The cation contents in imported licorice roots, i.e. 6 samples from Xibei (西北産), 4 samples from Xinjiang (新彊産), 1 sample from Turkmenistan and 1 sample from Afghanistan were determinated by Ion chromatography. All the licorice roots contained K+, Na+, Mg^<2+>, NH_4^+ and Ca^<2+>, however, Xibei licorice samples generally contained more NH_4^+, Mg^<2+> and Ca^<2+>, and less Na^+ and K^+ than the others. Furthermore, the changes of cation contents during the refining process of Glycyrrhizin were investigated. The Na^+, Mg^<2+> and Ca^<2+> contents decreased greatly during the crystarization process of Glycyrrhizin, though the K^+ and NH_4^+ contents remained unchanged in Glycyrrhizin.
