Application of Spectroscopic and Chromatographic Methods for Chemical Characterization of an Ayurvedic Herbo-Mineral Preparation: Maha Yograja Guggulu.

Abstract

Rasa Shastra is an exclusive branch of ayurveda that uses processed metals and minerals in various combinations. Though the formulations are time tested, safety and quality concerns are being raised since the past two decades. In view of this, it becomes mandatory to generate quality control profiles of such formulations by following available parameters. Considering this, we attempted to develop standard manufacturing procedures of Maha Yogaraja Guggulu and generate preliminary physicochemical profiles using inductively coupled plasma mass spectrometry, X-ray diffraction, and high-performance thin-layer chromatography. The results from high-performance thin-layer chromatography revealed presence of organic constituents from plant material. X-ray diffraction indicated that the prepared drug contained cinnabar (mercury sulfide; Rasa sindhura), cassiterite (tin oxide; Vanga bhasma), litharge (lead oxide; Naga bhasma), and iron dioxide and magnetite (di-iron oxide; Loha and Mandura bhasma). The observations of the present study are preliminary and first of its kind that may be considered as baseline data for future studies.
