[Application of ICP-MS to detect rare elements in wild Cistanche deserticola Y. C. Ma].

Rare metals are important nutritional elements for human health.Fifteen rare metals in wild Cistanche deserticola Y.C.Ma were analyzed by the methods of ICP-MS.The results showed that concentrations of La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Yb and Lu in Wild Cistanche deserticola Y.C.Ma were 144.89,259.75,36.41,133.25,25.38,6.10,30.20,3.85,20.36,3.42,8.55,6.42,1.15,20.02 and 29.77 ng·g-1 respectively,the character of elements and the content of rare earth elements in soil should be responsible for the difference,but the mechanism of distribution should be further studied.
