Abstract

By DPPH● radical scavenging method, the antioxidant activity of the total hydroethanol and hydroacetonic extracts of Palisota
hirsuta (Commelinaceae), Mallotus oppositifolius (Euphorbiaceae), Ocimum gratissimum (Lamiaceae), Glyphaea brevis (Tiliaceae), four plant species from the Ivorian pharmacopoeia have been evaluated against two references (vitamin C and quercetin). The median
concentration (CR50) defined as the concentration of the extract necessary to reduce 50 % of the initial concentration of the DPPH●
radical, has been used as a parameter to evaluate the efficiency of the extracts in relation to the DPPH●. The results obtained in this work indicate that the crude hydroethanolic extract of Mallotus oppositifolius leaves has the best antioxidant activity (CR50=200.7±0.2 μg/ml) among all the extracts studied. However, this extract is less effective than vitamin C (CR50=136.2±0.3 μg/ml) but more effective than quercetin (CR50=222.1±0.2 μg/ml).
