| Abstract: | Three new triterpenoid saponins, impatiprins A-C (1-3), together with a known triterpenoid (4) and two known triterpenoid saponins (5, 6), were isolated from the rhizomes of Impatiens pritzellii Hook. f. var. hupehensis Hook. f. The structures of 1-3 were determined by 1D and 2D NMR, FAB-MS techniques and chemical methods. Compounds 1 and 2 showed weak cytotoxicities against S-180, HeLa and HepG2 cell lines. |
