Study on the Content of Beneficial Elements, Harmful Elements and Rare Earth Elements in the Wild Soybean (Glycine soja) by ICP-MS

摘要

Wild soybean originated in China, but trace element nutrition in wild China Ixeris has not been reported. The results showed that wild soybean contained much macroelements Mg, P, K, Ca and Mn, but the concentrations Mg, P, K and Ca are much lower than those in cultured soybean, while the concentrations of Mn and Fe have no significant difference. Beneficial trace elements Se, Co and Mo in wild soybean are significantly higher than that in cultured soybean. The wild soybean contained much Al, Cu and Ni, but all heavy metals did not exceed the national standards. Rare earth elements in wild soybean were at a very low level, most of rare earth elements were below 1 ng/g and six kind of rare earth elements are not detected (Tb, Dy, Er, Tm, Yb and Lu).
