Abstract:

Objective: This study aims to establish the quantitative organic composition, and to appreciate the antioxidant potential of the essential oils (EOs) from the fresh and dried leafy stems of Origanum syriacum acclimated in Côte d’Ivoire. Methods: The chemical composition determined by GC (Ir), GC-MS and 13C-NMR showed that the species belongs to the carvacrol family. The antiradical activity was evaluated with respect to the radical DPPH●, (2,2-diphenyl-1-picrylhydrazyl). Results: In total 31 compounds have been identified accounting for 98.1-99.4% of the total composition. The major compound was carvacrol (61.5-69.8%) following by γ-terpinne (11.3-14.5%). In vitro antioxidant test showed that essential oil from O. syriacum had an antioxidant potential nevertheless lower than that of ascorbic acid (vitamin C). Conclusion: This study highlights chemical composition of the essential oil from O. syriacum and an interesting antioxidant potential. These data would justify various traditional uses in therapeutic.
