Analysis of Macroelements, Beneficial Trace Elements, Rare Earth Elements in the Wild Ixeris Chinensis (Thunb.) Nakai by ICP-MS

Abstract

Wild China Ixeris [Ixeris chinensis (Thunb.) Nakai] has Chinese herbal properties and can be used for the treatment for many diseases. But trace element nutrition in wild China Ixeris has not been reported, including heavy metals, beneficial elements for human health and rare earth elements. The results showed that the concentrations of macrolements and beneficial trace elements in wild China Ixeris are many times higher than those in most vegetables, such as radish, cucumber, garland chrysanthemum, parsley, chives and leek moss, so wild China Ixeris is of great significance to complement macrolements and beneficial trace elements for the human health. Rare earth elements in wild China Ixeris are at a low level. Some heavy metals in wild China Ixeris exceeded the national standard, so before eating the harmful elements in wild China Ixeris should be detected.
