Phytochemical Synthesis and Crystallization of Sucrose from the Extract of Gloriosa superba

Sucrose is a major commodity in worldwide. In half a century the progress towards the understanding of the chemistry, structure, physical and functional properties of the sucrose molecule have been rapid. It was crystallized from the hot methanol extract of the rhizome powder of Gloriosa superba by using slow evaporation method at room temperature. The synthesized sucrose crystal lattice parameters were characterized by single crystal X-ray diffraction analysis. The presences of organic functional groups in the grown crystal were identified by FT-IR and Micro Raman analyses. The optical parameter of the grown single crystal was analyzed by UV-visible spectroscopy and maximum absorption was occurred at 253 nm. In addition, HOMO, LUMO, Molecular Electrostatic Potential (MESP), non-linear optical and several thermodynamic properties were analyzed by the DFT calculations. The thermal degradation of the sucrose crystal was tested by Thermo Gravimetric/Differential Thermal Analysis (TG/DTA).
