An antifungal saponin was isolated from the bottom cut of white asparagus ( Asparagus officinalis L), which is unusable in food processing. The structure of the saponin was identified as 3‐ O ‐[{α‐ L ‐rhamnopyranosyl (1→2)} {α‐ L ‐rhamnopyranosyl (1→4)}‐β‐ D ‐glucopyranosyl] (25 S ) spirost‐5‐ene‐3β‐ol from chemical and spectral data. This saponin was shown to be identical with collettinside III from Dioscorea collettii , and to inhibit the growth of some kinds of fungi at μg ml −1 levels.
