Five bark powder samples of Arjuna (Terminalia arjuna) having different origins including two commercial brands were analyzed for 8 minor (Al, Na, K, Mg, Ca, P, Cl, Fe) and 19 trace (As, Ba, Br, Co, Cr, Cs, Cu, Eu, Hg, La, Mn, Rb, Sb, Sc, Sm, Sr, Th, V, Zn) elements by INAA. Also concentrations of Ni, Cd and Pb were determined by AAS and of Sn by ICP-MS. Arjuna bark powder is enriched in Ca (34.1 +/- 10.6 mg/g), Mg (5.41 +/- 1.93 mg/g), K (5.87 +/- 2.18 mg/g), Cl (4.0 +/- 2.2 mg/g) and Fe (2.99 +/- 1.77 mg/g) with significant amounts of Cr (6.9 +/- 4.0 mu g/g), Mn (75.5 +/- 24.8 mu g/g), Sr (114 +/- 69 mu g/g) and Zn (11.9 +/- 8.9 mu g/g). Several toxic elements such as As (78.6 +/- 19.9 ng/g), Cd (5.60 +/- 9.04 mu g/g), Hg (69 +/- 41 ng/g) and Pb (5.0 +/- 3.5 mu g/g) were also detected.
