Description:
Two new hederagenin-type saponins, staunoside G ( 1 ) and staunoside H ( 2 ), along with twelve known triterpenoid saponins, were isolated from stems of Stauntonia obovatifoliola Hayata ssp. intermedia. Their structures were determined by analysis of HR-EI-MS, and 1D- and 2D-NMR data, and comparison with those in literature. The two new compounds showed moderate cytotoxicities against three tumor cells, i.e. , A549 (lung carcinoma), 4T1 (mammary carcinoma), and HeLa (cervical carcinoma).
