Abstract：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.
Key words：Cistanche deserticola Y.C.Ma;ICP-MS;Rare earth elements
