Abstract: Two dammarane glycosides have been isolated from aqueous extract of the aerial parts of <i>Bacopa monniera</i> Wettst. The chemical structure of one of the compound has been established as 20-<i>O</i>-<img src='/image/spc_char/alpha.gif' border=0>-L-arabinopyranosyl jujubogenin, a novel compound, on the basis of LC-MS, IR, 1D- and 2D-NMR studies. The other compound has been identified as 3-<i>O</i>-<img src='/image/spc_char/alpha.gif' border=0>-L-arabinopyranosyl jujubogenin, which is being reported for the first time from <i>B. monniera.</i> The compounds have been screened for their immunomodulatory potential using NBT reduction and chemiluminescence assay using PMN cells.
