Saponins with Molluscicidal Activity from Hedera helixL
摘要:
Four triterpenoid saponins (1–4) have been isolated from the berries of Hedera helix L. (Araliaceae) by droplet counter-current and preparative liquid chromatography. The structures have been established by FD./MS. and 13 C-NMR. spectroscopy. The isolated compounds were found to possess strong molluscicidal activity against the bilharziasis-transmitting snail Biomphalaria glabrata. Saponin 4 , identified as hederagenin 3- O -β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranoside, is a new natural product.
