To prepare the Praval bhasma (PB) and to perform its characterization. 


The preparation was performed strictly as per method prescribed in Ayurvedic formulary of India followed by preliminary tests including Nischandratva, Rekhapurnatvam, Varitaramtavm, Nisvadutvam and Amla pariksha. The physicochemical characterization was done with the use of instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X ray diffraction (XRD), and energy dispersive X-ray (EDAX). 


The FTIR bands appearing in final product spectra showed a significant shift in infrared vibration frequency as well as intensity when compared with the raw material, which was indicative of formulation of bhasma. The XRD analysis revealed that raw material contained CaCO3 whereas in case of final product of bhasma, CaO was identified. SEM analysis revealed the difference in particles size of bhasma (10-15 μm) and raw material (100-150 μm). The EDAX analysis showed presence of different concentration of carbon in both the samples. 


It may be concluded that modern analytical techniques may be involved to evaluate the quality aspects of PB. The findings of the present research work may be helpful for further formulation and standardization of PB in routine analysis.
