摘要

The linkage between the sugars moieties of antifungal spirostan saponin, (25R)-5α-spirost-7-en-2α,3β,5α-triol-3-O-{-O-α-L-rhamnopyranosyl-(1→2)-O-[β-D-galactopyranosyl-(1→3)]-β-D-glucopyranoside} of Agapanthus africanus (Linn.) have been determined by the analysis of GC-MS spectra of alditol acetates of the partially methylated sugars and the structures of the spirostan saponin and furostan saponin, 22-O-methyl-26-O-β-D-glucopyranosyl-(25R)-5α-furostan-2α,3p,5α,9α,22ζ,26-hexitol-3-O-{-O-α-L-rhamnopyranosyl-(1→2)-O-[β-D-galactopyranosyl-(1→3)]-β-D-glucopyranoside} isolated from the rhizomes of the A. africanus have been established by various spectral evidences. This is the first report of furostan saponin in A. africanus rhizomes as well as first account of the use of GC-MS technique to ascertain the linkage between the saccharide moieties of the active constituent of the plant.
