The steroidal glycosides of Allium waldsteini G. Don

Three steroidal compounds were isolated from the air-dried, pulverized, over ground parts of Allium waldsteini G. Don, and, on the basis of physical and chemical investigations, their structures were elucidated as (25R)-spirost-5-ene-1 beta,3 beta-diol 1-O-[alpha-L-rhamnopyranosyl-(1 -> 2)-(X-L-arabinopyranoside], (25R)-spirost-5-ene-1 beta,3 beta-diol 1-O-[beta-D-glucopyranosyl-(1 beta 3)-(alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranoside] and 26-O-beta-D-glucopyranosyl-(22R, 25R)-furost-5-ene-1 beta,3 beta,22 alpha,26-tetrol 1-O-[alpha-L-rhamnopyranosyl-(1 -> 2)-alpha-L-arabinopyranoside].
