Abstract
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 spectro scopic techniques and the result of acid hydrolysis. The saponin is unique in structure having a diglycoside unit at C-23 of the spirostanol skeleton. (C) 1999 Elsevier Science Ltd. All rights reserved.
