"Effect of Triterpenoid Saponins from Bacopa monniera on Scopolamine-Induced Memory Impairment in Mice" Yun Zhou1, Ling Peng2, Wei-Dong Zhang3, De-Yun Kong4, Planta Medica, 2009; 75: 568-574

Abstract

Three new saponins, bacopasides IX−XI (1-3), together with their known analogues bacopaside I (4), bacopaside II (5), bacopasaponsin C (6), and bacopasaponsin D (7), were isolated from the whole plant of Bacopa monniera. Compounds 3, 4, and 6 showed nootropic activity when tested in the Morris water maze test and step-down test of scopolamine-induced memory impairment in mice.

Given the mode of action this suggests, maybe brahmi can be utilised as a treatment or preventative when anticholinergic compounds are causing problems.
