Abstract: Studies on the effects of Sacoglottis gabonensis stem bark extract against lipid peroxidation and on the natural antioxidant defenses after phenylhydrazine-induced lipid peroxidation resulted in elemental determination of the bark extract. The data revealed that the bark extract contains copious amounts of core elements required in natural antioxidant defenses against peroxidation reaction as well as absence of heavy metals that elicite free radical formations. The bark extract can, thus, find ready application as an antioxidant as well as function in electrolyte balance controls.
