英文摘要Four new steroidal saponins, 26-O-beta -D-glucopyranosyl-(25S,20R)-20-O-methyl-5 alpha -furost-22(23)-en-2 alpha ,3 beta ,20,26-tetraol 3-O-alpha -L-rhamnopyranosyl-(1 -->2)-[alpha -L-rhamnopyranosyl-(1 -->4)]-beta -D-glucopyranoside (1); 26-O-beta -D-glucopyranosyl-(25S,20R)-5 alpha -furost-22(23)-en-2 alpha ,3 beta ,20,26-tetraol 3-O-alpha -L-rhamnopyranosyl-(1 -->2)- [alpha -L-rhamnopyranosyl-(1 -->4)]-beta -D-glucopyranoside (2); 26-O-beta -D-glucopyranosyl-(25S,20S)-5 alpha -furost-22(23)-en-2 alpha ,3 beta ,20,26-tetraol 3-O-alpha -L-rhamnopyranosyl,(1 -->2)-[alpha -L-rhamnopyranosyl-(1 -->4)]-beta -D-glucopyranoside (3); and 26-O-beta -D-glucopyranosyl-(25S,20S)-5 alpha -furost-22(23)-en-3 beta ,20,26-triol 3-O-a-L-rhamnopyranosyl-(1 -->2)-[alpha -L-rhamnopyranosyl-(1 -->4)]-beta -D-glucopyranoside (4), have been isolated from the seeds of Allium tuberosum. Their structures were established by spectroscopic studies such as MS, IR, NMR, and BD-NMR and the results of acid hydrolysis and named tuberosides F, G, H, and I, respectively.
