In the present study the effect of Lippia citriodora extract on anxiety behavior was evaluated in adult male rats by elevated plus maze. In experimental study, Lippia citriodora extract at doses 50, 100, 200 and 300 mg/kg was administrated in adult male rats, interperitoneally. The control group was treated saline as vehicle. 30 minutes after treatment, anxiolytic effect of plant was evaluated by elevated plus maze during 300 s. Treatment of Lippia citriodora hydro-ethanolic extract at dose 200 mg/kg increased staying in open arm and ratio of open arm entries to whole arms entries (%OAE) and at doses 50, 100 and 200 mg/kg reduced ratio of time of first entry to open arm to time of first entry to whole arms (%OAT).
