Glycyrrhiza uralensis and various licorice roots imported from Dongbei (東北) Xibei (西北), Xinjiang (新疆), Pakistan, the Soviet Union and Afghanistan were analyzed by HPLC with reference to glycyrrhizin (1) and 10 flavonoids-apioliquiritin (2), liquiritin (3), apioisoliquiritin (4), isoliquiritin (5), ononin (6), liquiritigenin (7), glycycoumarin (8), glycyrol (9), isoglycyrol (10) and glycyrin (11). Principal Component Analysis (PCA) was performed on the basis of their 1-10 contents: licorice roots of the Soviet Union, Afghanistan, Pakistan and Xinjiang resembled each other and were generally lower in the 3 content than those from Dongbei and Xibei contained less 3 than the latter. The 3 content of some Pakistani licorice root was found to be quite low. In Dongbei and Xibei licorice roots, both 8-11 contents and 1-7 contents varied so much that there could be found no significant difference. PCA applied to the data of 1-10 and 8-11 indicated that Dongbei roots in general contained more 1, 3, 8 and 9 and less 11.
