## Abstract Four new triterpenoid saponins, named scheffarboside A – D (**1**–**4**), along with five known saponins were isolated from the stems of __Schefflera arboricola.__ The structures of the four new saponins were determined as 3‐__O__‐(__O‐β__‐glucuronopyranosyl‐(1 → 3)‐__O‐α__‐rhamnopyrano
Two new bisdesmosidic triterpenoid saponins, i.e. 1 and 2, were isolated, besides the three known saponins 3 ± 5, from the MeOH extract of the aerial parts of Achyranthes aspera Linn. (Amaranthaceae). Their structures were elucidated as 2) by NMR spectroscopy, including 2D-NMR experiments (machaeri
