The samples were ground into powder using a
pulverizer and stored in an air tight bottle prior to use for analysis.
The ground samples were used for the analysis of proximate
composition and minerals content. After weighing 200 g,
each of the ground sample of the leaf, stem bark and root was
dissolved in 1000 mL each of deionised water, ethanol, methanol
and ethyl acetate and was kept in the refrigerator for 72 h
