The antioxidant capacity of the test extracts was first determined using the 2,2-Diphenyl-1-Picryl-Hydrazyl-Hydrate (DPPH) assay. By DPPH free radical scavenging activity, only a few extracts showed strong antioxidant activity. Among all, the antioxidant potential of Diospyros melanoxylon methanolic extracts was found to be higher. The presence of phenols and flavonoids in the test extracts could explain their high antioxidant activity. The anti-inflammatory efficacy of test extracts was also assessed using a carrageenan-induced paw edoema model.
