Results on the concentration of each mineral are expressed as μg/g of dry powder of the aqueous leaf extracts of Zanha africana of three determinations and are in the second column; the amount of each mineral administered in μg based on its concentration in the plant’s extract is in the third column. This is compared with the recommended daily allowance shown in the last column. This is expressed per the average weight of each mouse. *Recommended daily allowance estimated from that of human beings stated in Strain and Cashman (2009) [60].
