摘要：

Three new furostanol saponins, tuberoside A, B and C, have been isolated from the seeds of Allium tuberosum. On the basis of chemical reactions and spectral data, their structures were established as 26-O-beta-D-glucopyranosyl-(25 S)-5 alpha-furost-20(22)-ene-2 alpha,3 beta,26-triol 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-O-beta-D-glucopyranoside; 26-O-beta-D-glucopyranosyl-(25 S)-5 alpha-furost-20(22)-ene-2 alpha,3 beta,26-triol 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-[alpha-L-rhamnopyranosyl-(1 --> 4)]-beta-D-glucopyranoside and 26-O-beta-D-glucopyranosyl-(25 S)-5 alpha-furost-20(22)-ene-2 alpha,3 beta,26-triol 3-O-alpha-L-rhamnopyranosyl-(1 --> 2)-[beta-D-glucopyranosyl-(1 -->3)]-beta-D-glucopyranoside, respectively.
