Exploring and evaluating the phenolic profile and antioxidant properties of the Algerian wild carrot Daucus carota subsp. maximus aqueous extract

This study presents, for the first time, the phenolic profile of Daucus carota subsp. maximus aqueous extract and evaluates its antioxidant properties using various in vitro assays. The aqueous extract contained significant polyphenol and flavonoid contents (99.00 µg GAE/mg E and 43.06 µg QE/mg E, respectively). Additionally, LC-ESI-MS/MS analysis made it possible to identify and quantify 19 phenolic compounds, with trans-ferulic acid as the predominant compound (1.460 mg/g). Moreover, the aqueous extract exhibited antioxidant effects in all assays, with IC50 and A0.5 values less than 200 µg/mL except for Phenanthroline reducing power and SNP assays.
