Effect ofMusa sapientumStem Extract on Animal Models of Depression.
BACKGROUND
Musa sapientum, the banana plant, has shown to possess antioxidant activity in previous studies. Oxidative stress has been linked to the pathogenesis of major depressive disorder (MDD) with evidence of increased serum levels of oxidative stress biomarkers in MDD patients.


OBJECTIVE
The present study aimed to evaluate the antidepressant activity ofM. sapientumstem extract (MSSE) in experimental models in mice.


METHODS
Forced swim test (FST) and tail suspension test (TST) were carried out in five different groups (n= 6/group) of mice. The vehicle, standard drug, and the three test groups were orally administered distilled water (10 mL/kg), fluoxetine (25 mg/kg), and incremental doses of 25, 50, and 100 mg of MSSE, respectively, 45 min prior to the experiment.


RESULTS
On FST, the duration of immobility in control group, which was 161.5 ± 6.78 (in seconds, mean ± standard error of mean [SEM]), decreased to 149.33 ± 2.70 (25 mg/kg MSSE), 120.17 ± 8.35 (50 mg/kg MSSE), and 45.17 ± 4.11 (100 mg/kg MSSE) in the treated groups. On TST, the duration of immobility in control group, which was 173.83 ± 12.65 (mean ± SEM), decreased to 163.17 ± 6.91 (25 mg/kg MSSE), 139.0 ± 5.9 (50 mg/kg MSSE), and 124.0 ± 4.42 (100 mg/kg MSSE) in the treated groups. The difference in the duration of immobility was statistically significant at middle and higher doses, i.e. 50 and 100 mg/kg MSSE (P< 0.05) respectively, when compared with the control group in both the tests.


CONCLUSIONS
A significant antidepressant-like activity was found in MSSE, which could be a potential natural compound for use in depression.


CONCLUSIONS
The five groups - vehicle, standard drug, and the three test groups were administered distilled water (10 mL/kg), fluoxetine (25 mg/kg), and incremental doses of 25, 50, and 100 mg ofMusa sapientumstem extract (MSSE), respectivelyThe duration of immobility decreased in the treated groups as compared to the control group on both, forced swim and tail suspension, testsThe difference in the duration of immobility was statistically significant at middle and higher doses, i.e., 50 and 100 mg/kg MSSE (P< 0.05), when compared with the control group in both the tests.Abbreviations Used: MDD: Major depressive disorder; MSSE:Musa sapientumstem extract; FST: Forced swim test; TST: Tail suspension test; GSH: Glutathione, MDA: Malondialdehyde; SOD: Superoxide dismutase.
