QUANTITATIVE ANALYSIS OF THE CONTENT OF MICRO- AND MACRO ELEMENTS IN THE AMARANTH LEAF EXTRACT

The study of the amaranth plant Amaranthus cruentus L. was carried out on ICP-MS with the
optics of an emission spectrometer with inductively coupled argon plasma. It has been established
that the content of heavy metals and toxic elements in food products, for example, lead (Pb) 5.0
mg/kg, arsenic (As) – 3.0 mg/kg, cadmium (Cd) 1.0 mg/kg, i.e. e. do not exceed the maximum
permissible level. The influence of the concentration of water-alcohol solutions on the optical
density of the extract was also studied.
