Title: Pachyelasides A-D, novel molluscicidal triterpene saponins from Pachyelasma tessmannii.

Authors: Nihei K, Ying BP, Murakami T, Matsuda H, Hashimoto M, Kubo I.

Abstract: This is the first report for secondary metabolites in an African medicinal plant, Pachyelasma tessmannii (Leguminosae). Four novel saponins, pachyelasides A-D, were isolated from the methanol extract of the root bark by using recycling HPLC. These compounds showed molluscicidal activity (LD(50) < or =8.0 mug/mL) against the South American snail, Biomphalaria glabratus. The structures were determined on the basis of extensive nuclear magnetic resonance spectroscopic and matrix-assisted laser desorption/ionization time-of-flight mass spectrometric studies.
