%X Bioactive compounds in plants are associated with the reduction of
chronic diseases. The free radical scavenging activity of different extracts of
a medicinal plant, <i>Sclerocarya birrea</i>, has been investigated using the DPPH test, ABTS test and FRAP. Three extracts
were prepared from the leaves and bark: hydro-methanolic, hydro-acetonic and
aqueous. Phytochemical screening was carried out the standard methods followed
by the determination of the polyphenol by Folin-Ciocalteu method. The analysis
of variance (ANOVA) with the STATISTICA 7.1 and statistical significance was
set at p < 0.05. Evolution of percent inhibition (PI) as well as the IC50 of the extracts was obtained using the Origin Pro 8.5 software and Microsoft Excel. The results
show that the bark extracts are about twice as rich in polyphenols as the
leaves. With DPPH at 1.25 mg/mL, the bark has a PI of 91.04% ¡À 0.001% while
leaves, reach 99.80% ¡À 0.021%. As for the ABTS test, the bark extract reached
its maximum activity at 1.25 mg/mL with a
PI of 99.80% ¡À 0.003% while leaves extract
