Anxiolytic-like Effects of the Methanol Extract of Sophorae Fructus

The purpose of this study was to investigate the anxiolytic-like effect of the methanol extract of Sophorae fructus (MESF) using elevated plus-maze (EPM), open field test, and horizontal wire test in mice. MESF was orally administered at doses of 50, 100, 200, or 400 mg/kg to ICR mice 1 h before behavioral evaluation. The control group was given an equal volume of 10% Tween 80, and the positive control group was given diazepam (1 mg/kg, i.p.). The administration of MESF significantly increased the percentage of time spent in open arms and the entries into the open arms of the EPM compared with the 10% Tween 80-treated control group (p
