Investigation of characteristic constituents of the roots of Glycyrrhiza uralensis Fischer led to isolation of four new triterpene glucuronides, namely uralsaponins C–F (1–4), an artificial product, namely the methyl ester of glycyrrhizin (5), as well as six known triterpene glucuronides (6–11). These new compounds were identified by 1D and 2D NMR spectroscopic analysis. The cytotoxicity of the selected compounds and their aglycones were evaluated against HeLa and MCF-7 cancer cell lines, and the preliminary structure-activity relationship was also elucidated.
