【 摘 要 】

A new molluscicidal triterpenoid saponin, napoleonaside [1] has been isolated from themethanolic extract of the fruit of Napoleonaea imperialis . The structure of napoleonaside was established as 3β-O-[{β-D-glucopyranosyl(1→4)}{α-L-arabinopyranosyl(1→2)- β-D-glucopyranosyl(1→2)}- β-Dglucuronopyranosyl]-16α,22α,24,28-tetrahydroxyl-21- β-O-angeloxyolean-12-ene, by spectroscopic (IR,FABMS, 1H and 13C-NMR) methods. Napoleonaside was tested for its molluscicidal properties against Biomphalaria glabrataand was found to be one of the most potent naturally occurring plant molluscicides withactivity of 0.4ppm (observed after 24hrs).
