Ardisikivuoside, a new triterpenoid saponin from Ardisia kivuensis (Myrsinaceae)

摘要

Column chromatography of the n-butanol extract of the stem of Ardisia kivuensis (Myrsinaceae) led to the isolation of a new triterpenoid saponin, ardisikivuoside (1) {3-O-β-D-xylopyranosyl-(1→3)-β-D- glucopyranosyl-(1rarr;4)-β-D-xylopyranosyl-3β-hydroxy-13β, 28-epoxyoleanan-16-oxo-30-al}. The structure was elucidated on the basis of spectral studies.
