  Two new spirostanol saponins, tuberosides D and E, have been isolated from the seeds of Allium tuberosum. On the basis of spectral data and chemical reactions, their structures were established as (25S)-5α-spirostane-2α,3β-diol 3-O-α-L-rhamnopyranosyl-(1→2)-O-[α-L-rhamnopyranosyl-(1→4)]-O-β-D-glucopyranoside and (25S)-5α-spirostan-2α,3β-diol 3-O-β-D-glucopyranosyl-(1→2)-O-[α-L-rhamnopyranosyl-(1→4)]-O-β-D-glucopyranoside, respectively.
