INVESTIGATION OF INORGANIC CONTENTS OF SOME DIURETIC PHARMACEUTICAL HERBS GROWING IN TURKEY BY THE X-RAY-FLUORESCENCE EMISSION-TRANSMISSION(E-T) TECHNIQUE

A radioisotope excited X-ray fluorescence Emission - Transmission (E - T) technique was applied for the determination of inorganic contents o f some diuretic pharmaceutical herbs growing in Turkey. Folia Betulae, Stylus Maydis, Flores Verbasci, Equisetum Arvense and Flos Helichrysi herbs which are widely used by public at the cure of kidney diseases were investigated. The study was based on advantages of the XRF E - T method by means of the neglectable enhancement effect and analysis wit hout reference material. An annular source of Cd-109 (3.7 MBq) was emp loyed for excitation of characteristic K X-rays of the elements in the herbs. Herb samples were prepared in dry and wet forms for the method . The leaching ratios of the elements in these herbs in the period of steeping were calculated. Toxic elements in the considerable amount we re not found. It was observed that the other element contents in the d ry and wet forms are different.
