- Abstract
This research evaluated the anxiolytic and antidepressant-like effects of a hydroethanolic extract from the leaves of Annona coriacea (EHFAC) and caffeic acid (CA). Mice were intraperitoneally treated with saline, EHFAC (1, 10, 20 mg/kg) or CA (0.15 mg/kg) and subject to the elevated plus-maze, open field, rota-rod, forced swimming and reserpine-induced akinesia tests. Pro-convulsant and anticholinergic effects were also evaluated. EHFAC presented anxiolytic-like effect on the elevated plus-maze, which was partially reversed by flumazenil. A similar effect was observed with CA. In the forced swimming test, EHFAC and CA reduced the immobility time of mice; such effect was potentiated when EHFAC or CA were associated with imipramine, bupropion and fluoxetine. The antidepressant-like effect was reinforced as EHFAC partially reversed the reserpine-induced akinesia. In addition, a pre-treatment with EHFAC and CA did not decrease the latency to 1st seizure of animals that received a sub-convulsive dose of PTZ, nor reduced the intensity of oxotremorine-induced tremors. Taken together, the results indicate that EHFAC and CA have anxiolytic and antidepressant-like effects, which involve important neurotransmitter systems, such as GABAergic and monoaminergic ones, being devoid of side effects, commonly associated with classical psychotropic drugs., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.
