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.
