Banana fruit pulp and peel involved in antianxiety and antidepressant effects while invigorate memory performance in male mice: Possible role of potential antioxidants

Pak J Pharm Sci. 2017 May;30(3(Suppl.)):989-995.


The present study was aimed to investigate the anti-stress and memory enhancing effects of banana (Musa sapientum L.) fruit pulp and peel extract in male mice. Locally bred albino Wistar mice were divided into control and 2 test groups (n=10). Control rats received drinking water while test groups were treated with banana fruit pulp (600 mg/kg; oral administration) and extract of banana peel (400mg/kg; oral administration). Behavioral activities of animals were monitored 14 days post administration of banana pulp and peel extract. Depression-like symptoms were measured by forced swimming test (FST). Anxiety like behavior was monitored using light-dark activity (LDA) test and plus maze activity (PMA) test and memory functions of rats were assessed by morris water maze (MWM) test. Following 2 weeks animals were decapitated and brain was removed for estimation of antioxidant enzymes such as catalase (CAT), super oxide dismutase (SOD) and reduced glutathione (GSH). In the present study both banana peel and pulp increased the time spent in light box and open arm, suggesting anxiolytic effects. A significant decrease in immobility time was observed in FST in both banana pulp and peel treated animals suggesting antidepressant like effects. Moreover, learning and memory assessed by MWM showed decrease in time to reach platform in both short term and long term memory test suggested increased memory function in both banana pulp and peel treated animals as compared to control animals. The activities of all antioxidant enzymes were significantly (p<0.05) greater in banana pulp and peel treated animals than control. It is concluded that both banana pulp and peel have anti-anxiety, antidepressant effect as well as strengthen the memory possibly via its antioxidant mechanism. Therefore, it is recommended that supplementation of banana could be taken a vital role in stress (anxiety and depression) relief and increased in memory function possibly by phyto-antioxidants.
