The phenolic contents of metabolic extracts of WarioniasaharaeL leaves, flowers and stems from Morocco were measured in this work. The antioxidant activities of these extracts were also evaluated. The leaves methanolextract afforded the highest yield (28.2 g/100 DW) while the lowest yield was obtained from the stems (5.6 g/100 DW). Total phenolic and flavonoid contentswere (73.0 ± 0.52 mg Gallic acid/ g extract) and (2.02 ± 0.22 mg quercetin equivalents (QE)/g extract). Moreover, flowers methanol extract has remarkable DPPH radical scavenging activity with IC50 = 31.45 ?g/mL.A result indicates that methanol flower extracts of W.saharaeL. have marked amount of total phenols which could be responsible for the antioxidant activityand could be further investigated by detailed phytochemical study.
