ABSTRACT

The concentration and health risk assessment of some microelements in commonly consumed antidiabetic medicinal plants in Mubi North Local Government Area, Adamawa State, Nigeria were analysed using Atomic Absorption Spectrometry (AAS). Four anti-diabetic plants were analyzed for concentrations of Lead (Pb), Copper (Cu), Iron (Fe), Chromium (Cr), Zinc (Zn), Manganese (Mn) and Cadmium (Cd) respectively, in the stem bark and leave of the following medicinal plants: (Euphobia Hirta, terminallia Avicenioides, Daniella Oliveri, and Laptadania Hastata).The findings of the study revealed that the investigated antidiabetes medicinal plants contained varying concentrations of elements such as Cu, Fe ,Cr, Zn, Mn and Cd and are within the permissible limits of (WHO), except Pb and Cr which were below detection limits. By calculating risk quotient based on the estimated daily intake (EDI) of 100g the health risk associated with the consumption of the analyzed medicinal plants preparations was also evaluated. However, all the anti-diabetic plants shows a risk quotient (RQ) value less (<1) than one. The potential health risk of the concentration of micro elements in the medicinal plants using 100g as daily intake dose for both adults and children are negligible. Therefore, the consumption of these studied medicinal plants poses no health risk and is safe.
