essential oil components of the leaves of Thymus numidicus growing in Mila have been studied by gas chromatography mass spectrometry GC/MS to afford 60 Sixty compounds representing 94.0 % of the total oil and mainly represented by oxygenated monoterpenes,. The main constituents of the essential oil from the leaves were thymol (41.2%), β-cymene (12.9%), chlorocresol (11.2%), β-linalool (10.7%) and methyl thymol ether (3.3%). The antioxidant activity was evaluated by spectroscopic method, used for that free radical compound (DPPH) and in comparison with vitamin C as a standard. The essential oil showed a moderate activity against free radical compound (DPPH) 17.4% at 1M.
