Results: All the extracts showed significant antioxidant activities and contained important
levels of phenols. The ethanol extract (0.3 mg/mL) from Sefrou showed the greatest
antioxidant capacity in the three systems of assay, which was probably due to its high content
of polyphenols (274.39±6.94) mg gallic acid equivalent/g dry extract. Total flavonoid content
was found equal for all extracts.
