AbstractThe goal of this study was to evaluate the cerebroprotective and cognition-enhancing activities of the aqueousReference or working memory and long-term memory in rodents were tested by experimental paradigms like passive avoidance (PA) and T-maze (TM), respectively. TM and Morris water maze (MWM) were used to screen putative spatial or localization task and the navigation memory-enhancing activities ofThe higher dose (20 mg/kg) of plant extract exhibited significant (p<0.01) antiamnesic activity in the PA and TM models vs. the control. In the MWM test, at probe trial,These results partly substantiate the traditional use of

Memory Enhancing

Bacopa monnieri is a well-known Ayurvedic Indian medicinal plant traditionally used as a memory enhancer. Its memory-enhancing effect is mainly attributed to dammarane triterpenoid saponins. In the present study, two new dammarane-type triterpenoid saponins, bacopaside-XI (1) and bacopaside-XII (2), together with known compounds, bacopaside IV, bacopaside V, and apigenin, were isolated from the aerial parts of the B. monnieri . The structures of the new saponins were elucidated as 3-O-[α-L-arabinofuranosyl(1→3)]-6-O-sulfonyl-β-D-glucopyranosyl pseudojujubogenin (1) and 3-O-{β-D-glucopyranosyl(1→3)[α-L-arabinofuranosyl(1→2)]-β-D-glucopyranosyl}-20-O-α-L-arabinopyranosyl pseudojujubogenin (2) on the basis of extensive investigations of 1D and 2D NMR (HMQC and HMBC), ESI-QTOF-MS/MS spectroscopic methods, and chemical evidences.
