Structural and Chemical Characterization of Rasaparpati w.s.r to X-ray Diffraction

Abstract

Background: Rasaparpati is one of the chaturvidha rasayana commonly used in Grahani disorder. The present study is concerned with the processing and chemical characterization of Rasaparpati. Methods: Kajjali was prepared by using purified mercury and Sulphur and Rasaparpati was prepared by melting of Kajjali in an iron ladle and pressing in between the banana leaves into a thin flake. Because of its wide utility, the high end techniques are used to identify the composition of the medicaments. X-ray Diffraction is a popular analytical technique which has been used for the analysis of both molecular and crystal structures, qualitative identification of various compounds, phase transitions etc. Results: Analysis of Rasaparpati through X-ray Diffraction showed that, the highest peak was observed for HgS (Metacinnabar). Peaks of free Sulphur were also seen. No free mercury peaks were found. The 2 -Theta scales of HgS were 26.377,30.557,43.790,51.808,54.201,63.628,70.075,72.215 with d-spacing 3.378,2.925,2.067,1.764,1.692,1.462,1.342,1.308 respectively, which is in the cubic form. Sulphur present at 2 -Theta scales 22.69,23.08,27.73, 28.67, 28.95,30.55,31.40 of d-spacing 3.91,3.85,3.21,3.11,3.08,2.92, and 2.84 respectively in orthorhombic form. Conclusion: Prepared Rasaparpati showed HgS peaks, free Mercury peaks were not detected.
