  The study of the protective effects of Sacoglottis gabonensis stem bark extract on the peroxidative deterioration of some common stored vegetable oils in Maiduguri over a period of time was carried out in comparison with vitamins C and E. Lipid peroxidation was monitored as lipid hydroperoxide carbonyls and lipid aldehydes concentrations on a time course basis over a period of 35 days in the vegetable oil test free and their respective antioxidant treated test samples. The treatment with the bark extract reduced the rate of formation of malondialdehyde and malonaldehyde at a rate that compared favourably with the inhibitions obtained with the antioxidants, vitamins C and E. The mechanism of inhibition of the observed anti-oxidant action of the bark extract appeared to be by inhibition of propagation of lipid peroxidation. Results obtained seemed to have confirmed earlier reports that the bark extract could find ready application as a nutritional antioxidant additive.

  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.
