Studies on the Structures and Molluscicidal Activity of Saponins from Smilax Glauco-China Warb
Chen Yan Wu Dongru Li Guoxian (Department of Biology)
Two steroidal saponins named Heiguobaqia saponin A and Heiguobaqia saponin B were isolated from the methanol extract of rhizome of Smilax glauco-china Warb (Liliaceae) by chromatographic method.On the basis of acetylation acid hydrolysis、Infrared Spectrum、Mass Spectrum and some physical contants etc.The chemical structure of Saponin A has been elucidated and identified as sarsasapogenin-3-0[β-D-glucopyranosyl(1→?)] -[α-L-rhamnopyranosyl (1→?)]-β-D-glucopyranoside.Heiguobaqia Saponins weretestcd for molluscicidal activity.The crude,saponins ane Saponin A were shown to have strong killing activity.
