title: Ardisikivuoside, a new triterpenoid saponin from Ardisia kivuensis (Myrsinaceae).
abstract: 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-beta-D-xylopyranosyl-(1 --> 3)-beta-D-glucopyranosyl-(1 --> 4)-beta-D-xylopyranosyl-3beta-hydroxy-13beta,28-epoxyoleanan-16-oxo-30-al}. The structure was elucidated on the basis of spectral studies.
