Investigation of Inorganic Contents of Some Diuretic Pharmaceutical Herbs Growing in Turkey by the X - Ray Fluorescence Emission - Transmission (E - T) Technique

Abstract

A radioisotope excited X-ray fluorescence Emission - Transmission (E -T) technique was applied for the determination of inorganic contents of 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 without reference material. An annular source of Cd-109 (3.7 MBq) was employed 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 were not found. It was observed that the other element contents in the dry and wet forms are different.
