title: Saponins from three species of Mimusops.
abstract: Six saponins were isolated from the seed kernel of Mimusops elengi, M. hexandra and M. manilkara. Their structures were determined using a combination of 1H NMR, 13C NMR and mass spectroscopy. Three of them are new compounds: 3-O-(beta-D-glucuronopyranosyl) 28-O-(alpha-L-rhamnopyranosyl (1-->3) beta-D-xylopyranosyl(1-->4) [alpha-L-rhamnopyranosyl(1-->3)] alpha-L-rhamnopyranosyl(1-->2) alpha-L-arabinopyranosyl) protobassic acid, 3-O-(beta-D-glucuronopyranosly) 28-O-(alpha-L-rhamnopyranosyl(1-->3) beta-D-xylopyranosyl(1-->4) alpha-L-rhamnopyranosyl(1-->2) alpha-L-arabinopyranosyl) 16-alpha-hydroxyprotobassic acid and 3-O-(beta-D-glucopyranosyl(1-->3) beta-D-glucopyranosyl) 28-O-(alpha-L-rhamnopyranosyl(1-->3) beta-D-xylopyranosyl(1-->4) alpha-L-rhamnopyranosyl(1-->2) alpha-L-arabinopyranosyl) protobassic acid.
