Elemental Composition of the Astragalus Ferganensis Plant Growing in the Fergana Valley
Abstract
The elemental composition of the root and aboveground parts of the plant Astragalus ferganensis growing in the Fergana Valley of Uzbekistan was studied using the ICP-OES method. The 30 identified elements were analyzed by classifying them into groups of macro-, micro-, essential, and heavy metals. Among the elements detected in the plant organs, the amounts of Ca, K, Mg, Na, P were relatively high (over 1000 mg/kg), Fe, Si, S were high (50-1000 mg/kg), Mn, Zn, B, Cu were moderate (10-100 mg/kg), Cr, V, Li were low (1-10 mg/kg), Ba, Ni, Pb, Se, As, Co were very low (1-5 mg/kg), while Ag, Bi, Cd, Hg, Sb were not detected. In the underground and aboveground parts of the plants, the predominance of macroelements Ca, K, Mg and microelements Fe, Si was determined.
