Abstract
This work aimed to assess the richness of the food halophytes Crithmum maritimum and Inula crithmoÑdes on phenolics and essential oils (EOs) and to evaluate the antioxidant and antibacterial potential of these metabolites. Results displayed that extract of I. crithmoÑdes possesses considerable contents of phenolic compounds (14.1 mg GAE.gâ1 DW) related to important antioxidant activities (IC50 = 13 μg mlâ1 for the DPPH test) as compared to C. maritimum. C. maritimum EOs composition is dominated by oxygenated monoterpenes, while I. crithmoÑdes one is mainly consisted by monoterpene hydrocarbons. EOs have low antioxidant activity as compared to acetone extracts; nevertheless, they show best antimicrobial activity. A significant variability is also depicted between the provenances of each species and depended on the chemical nature of antioxidant and antibacterial molecules as well as the used tests.
