A. Bassari et al., DETERMINATION OF MAJOR AND MINOR ELEMENTS IN NATURAL DRUGS USING X-RAY-FLUORESCENCE ANALYSIS, Journal of environmental science and health. Part A: Environmental science and engineering, 32(6), 1997, pp. 1677-1685
For many years the role and metabolic functions of trace elements have
intensively been investigated. Natural drugs are widely used for diur
etic, phlegm elimination and stomach invigoration purposes. Twenty-nin
e of natural drugs used by Turkish people have been subjected to trace
element analysis by radioisotope excited energy dispersive x-ray fluo
rescence analysis. Within this large number of different natural produ
cts, seventeen elements were detected.
