Determination of essential and non-essential elements in some medicinal plants by polarised X ray fluorescence spectrometer (EDPXRF)

Polarised X ray fluorescence spectrometer (EDPXRF) is employed for the determination of essential and non-essential elements in the parts (leaves, fruits, seeds, roots, flowers, barks, berries, and thallus) of thirty-five medicinal plants used in Italy generally as remedies. The quality of data was assured by calibrating the instrument with certified reference materials. The elements are found to be present in different plants in various proportions depending on soil composition and the climate in which the plant grows.
