The present work was undertaken to evaluate the antiplasmodial activity of ethanolic leaves extract of traditional medicinal plant Xanthium strumarium in Plasmodium berghei-infected BALB/c mice along with phytochemical screening and acute toxicity test to support its traditional medicinal use as a malaria remedy. The ethanolic leaves extract of X. strumarium (ELEXS) 150, 250, 350 and 500 mg/kg/day demonstrated dose-dependent chemosuppression during early and established infection long with significant (p %26lt; 0.001) repository activity. The oral administration of 500 mg/kg/day concentration showed a maximum of 88.6% chemosuppression during early infection, which was more than that of the standard drug chloroquine (5 mg/kg/day) with 88.3% chemosuppression. However, 60% mortality has been found in this group. The LD50 of ELEXS was found to be 1.5 g/kg/mouse. The administration of 350 mg/kg/day concentration of extract have been found to exert 90.40% chemosuppression during repository infection, which was well comparable to standard drug pyrimethamine (1.2 mg/kg/day) exerting 92.91% chemosuppression. The extract has been found to enhance mean survival time of mice from 21 to 26 days with 250 and 350 mg/kg/day concentrations, while 150 mg/kg/day concentration has been found to sustain all the mice up to 29 days which was similar to the employed standard drug chloroquine (5 mg/kg/day). All these findings support the ethanopharmacological use of X. strumarium as malarial remedy and indicate the potential of plant for active antiplasmodial components.
