Background: Galphimia glauca is an evergreen shrub found across peninsular India, belonging to family Malpighiaceae. Objective: The objective of this study was to assess the in vivo depressant effects and muscle coordination activity of G. glauca stem methanol extract (GGSME). Materials and Methods: The stem methanol extract was administered in Swiss albino mice in 1 day to study the central nervous system (CNS) depressant and muscle coordination activity employing animal models such as sodium pentobarbital-induced sleep test, hole-board test, open field test, pentylenetetrazole (PTZ)-induced convulsions, picrotoxin-induced convulsions, grip strengthening test in mice, and Rota-rod test. Results: The LD50of GGSME was found to be >2000 mg/kg body weight (b.w.). Mice treated with stem methanol extract at 100, 200, and 400 mg/kg, b.w. doses extended the sleeping time induced by sodium pentobarbital (40 mg/kg. b.w., i.p.). The stem methanol extract at 400 mg/kg dose showed a significant (P ≤ 0.001) dose-dependent decrease in the number of rears and head dipping number in the hole-board test. The extract exhibited a significant (P ≤ 0.001) effect on the ambulatory behavior of mice in the open field test and also extended the onset of seizures induced by PTZ (90 mg/kg b.w., i.p.) and picrotoxin (10 mg/kg, b.w., i.p.). The extract also exhibited significant (P ≤ 0.001) effects on muscle coordination in rota-rod and grip strengthening test in mice. Conclusion: The study results conclude that the GGSME has a potential CNS depressant and muscle relaxant effects compared to the standard drugs. |
