Abstract:
The concentrations of (Zn, Fe, Mn, Ni, Cu and Cd) were determined in the leaves of Adhatoda schimperiana, Phytolacca dodecandra, and Calpurnia aurea. Zinc, Fe and Mn were found in the
range of (in mg kg−1): 179 to 342, 163 to 255 and 14 to 198,
respectively. Copper was not detected in C. aurea, Nickel was
found only in A. schimperiana 21 mg kg−1) and Cd only in
P. dodecandra (5 mg kg−1). Leaves of P. dodecandra contained
about two times of Zn and four times of Mn than that of the other
plant species. The higher amount of Zn in P. dodecandra, can be
ascribed to its beneficial effect in the treatment of hepatitis.
