Quantitative Determination of Essential and Trace Element Content of Some Medicinal Plants by ICP-MS Technique

Micro-and macroelements contents of five traditionally used medicinal plants (Withania somnifera, Hemidesmus indicus, Cyathula prostrate, Andropogan zizanioides and Momordica charantia) were quantitatively evaluated by the inductively coupled plasma mass spectrometry (ICP-MS) technique. The analytical investigation allows totally 20 elements (Li, Be, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Ag, Cs, Ba and Tl) from these plant extracts. The ICP-MS techniques are well suited for the analytical control of infusions in order to ascertain the nutritional role of medicinal plants and the daily dietary intake. The results of present investigation used to set new standards for prescribing the dosage of the herbal drugs.
