RESULTS
It has been observed from our study that both the MEAS at higher concentration showed significant (p<0.01) reduction in immobility in tail suspension and forced swim model of depression comparable to Escitalopram and Imipramine.
CONCLUSIONS
However further study is needed to understand mechanism of action and to identify active component responsible for antidepressant like activity.
