Abstract: Antioxidants present in natural sources help to scavenge free radicals and thus provide health benefits. This study reports in vitro radical scavenging and antioxidant capacity of crude methanol and ethanol-water extracts of the fruits of Tetrapleura tetraptera and Parkia biglobosa. Total phenolic contents in Tetrapleura tetraptera were 147.82±1.36 and 130.33±1.04 mg GAE/g dry weight while that of Parkia biglobosa were 128.32± 0.49 and 127.23±0.11 mg GAE/g dry weight respectively. The total antioxidant capacity of the extracts ranges from175.52±4.66 (methanol) to 172.87±2.15 mg/g (ethanol/water) for Tetrapleura tetraptera and from 160.44±2.26 (methanol) to 157.31±1.90 mg/g (ethanol/water) for Parkia biglobosa. The antioxidant activities of both fruits determined by the 2,2’-diphenyl-1-picrylhydrazyl radical (DPPH) and the reducing power (RPA) assays produced concentration-dependent values comparable to that of ascorbic acid control. The results of the study showed that fruits of Tetrapleura tetraptera and Parkia biglobosa have strong radical scavenging and reducing capacities.
