The Steroidal Glycosides of Allium waldsteini G. Don

Abstract

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-1β,3β-diol 1-0-[α-Lrhamnopyranosyl.(1→2)-α-L-arabinopyranoside], (25R)-spirost-5-ene-1β,3β-diol 1-0-[β-D-glucopyranosyl.(1→3)-α-Lrhamnopyranosyl.(1→2)-α-L-arabinopyranoside] and 26-0-β-D-glucopyranosyl-(22R,25R).furost-5-ene-1β,3β,22α,26-tetrol 1-0-[α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside].
