## Abstract Four new triterpenoid saponins, named scheffarboside A β D (**1**β**4**), along with five known saponins were isolated from the stems of __Schefflera arboricola.__ The structures of the four new saponins were determined as 3β__O__β(__OβΞ²__βglucuronopyranosylβ(1β ββ 3)β__OβΞ±__βrhamnopyrano
Two new bisdesmosidic triterpenoid saponins, i.e. 1 and 2, were isolated, besides the three known saponins 3 Β± 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
