摘要：

A new triterpenoid saponin, bacoside A(3), 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-arabinofuranosy(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.
