Determination Of Anxiolytic And Antidepressant Like Activity Of Hydro Alcoholic Fruit Extract Of Pyrus Communis (L.) And Its Impact On The Memory After Chronic Dosing In Animal Models

The purpose of this study was to evaluate the anxiolytic and antidepressant activity of ethanolic fruit extract of Pyrus communis (pear), in comparison with escitalopram in rodents (rats and mice). Thirty Wistar rats of about 200250gm and albino mice of 25-30gm, male gender were divided into three groups each comprising of (n=10) animal respectively. Control group received distilled water, positive control received 10mg escitalopram & treated group received 200mg/kg/day of Pyrus communis ethanolic fruit extract orally for 30 days. They were evaluated by using the open field test, forced swim test (FST), plus maze test, light and dark test, hole poking test, stationary rod test, water maze test & cage crossing activity. Results were expressed as mean +/- SD. Data was analyzed by using SPSS software (VERSION 21) one way ANOVA followed by Tukey test was used for post hoc analysis. Our result showed that fruit extract had significant antidepressant-like behavior in FST (p<0.001), open field (p<0.05), cage crossing (p<0.001) , significant anxiolytic activity in light and dark box test, plus-maze activity and significantly enhanced learning in water maze and stationary rod test when compared with control. The Pyrus communis fruit extract showed the anxiolytic and antidepressant-like profile in rats and mice. However, further studies need to be carried out in clinical trials for its use in different neuropsychological disorders.
