Abstract
This work aimed to assess the richness of the food halophytes Crithmum maritimum and Inula crithmoїdes on phenolics and essential oils (EOs) and to evaluate the antioxidant and antibacterial potential of these metabolites. Results displayed that extract of I. crithmoїdes possesses considerable contents of phenolic compounds (14.1mg GAE.g⁻¹ DW) related to important antioxidant activities (IC₅₀ = 13 μg ml⁻¹ for the DPPH test) as compared to C. maritimum. C. maritimum EOs composition is dominated by oxygenated monoterpenes, while I. crithmoїdes 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.
