Two new saponins, notoginsenosides Ng1 (1) and Ng2 (2), together with seven known compounds (3-9), were isolated from the leaves of Panax notoginseng. Their structures were elucidated by UV, IR, HRESIMS, and NMR experiments. Compounds 6 and 7 showed moderate cytotoxic activities against HCT-116, with IC values of 4.98 and 0.64 μmol/L, respectively.
