Antidepressant activity of aqueous extract of Momordica charantia leaves
Keywords:Depression, Forced swim test, Learned helplessness test, Momordica charantia, Tail suspension test, 5-Hydroxytrytophan induced head potentiation in mice
Background: Depression is a common debilitating illness contributing to increase in morbidity and mortality worldwide. 20% of all depressed patients are refractory to treatment with available antidepressants at adequate doses. Momordica charantia commonly known as Karela is widely used in Indian cuisine. This study was carried out to evaluate its lesser known Antidepressant activity. The objective of this study is to evaluate the Antidepressant activity of Aqueous extract of Momordica charantia leaves.
Methods: This study was done in Department of Pharmacology, JNMC, AMU. Tail Suspension test and 5-Hydroxytrytophan induced Head Potentiation was evaluated in Swiss Albino mice. Forced swim test, Learned Helplessness test and Spontaneous motor activity was noted in Albino Wistar rats respectively at doses of AEMC (Aqueous extract of Momordica charantia leaves) 100mg/kg, 200mg/kg and 300mg/kg.
Results: AEMC at all three doses 100mg/kg, 200mg/kg and 300mg/kg exhibited antidepressant activity by significantly decreasing the immobility time in Tail Suspension test and except 100mg/kg. In forced swim test psychostimulant activity of AEMC was ruled out in Spontaneous motor activity. Number of Escape failures was decreased in Learned Helplessness test at doses of AEMC 200mg/kg and 300 mg/kg. Increase in Head twitches was seen only with AEMC 300mg/kg in 5-Hydroxytrytophan induced Head Potentiation in mice.
Conclusions: Aqueous Extract of Momordica Charantia leaves exhibits Antidepressant activity in animal models of Depression.
