Abstract：
:Thirteen steroidal saponins were isolated from the leaves of Beaucarnea recurvata Lem. Their structures were established using one- and two-dimensional NMR spectroscopy and mass spectrometry. Six of them were identified as: 26-O-β-D-glucopyranosyl (25S)-furosta-5,20(22)-diene 1β,3β,26-triol 1-O-α-L-rhamnopyranosyl-(1→2) β-D-fucopyranoside, 26-O-β-D-glucopyranosyl (25S)-furosta-5,20(22)-diene 1β,3β,26-triol 1-O-α-L-rhamnopyranosyl-(1→2)-4-O-acetyl-β-D-fucopyranoside, 26-O-β-D-glucopyranosyl (25R)-furosta-5,20(22)-diene-23-one-1β,3β,26-triol 1-O-α-L-rhamnopyranosyl-(1→2) β-D-fucopyranoside, 26-O-β-D-glucopyranosyl (25S)-furosta-5-ene-1β,3β,22α,26-tetrol 1-O-α-L-rhamnopyranosyl-(1→4)-6-O-acetyl-β-D-glucopyranoside, 26-O-β-D-glucopyranosyl (25S)-furosta-5-ene-1β,3β,22α,26-tetrol 1-O-α-L-rhamnopyranosyl-(1→2) β-D-fucopyranoside, and 24-O-β-D-glucopyranosyl (25R)-spirost-5-ene-1β,3β,24-triol 1-O-α-L-rhamnopyranosyl-(1→2)-4-O-acetyl-β-D-fucopyranoside. The chemotaxonomic classification of B. recurvata in the family Ruscaceae was discussed.
