A New Oleanane-Type Triterpene Glycoside from Glycyrrhiza uralensis

In order to investigate the chemical constituents of the roots of Glycyrrhiza uralensis Fisch, the constituents were isolated by using preparative HPLC. The structures of the isolated compounds were identified by spectral evidence. A new oleanane-type triterpenoid saponin (S3) and 11 known compounds were obtained. The new licorice saponin (S3) was identified as 22β-acetoxyl-glycyrrhaldehyde based on MS, UV, IR and NMR spectroscopic data.
