Abstract
This study was conducted in the years (2019-2020) to know the mineral compositions of the leaves of L. nobilis L. in two geographically and climatically different sites: Kassab in Lattakia and Al-Ghab in Hama by Atommic absorbtion device (Spectroghotometer). The results have shown that the percentages of some macro- and micro-elements of the powder of Laurus leaves for the two sites were as follows: Zn (27.76-41.97) mg/kg, Fe (160.32-195.95) mg/kg, Mn (30.07-30.19) mg/kg, Cu (12.54-20.43) mg/kg, Pb (7.01-8.01) mg/kg, Cr (1.73-2.48) mg/kg, Cd (0.32-0.33), Ni (5.97-6.01) mg/kg, As (2.82-2.96) mg/kg and Mg (0.16-0.175) mg/kg, whereas no presence of Co in Laurus leaves.
