Glycyrrhiza uralensis which is the original plant of Dongbei licorice (東北甘草), was obtained in Neimenggu (内蒙古) and Jilin (吉林省), and analyzed by HPLC for the glycyrrhizin (1) and 6 flavonoid contents apioliquiritin (2), liquiritin (3), apioisoliquiritin (4), isoliquiritin (5), ononin (6), liquiritigenin (7). The quantities of these compounds in licorice from various regions of China [Dongbei licorice, Xibei ones (西北甘草) and Xinjiang (新彊甘草)] were compared by the principal component analysis (PCA). 1. 1〜7 were not detected in the aerial part of G. uralensis. 2. The amounts of 1〜7 contained in licorice root varied considerably and their contents were not related to the commercial grade of the crude drug. The analytical data of Dongbei licorice were similar to those of Xibei licorice, though the amounts of both 1 and 3 were higher in Dongbei licorice than in Xibei licorice. 3. Licorice from Xinjiang (新彊) generally contained a smaller amount of 3 than those from Dongbei and Xibei, and this difference was clearly shown by PCA analysis.
