title: Molluscicidal triterpenoidal saponin from Lysimachia sikokiana.
abstract: The main molluscicidal activity of the methanol extract of Lysimachia sikokiana is due to several triterpenic saponins called sakuraso-saponins. The most active component was isolated from the aerial parts and elucidated as 3-O-beta-xylopyranosyl-(1----2)-beta-glucopyranosyl-(1----4)- [beta-glucopyranosyl-(1----2)]-alpha-arabinopyranosyl protoprimulagenin A, named lysikoianoside 1, on the basis of 1H- and 13C-nuclear magnetic resonance spectral data and methylation analysis results.
