Total Phenolic Contents and Antioxidant Activity of Methanol Extract from Leaves, Flowers and Stems of Warionia saharae L. from Morrocco

Total Phenolic Contents and Antioxidant Activity of Methanol Extract from Leaves, Flowers and... AbstractThe phenolic contents of metabolic extracts of Warionia saharae L. leaves, flowers and stems from Morocco were measured in this work. The antioxidant activities of these extracts were also evaluated. The leaves methanol extract 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 contents were (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 μg/mL.A result indicates that methanol flower extracts of W. saharae L. have marked amount of total phenols which could be responsible for the antioxidant activity and could be further investigated by detailed phytochemical study. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Biologically Active Products from Nature Taylor & Francis
