THE ELEMENTAL COMPOSITION OF WILD LOTUS CORNICULATUS AND CULTIVATED IN THE SUBTAIGA ZONE OF WESTERN SIBERIA

The composition and content of the elements of the aerial parts of the Lotus corniculatus L. wild-growing and cultivated in the Tomsk region was studied. The elemental composition was studied by neutron activation analysis and flame photometry. The neutron activation method was studied on a CANBERRA analyzer system with a pure germanium detector of the GX-3518 type with Co60 (1332 keV) 1.8 keV placement (neutron flux density 2·1013 neutrons/(cm2·s) for 12 h) . The sodium and potassium contents were determined in the emission mode by flame photometry on a Thermo Solaar M5 Mkll double-beam atomic absorption spectrometer. In wild-growing and cultivated species, the content of 31 elements (Sm, Ce, Ca, Lu, U, Th, Cr, Yb, Au, Hf, Ba, Sr, Nd, As, Ag, Br, Cs, Tb, Sc, Rb, Fe, Zn, Ta, Co, Na, K, Eu, Sb, La, Pb, Cd). In wild-growing and cultivated samples from the Tomsk region, high concentrations of Ca, K, Na, and Zn are noted, compared with the data given in the literature on lamb from other regions. According to the content of heavy metals, wild-growing and cultivated in the Tomsk Oblast baby candy meets the requirements of regulatory documents and can be used for the production of dietary supplements, herbal medicines and herbal pharmaceutical substances. In terms of Zn content, wild-growing and cultivated lamb does not meet the requirements for the minimum allowable levels of this element for feed, which manufacturers should take into account.
