Eight triterpenoid saponins (1–8) have been isolated from the berries of Lonicera nigral. (Caprifoliaceae) by combination of droplet counter-current chromatography and column chromatography on silica. The structures have been established by 1H-NMR., 13C-NMR. spectroscopy, FD.-MS., FAB.-MS. and D./CI.-MS., and on the basis of acidic and basic hydrolyses. The monodesmosidic saponins 1–5 possess strong molluscicidal activity against the schistosomiasis-transmitting snail Biomphalaria glabrata, whereas the bidesmosidic saponins 6–8 are inactive.
