Abstract

The methanol extract of the leaves of Tabernaemontana pauciflora (METP) was screened to investigate the qualitative phytochemical, in vivo anti-depressant, anxiolytic and in vitro thrombolytic activities. The in vivo antidepressant activity of METP was examined by force swimming test (FST) and tail suspension test (TST), whereas anxiolytic activity was examined by using hole-board test (HBT) and elevated plus maze test (EPM) on mice model. Additionally, qualitative phytochemical assay was performed to identify some secondary metabolites, namely alkaloids, carbohydrates, flavonoids. The in vitro thrombolytic model was used to evaluate the clot lysis effect of METP. In the antidepressant assay, METP (200 and 400 mg/kg) exhibited significant anti-depression activity (P < 0.001) on FST (45.64% and 58.31%) and TST (38.67% and 63.62%) whereas the notable anxiolytic effect was observed in EPM (67.67% and 56.06%) and HBT (35.53% and 50%) in dose dependent manner which compared with control. In in vitro thrombolytic assessment of METP exposed 22.66% inhibition of clot. The current results proposed that METP might be effective in neuropharmacological and thrombolytic response due to the presence of alkaloids, tannins and flavonoids, which required further studies to investigate the mechanism.
