Abstract

A new triterpenoid saponin, bacoside A3, a constituent of bacosides the saponin mixture of Bacopa monniera, was isolated and characterized. Its structure was established as 3-beta-[O-beta-D-glucopyranosyl(1-->3)-O- [alpha-L-arabinofuranosyl(1-->2) ]O-beta-D-glucopyranosyl)oxy]jujubogenin by chemical and spectral analyses. The cis-isomer of ebelin lactone was also obtained as one of the artefacts of the aglycone and its structure revised.
