The ethanolic extract has a higher polyphenol dose followed by the aqueousextract (1.217 mg/g and 0.245 mg/g). The antioxidant activity results howed that the aqueous extract has the highest activity compared to ascorbic acid IC50=0.0016 followed by the ethanolic extract IC50=0.11frApiaceae, Daucus crinitus, activité antioxydante, polyphénols, extrait aqueux EA, extrait éthanolique EEVALORISATION CHIMIQUE ET BIOLOGIQUE DES EXTRAITS D’UNE APIACEAThesis
