A spirostanol saponin from the underground parts of Ruscus aculeatus.
A new spirostanol saponin was isolated from the underground parts of Ruscus aculeatus and the structure was assigned as (23S,25R)-spirost-5-ene-3 beta,23-diol 23-O-[O-beta-D-glucopyranosyl-(1-->6)-beta-D-glucopyranoside] on the basis of spectroscopic analysis, including two-dimensional NMR spectroscopic techniques and the result of acid hydrolysis. The saponin is unique in structure having a diglycoside unit at C-23 of the spirostanol skeleton.
