Authors: Sabira Bi M. A. Shaikh, Anurag Naik

Abstract: Eleusine indica L.commonly known as the Indian goosegrass, wire grass or crowfoot grass belonging to Poaceae or Gramineae family was scrutinized in this study. The leaf blades were studied to observe the appearance of Phytolith structures which are microscopic silica bodies produced by many grasses which aids in their physical support. The extraction of silica was accomplished by acid treatment of these leaves in two cycles for 16 hours at 80°C each cycle. The oxidation process of synthesized silica was carried out using Hydrogen peroxide for 16 hours at 80°C to produce silicon dioxide (SiO2). The characterization studies were processed using X-ray diffraction, scanning electron microscope and energy dispersive X-ray (SEM – EDX), Raman spectrometer, Fourier Transform Infra-red spectroscopy (FT-IR). The obtained results were interpreted and compared with the standard. The comparative observations were reported.
