The flowering plants Zizz'phusspina- christi -localy known as sidr-was used. The X-Ray Fluorescence (XRF) results indicated that, the local sidr (leaves) are contained Potassium (K), Calcium (Ca), Titanium(Ti), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Lead (Pb), Bromine (Br), Rubidium (Rb), Strontium (Sr), Zirconium (Zr) and Niobium (Nb). The Persian Sidr (leaves) are contained Potassium (K), Calcium (Ca), Titanium(Ti), Manganese (Mn), Iron (Fe), Copper (Cu), Zinc (Zn), Lead (Pb), Bromine (Br), Rubidium (Rb), Strontium (Sr), Zirconium (Zr) and Niobium (Nb), we note that Calcium (Ca) has highest Concentration and Niobium (Nb) has least Concentration. The Fourier Transfonn Infra Red (FTIR) spectmm of local sidr (leaves) showed functional groups of acid chlorides, alcohols, carboxylic acid, amides and amines. In Persian sidr FTIR spectra showed ketones, carboxylic acid, alkenes and amines, from Ultra Violet(UV) we found the leaves of sidr are insulator material.enZizz'phusspina- christi - PHYSICAL PROPERTIESThesis
