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