[Objective] The aim was to analyze the primary speciation of 6 microelements in Glycyrrhiza uralensis Fisch. and provide theoretical basis for explaining pharmacodynamic principle of liquorice and discussing quality control of liquorice planting. [Method] The six elements, Cu, Zn, Ca, Fe, Mg, Mn in roots of G. uralensis Fisch. were extracted based on traditional analytical flowchart program and were separated into water-soluble state and suspension state by micro porous filtering film. The elements in water-soluble state were detected by flame atomic adsorption spectrophotometry (FAAS). [Result] The results showed that extractive rates of the elements were in the range of 1.71%-60.06%, and immerse-residue ratio in 0.018 3-1.682; the results also indicated that the immerse-residue ratio of Zn was biggest (1.68), Zn played an important medical role and might be considered as the best characteristic element in G. uralensis Fisch.; the recoveries of the elements were ranged from 95.72%-103.15% and relative standard deviations (RSD) were less than 2.38%. [Conclusion] Because of its high accuracy, FAAS method is feasible for analyzing primary speciation of microelements in G. uralensis Fisch..
