Abstract (AB)	Four triterpenoid saponins isolated from the leaves of Polyscias dichroostachya were identified as 3-O-[_-L-arabinopyranosyl]-hederagenin, 3-O-[_-L-rhamnopyranosyl-(1 - 2)-_-L-arabinopyranosyl]-hederagenin, 3-O-[ß-D-glucopyranosyl-(1 - 2)-_-L-arabinopyranosyl]-hederagenin, 3-O-[_-L-rhamnopyranosyl-(1 - 2)-_-L-arabinopyranosyl]-hederagenin 28-O-ß-D-glucopyranoside. The three monodesmosidic saponins were found to possess strong molluscicidal activity against the schistosomiasis-transmitting snails Biomphalaria glabrata, whereas the bidesmosidic saponin, a new natural product, was inactive.
