Abstract：The elemental transference characteristics and primary speciation analysis of Arnebia euthroma (Royle) Johnst were investigated in the present paper. The results showed: sealed digestion at high temperature was more efficient and thorough than microwave-assisted process(MAP) digestion in the preparation of speciation analysis; Most of the elements analyzed, excluding potassium and zinc, exist in particulate speciation in the plant; The transference characteristics of elements were associated with the polarity of extraction solvents. Contents of all 22 elements basically were directly proportional to the polarity of solvents varying from almost no polarity to strong, especially for 7 elements: magnesium, potassium, calcium, manganese, cobalt, thallium and lead.
