Evaluation of the Anxiolytic Effect of Methanolic Leaves Extract of Paullinia pinnata Lin in Mice
Journal Title: Journal of Pharmaceutical Research International - Year 2014, Vol 4, Issue 13
Abstract
This study was designed to evaluate the anxiolytic effect of methanolic leave extract of Paullinia pinnata L. in mice. The elevated plus-maze and staircase paradigm were used to assess the anxiolytic activity of the methanolic leaf extract of Paullinia pinnata and diazepam. The results of the elevated plus-maze test showed that the extract at the dose of 50 mg/kg and diazepam significantly (P<0.05 and P<0.005) increased both the number of entries and time spent in the open arm by mice. In staircase paradigm, the extract produced a significant (P<0.05-P<0.0005) dose dependent decrease in the number of steps ascended and number of rearing events compared to the control mice. Diazepam significantly (P<0.0005) reduced the number of rearing events compared to control. The result of the present preliminary study suggests that methanolic leaf extract of Paullinia pinnata may possess an anxiolytic activity.
