- Abstract: Objective: To evaluate the phytochemical present in various solvent extracts from leaves of Ocimum sanctum (L.), Swertia chirayita (L.), Butea monosperma (Lam.) and Stevia rebaudiana (Bert.) as well as antioxidant and anticholinergic activities employing different in vitro models. Methods: Total phenol content of diethyl ether, chloroform and methanolic extracts obtained from leaves of different medicinal plants was determined by Folin-Ciocalteau's spectrophotometric method. Moreover, antioxidant and anticholinergic studies were conducted by four different in vitro methods which included diphenyl picrylhydrazyl radical scavenging, 2,2-azinobis (3-ethylbezoline-6-sulphonic acid), reducing activity by ferrous reduced antioxidant power and anti-acetylcholinesterase assay, in order to ensure pharmacological potential of the plants. Results: The methanolic leaf extract of Ocimum sanctum showed the highest total phenol content which was (21.13±1.04) GAE/g DW and antioxidant activities compared to other plants with the IC
