Two new saponins, notoginsenosides Ng1 (
1 ) and Ng2 (2 ), together with seven known compounds (3-9 ), were isolated from the leaves ofPanax notoginseng . Their structures were elucidated by UV, IR, HRESIMS, and NMR experiments. Compounds6 and7 showed moderate cytotoxic activities against HCT-116, with IC50 values of 4.98 and 0.64 μmol/L, respectively. [ABSTRACT FROM AUTHOR]- Published
