Figure 3: Antagonistic effect of flumazenil on the anxiolytic-like effect of the aqueous extract of A. multiflora stem bark in rats. Flumazenil (10 mg/kg) or vehicle was administered intraperitoneally. The data is expressed as the mean ± SEM of the percentage of the time spent and the number of entries into the open arms of the elevated plus maze over 5 min test period. * compared to the vehicle-treated control group; # versus the flumazenil treated group, rats per group.
