Chemical investigation of the roots of Glycyrrhiza uralensis resulted in the isolation of six oleanane-type triterpene glycosides (1 – 6), including one new saponin (1) and two (2 and 3) obtained as natural products for the first time. The new licorice saponin (1) was identified as 22β–acetoxylglycyrrhizin from [α] D , mass spectrometric, and UV, IR, and NMR spectroscopic data.. Full assignments of  1 H and  13 C-NMR data for compounds 2, 3, 4, 5 and 6 were made for the first time according to 2D NMR methods.
