Compositional Analysis of Ayurvedic Medicine Using Libs Along With Pas Techniques

Abstract

In the present work, elemental and molecular compositions of Ayurvedic medicine have been performed using Photoacoustic Spectroscopy (PAS) and Laser-Induced Breakdown Spectroscopy (LIBS) techniques. The molecular bands of Protein, Carbohydrate, Flavonoid, and Chlorophyll, etc., have been observed using the PAS technique. PAS is based on the detection of photon-induced acoustic (PA) signals generated via non-radiative transition processes. The spectral lines of organic elements (C, H, N, and O) as well as the spectral lines of minerals (Al, Ca, Fe, Mg, Na, Si, and Sr) have been observed in the Laser-induced Breakdown (LIB) spectrum of the medicine. The presence of the spectral lines of organic elements is due to the photo fragments of the organic compounds present in the medicine. The molecular band of CN molecule in the LIB spectrum of the medicine further confirms the medicines' organic compound. Thus, along with LIBS, PAS is a suitable technique for the complete compositional analysis of Ayurvedic medication.
