Background: The ethnopharmacological relevance suggests that the ethnic minorities of India use leaves of Cissampelos pareira L. as a traditional medicine for curing various psychopharmacological disorders.

Objective: To evaluate anti-depressant, anxiolytic, and muscle relaxant activity of hydro-alcoholic extract of Cissampelos pareira.

Methods: Leaves of Cissampelos pareira were extracted using a hydro-alcoholic solvent. The safety of hydro-alcoholic extract of Cissampelos pareira was assessed by acute oral toxicity (OECD 423). The anti-depressant activity was measured using open field test, locomotor test, despair swim test, tail suspension test. The anxiolytic activity was assessed using elevated plus maze and hole board test, and skeletal muscle relaxant activity was assessed using rotarod, grip strength, chimney, and inclined plane test.

Results: No moribund status or mortality was observed in experimental mice up to 2000 mg/kg dose of Cissampelos pareira hydro-alcoholic extract (CPHE). In the open field and actophotometer tests, CPHE 200 and 400 mg/kg treated mice significantly abridged ambulation, number of central squares crossed, total locomotion, and depicted less coordinated movements, and in despair swim and tail suspension tests, CPHE 400 mg/kg treated mice significantly decreased duration of immobility and increased number of climbing, confirming its anti-depressant effect. In an elevated plus-maze test, CPHE 200 and 400 mg/kg increased the open arm exploration, while in the hole board test, CPHE 400 mg/kg treated rats augmented the number of head dips, depicting its anxiolytic effect. In rotarod, grip strength, and inclined plane test, CPHE 400 mg/kg treated mice decreased the fall-off time on a rotating rod, suspended wire, or inclined plane. Furthermore, in the chimney test, treatment with CPHE 400 depicted less coordinated movements in mice; the mice of this group took more time to leave the cylinder, depicting its skeletal muscle relaxant effect.

Conclusion: Based on the results, of this study, it can be concluded that CPHE 400 mg/kg exhibits strong anti-depressant, anxiolytic, and muscle relaxant effects, justifying its traditional uses.

Keywords: Cissampelos pareira, hydroalcoholic extract, acute oral toxicity, anti-depressant activity, anxiolytic activity, muscle relaxant activity.
