Abstract: Energy Dispersive X-ray Fluorescence (ED-XRF) spectroscopy and Inductively Coupled Plasma Mass Spectroscopy (ICPMS) are used for qualitative and quantitative determination of major, minor and trace elements in some herbs which are used widely in many Ayurvedic medicines. Concentrations of major elements like Mg, K, Al, Ca, Cl, Fe, Mn, S, P and trace elements like Mn, Cu, Zn, Sr, Rb are determined by XRF while that of Ti, V, Cr, Co, Ni, Cu, Zn, Br, Cd, Hg, Zr are done using ICPMS. Elements which show the same concentration in both of the methods are identified. Combining these two analyses, a comprehensive elemental fingerprint of the samples is produced. The result will serve as a data bank for fingerprinting of herbals and herbal products to ensure quality and authenticity.
