Multielement determination in fruit, soaps, and gummy extract of Pistacia terebinthus L. by ICP OES

Multielement analyses were carried out on whole fruit, soaps, gummy extract, and fresh infusions of Pistacia terebinthus using the ICP OES technique. Digestion processes were optimized in a microwave oven. Qualitatively, the elements Al, As, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ge, Hg, In, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Pd, Sb, Sc, Se, Si, Sn, Sr, Te, Ti, V, W, and Zn were found in the fresh fruit. Al, Cd, and Pb levels in the infusions of gummy extract exceeded the upper limits specified by the Turkish Food Codex and filtration was recommended before consumption of the hot beverage. Using ICP OES a determination of metals was checked with standard reference material (GBW 07605).
