The stem and seeds of Withania somnifera were digested with HNO₃ and HClO₄ (4:1) and the contents of thirteen trace elements such as Zn, Fe,Ni, Mn ,K ,Ca, Mg, Co, Cr, Cu, Cd, Pb, and As from different parts were determined by atomic absorption spectroscopy. The experimental results confirmed the presence of Fe, Ca, Mg, Zn, Ni, Co and Mn which are beneficial to the human body is within the limit and K is not detected. The heavy trace element which are harmful to human body i.e., Cd, Pb, Cu within the limit but As is higher and Cr is not detected.
