Investigation of In-Vivo Neuropharmacological and In-Vitro Thrombolytic Activity & Phytochemical Analysis of Ethanolic Extract of Argyria Captiformis Leaves

Abstract

Objectives: Investigation with the crude ethanolic extract of Argyria captiformis leaves was carried out to evaluateits possible thrombolysis and to analyze in -vivo neuro-pharmacological effects as anxiety is a particular form of behavioral inhibition that occurs in response to novel environment events and also phytochemical screening of plant extract. Method: Ethanolic extract of Argyria captiformis Leaves was assessed for sedative and anxiolytic activity on Swiss albino mice and Thrombolytic activity was assessed with human blood and also phytochemical screening test was done by various chemical reagents. Sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and anxiolytic property was evaluated by elevated-plus maze(EPM) tests at 400mg/kg while the peripheral and thrombolytic activity determined by percentage of clot lysis. Result: In anxiolytic study, the extract displayed increased percentage of entry into open arm at the dose of 400mg/kg. The extract produced a significant (P<0.01) increase in sleeping duration and reduction of onset of sleep compared to sodium thiopental at doses (400 mg/kg) .The extract (400 mg/kg) also showed suppression of motor activity and exploratory activity of the mice in both open field and hole cross test. Argyria captiformis alone & Argyria captiformis in combination with Streptokinase demonstrated 38.19±4.76% & 77.45±2.97% clot lysis effect respectively & revealed significant with comparison to both the control agent. The presence of tannins, glycosides, saponins, flavonoids, cardiac glycosides, and phytosterols was determined. Conclusion: The pharmacological profiles of the present investigation of the ethanol extract of A. captiformis indicate that the extract possess good CNS depressant and exhibited considerable thrombolytic as it significantly reduced locomotion, onset of sleep, increased duration of sleep and also presence of, glycosides, cardiac glycosides, saponins, flavonoids ,tannins and phytosterols.
