摘要：In this study, the flowering plant of syzygium cumini was used. X-ray fluorescence (XRF) and X-raydiffraction (XRD) were used to investigate the structure of the leaves and barks of syzygium cumini. The XRD resultswere indicated that the structures of both leaves and bark were amorphous. The XRF results indicated that both leavesand barks contained Potassium (K), Calcium (Ca), (Ti), and Magnesium (Mn), Iron (Fe), Copper (Cu), Zinc (Zn),Zernike (As), Lead (Pb), Barium (Br), Strontium (Sr). The optical properties of syzygium cumini were carried outusing Fourier Transformation infrared spectroscopy (FTIR) and Ultra violet spectroscopy (UV). The FTIR spectrashowed a broad and strong absorption band in the range (685-1638) cm–1, and these absorptions were assigned to thedifferent stretching vibrations. The absorption for bark and leave was found to be 2.45 and 2.52 a u, while the wavelength was found to be 277.4 and 277.5 nm, respectively. The energy band gap is calculated and found to be 5.017 and4.67 eV, for bark and leave, respectively
