Essential oil was obtained in a yield 1.1%, w/w, by steam distillation of Elionurus tristis leaves from Madagascar. The chemical composition was analyzed qualitatively and quantitatively by GC-MS and GC-FID, respectively. To the best of our knowledge, this is the first chemical analysis of this essential oil. Seventy-three compounds were identified, corresponding to 94.9% of the total essential oil. The principal compounds were sesquiterpenes and the more represented were β-gurjunene (18.4%), neoclovene (15.8%) and nootkatone (10.4%). Through a comparative study, we observed a large variability between the components of E. tristis essential oil and those from others species of the same genus. Evaluation of the antioxidant (ABTS and DPPH assays) and anti-tuberculosis activities of the essential oil showed weak antioxidant potency but an interesting anti-tuberculosis activity with a MIC of 32 mg/L. This activity prompted us to evaluate individually the major components for the treatment of tuberculosis.
