Background:Vaikrānta has very important place in Rasa śāstra and is placed under Mahārasa and Upratna group. It has been mentioned that vaikrānta can be used in the place of diamond, which is a very precious stone and whose use is beyond the limit of the common man. Vaikrānta possesses pharmacological and therapeutic properties similar to diamond, but still very few researchers have worked on it.Aims and Objectives:The main aim of the present study is to analyze vaikrānta bhasma by employing various organoleptic methods mentioned in Ayurvedic science along with analysis as per tools available today.Settings and Design:In the present study, vaikrānta bhasma was prepared according to method mentioned in Rasa Ratna Samuccaya. Final product is prepared according to classical parameters described in Ayurvedic science.Materials and Methods:Ayurvedic scholars have described various parameters for the qualitative evaluation of vaikrānta bhasma, but all those are subjective in nature and cannot be evaluated numerically for reproducibility of the result. With this in mind, in the present study, tests as per Ayurvedic science and analytical parameters such as scanning electron microscopy, energy dispersive X-ray analysis, Fourier transform infrared spectrometry and inductively coupled plasma spectrometry were adopted to analyze the final product.Results and Conclusions:Data suggests that vaikrānta bhasma is a multi-mineral compound, which contains iron and silica as major constituents and others are present as trace elements. The data obtained in this study suggest that quality specifications for vaikrānta bhasma can be developed using tests described in Ayurvedic science along with analytical tools available today.

In the field of nanotechnology, developing an environmentally friendly method for the synthesis of iron nanoparticles (FeNPs) an important aspect. The use of secondary metabolites from plant leaf extract has recently emerged as a novel technology for the synthesis of various nanoparticles, according to recent studies. The leaf extract of Azadirachta indica was used to synthesize iron nanoparticles in this research. The effects of reactant concentrations, reaction temperature and pH of the solution on the synthesis process of iron nanoparticles were studied. The formation of iron nanoparticles in dispersion was monitored using a UV-Visible Spectrophotometer that analyzed absorbance spectra. Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) characterized the morphology of iron nanoparticles and results reveal the particles are spherical in shape with an average size of 48 nm. The following are the ideal conditions for synthesis: leaf extract 15%, [FeCl 3 ] = 1.0 mM, pH 6.0 and temperature 60◦C. The plant biomolecules induce the reduction of Fe 3+ ions to FeNPs and act as a capping and stabilizing agent, which is confirmed by the FTIR technique. Therefore, they have good stability for various applications.
