Abstract
A novel minor triterpenoid saponin mimusin (3-O-[beta-D-glucopyranosyl- (1-->6)-beta-D-glucopyranosyl]-2 beta,3 beta,6 beta,23-tetrahydroxyolean- 12-en-28-oic acid 28-O-alpha-L-rhamnopyranosyl-(1-->3)-beta-D-xylopyranosyl-(1-->4)-alpha- L- rhamnopyranosyl-(1-->2)-alpha-L-arabinopyranoside was isolated from the seeds of Mimusops elengi, in addition to two known triterpenoid saponins, Mi-saponin A and 16 alpha-hydroxy Mi-saponin A. The structure of the minor saponin was established by comparing its 13C NMR and LS-MS linked-scan, ESI-MS data with FAB-MS of the mimusopsin isolated earlier from the same source.Entities:
