Instrumental neutron activation analysis of Emblica officinalis, Terminalia belerica and Terminalia chebula for trace element efficacy and safety

摘要

To assess the efficacy and safety, essential (Cl, Co, Cr, Fe, K, Mn, Na, Se, Zn), toxic (As, Br, Hg, Sb,) and other elements (Ba, Ce, Cs, Eu, Rb, Sc) were determined in Emblica officinalis (EO), Terminalia belerica (TB) and Terminalia chebula (TC) using instrumental neutron activation analysis. These herbs contain K as a major element, while Co, Cr and Na in EO, Fe, K and Mn in TB and Cl and Zn in TC are the highest.
