Abstract
) ranged from 324.55 ± 0.66 to 980 ± 0.62 μg/ml for DPPH and from 107.85 ± 0.19 to 890.74 ± 0.17 μg/ml for ABTS. FTIR spectroscopic analysis has revealed different characteristic peak values with various functional groups in the extracts such as amide, alcohol, phenol compounds. In general, the organic and aqueous extracts of M.vulgare L. that were harvested from Oulad Daoud Zkhanin were richer in secondary metabolites, and showed higher concentrations of polyphenol, flavonoids and tannins. In addition, they revealed a higher antioxidant capacity than the extracts of M. vulgare L.from the Cape Three Forks. Overall this study highlighted the potential benefits and richness of M.vulgare L. harvested from the two study areas and suggested it as a potential source of natural antioxidants that could be used in the food and pharmaceutical fields.
