摘要
Background: Thunbergia erecta (Acanthaceae) is the most abundant medicinal plant in different parts of Bangladesh where it is known as “nilghonta”. It has been used as traditional medicine for insomnia, depression and anxiety management. However, no scientific evidence of T. erecta belonging to neuropharmacological activity has been reported. The aim of present study was to investigate in vivo sedative and anxiolytic activities of methanol extract from the leaves of T. erecta in Swiss Albino mice. Methods: Sedative activity of METE was investigated using open field, hole cross and thiopental sodium-induced sleeping time test model whereas anxiolytic activity was screened by elevated-plus maze, light-dark box, hole-board and marble-burying test method in mice at 200 and 400 mg/kg doses. The acute toxicity study and phytochemical analysis of METE also carried out. Diazepam used as the positive control for the following behavioral pharmacology test. Results: METE exhibited significant (p Conclusion: The experimental result indicates T. erecta contains phytoconstituents that possess sedative and anxiolytic activity which traditionally used in insomnia, depression and anxiety management.
