Spectroscopic evidence is presented for the structures of four new triterpenoid saponins 3-O-beta-D-glucuronopyranosylsejanic acid, 3-O-beta-D-glucuronopyrancsylphytolaccageni acid 3-O-beta-D-glucuronopyranosyl-28-O-beta-D-glucopyranosylserjanic acid and 3-O-beta-D-glucuronopyranosyl-28-O-beta-D-glucopyranosylphytolaccagenic acid isolated from Diploclisia glaucescens. One saponin has shown acceptable molluscicidal activity.
