Haemolytic activity and immunological adjuvant effect of a new steroidal saponin from Allium ampeloprasum var. porrum.

Abstract

A new steroidal saponin was isolated from the bulbs of Allium ampeloprasum L. var. porrum. On the basis of chemical evidence, comprehensive spectroscopic analyses, and comparison with known compounds, its structure was established as (3β,5α,6β,25R)-3-{(O-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→2)-O-[O-β-D-glucopyranosyl-(1→3)]-O-β-D-glucopyranosyl-(1… (More)
