摘要：
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 (3 beta,5a,6 beta,25R)-3-{(O-beta-D-glucopyranosyl-(1?3)-beta-D-glucopyranosyl-(1?2)-O-[O-beta-D-glucopyranosyl-(1?3)]-O-beta-D-glucopyranosyl-(1?4)-beta-D-galactopyranosyl)oxy}-6-hydroxyspirostan-2-one (1). Results of the present study indicated that 1 exhibited haemolytic activity in the in vitro assays, and immunological adjuvant activity on the cellular immune response against ovalbumin antigen.
