In vitro antioxydant activity and total phenolic content of extracts from the endemic <i>Argania spinosa</i> (L.) Skeels from Algerian Sahara

Abstract

The BuOH fractions prepared from 80% MeOH extract of the leaves from the endemic Saharan tree Argania spinosa (L.) Skeels exhibited the most potent antioxidant capacity ( IC₅₀ = 2.41 ± 0.38 µg/mL for DPPH and 7.95 ± 0.54 µg/mL for superoxide anion radical), compared to the EtOAc and CHCl₃ fractions. The results showed that BuOH extract fraction exhibited a strong antioxidant activity and had the most potent scavenging abilities which may be correlated to the presence of Phenolic compounds.
