title: Triterpenoid saponins of Mimusops elengi.
abstract: In addition to characterization of taxifolin, alpha-spinasterol glucoside, Mi-glycoside 1, two new triterpenoid saponins mimusopside A and B were isolated from the seeds of Mimusops elengi and were, respectively, defined as 3-O-beta-D-glucopyranosyl protobassic acid 28-O-alpha-L-rhamnopyranosyl (1-->2)-alpha-L-arabinopyranoside and 3-O-beta-D-glucopyranosyl 16 alpha-hydroxy protobassic acid 28-O-alpha-L-rhamnopyranosyl (1-->2)-alpha-L-arabinopyranoside by a combination of LSIMS, FABMS, 1H and 13C NMR and some strategic chemical transformations.
