Abstract
Bacopa monniera Linn. or Brahmi, a plant in the family Scrophulariaceae, is used as a traditional medicine for memory improvement, dementia like anxiety, depression, epilepsy etc. for a long time in Bangladesh. This study evaluated the anxiolytic effects of the methanolic extract of B. monniera (MEBM) in animal models of anxiety. For the further tests and phytochemical screening, the whole plant of B. monniera extracted following maceration method. The extract was evaluated for anxiolytic activity using light/dark box, elevated plus maze, marble burying and rota rod tests in mice at the doses of 50, 100, and 200 mg/kg body weight. Diazepam (1.0 mg/kg), an anxiolytic drug used as standard drug. MEBM showed a strong and dose-dependent anxiolytic effects in animal models of anxiety. MEBM significantly increased the time spent in the light compartment, the latency time, and the entries of open arms in light/dark and elevated plus maze tests. In addition, MEBM also significantly decreased the number of buried marbles in marble burying test and increased the time of performance in rota rod test (pKeywords
