The concentrations of essential macro and micro elements were determined using Energy Dispersive X-ray Fluorescence technique (EDXRF) being the most suitable instrument for the multi-element analysis in plant samples. Two macroelements (Ca and K) and seven microelements (Fe, Mn, Zn, Cu, Rb, Sr and Br) were analyzed in different parts (leaves, wood bark and roots) of Durio zibethinus Murr. The results revealed the levels of the two macroelements and seven microelements in Durio zibethinus leaves, wood bark and roots. The levels of elements in different plant parts were found not to be significantly different (p < 0.05). This study is based on the elemental concentration in different parts of studied plant and their biological roles on human physiology. And the findings show that the plant contains important elements for human metabolism and prevention or healing of diseases.
