The aim of this investigation was to evaluate the antidepressant activity of the ethanolic extracts of {\textquotedblleft}toronjil azul{\textquotedblright}(Dracocephalum moldavica L.). Methodology: The forced swimming test (FST) and tail suspension test (TST) were performed on CD-1 mice to evaluate the antidepressant activity of the ethanolic extracts. The ethanolic extracts were administered orally at an 80 and 100 mg/kg. The animals were dosed 1, 6 and 24 h before initiating the FST assay and 40 minutes before for the TST assay. Imipramine and fluoxetine were dosed at 15 mg/kg, while the flavonoid quercetin was given an a lower concentration of 10 mg/kg as a positive controls. Results: The extracts of Dracocephalum moldavica L. and significantly decreased the immobility time in the FST and TST assays when compared with the negative control and reported similar values than those obtained with the positive controls. Conclusion: The results obtained indicate that extract of Dracocephalum moldavica L. have antidepressant effect similar to those obtained by.

Introduction: India is a rich source of medicinal plants used therapeutically to treat various disorders including depression. This study was undertaken to evaluate the antidepressant effect of acute and chronic administration of Punica granatum (pomegranate) whole fruit in mice. Methods: We used the aqueous extract of Punica granatum (250 and 500 mg/kg per day), standard drug used was Imipramine (10 mg/kg) and vehicle was gum acacia (10 ml/kg), orally. Four groups of animals were used and each group had six animals. In the acute study drugs/vehicles were administered 60 min prior to the experiments. In the chronic study drugs/vehicles were administered for 14 days and the last dose was given on the 14th day, 60 minutes prior to experiment. Forced Swim Test and Tail Suspension Test were used for testing antidepressant activity. Data was analyzed using one-way ANOVA with drug treatment as the independent factor. Post-hoc comparisons were performed using Dunnett\’s test. Results: In acute and chronic forced swim test as well as acute tail suspension test, duration of immobility was significantly reduced in the PG 500 mg/kg, but not in the 250 mg/kg treated group. In chronic tail suspension test, duration of immobility was significantly decreased in PG 250 mg/kg and 500 mg/kg treated groups. The antidepressant activity of 500 mg/kg was comparable to that of Imipramine 10 mg/kg. Conclusion: The present study suggests that aqueous extract of whole fruit of P. granatum has antidepressant activity at 500 mg/kg. It would be advisable to encourage consumption of pomegranate extract in patients with depression because of its nutritional and functional properties.

Depression affects about up to 20\% of the population across the globe.The present study was designed to screen antidepressant activity of methanolicseed extract of Avena sativa (MSEAS). An in vivo experimental methods were designed such as behavioral models like Forced swim test (FST), Tail suspension test (TST) and based on mechanism of action i.e., Antagonism of Apomorphine induced hypothermia on Swiss male albino mice. MSE AS 100 and 200 mg/kg, p.o were administered daily for 7 days. Fluoxetine 25mg/kg p.o was standard antidepressant drug in behavioral models and Desipramine 20mg/kg p.o in Apomorphine induced hypothermia.The methanolicextract produces a significant antidepressant effect in both FST and TST as they reduce the immobility. It was also found, effective in antagonizing or reversing hypothermia produced by apomorphine. The Anti-depressant activity of methanolic seed extract of Avena sativa was found to be significant at low doses (100mg/kg, po). The present study clearly demonstrated that Avena sativa exerts an antidepressant effect in these two behavioral models. The flavonoid components of MSEAS might be interacting with adrenergic system in mediating the anti depressant effect of Avena sativa.

Key words: Avena sativa, forced swim test, tail suspension test, Apomorphine induced hypothermia.
