Isolation and In Vitro Antiplasmodial Activity of the Ethyl Acetate Extract of Alstonia boonie De Wild Leaves Extract

Bioactive compounds in plants have found a wide application in medicines due to their pharmacological or toxicological effects in man and animals. In vitro anti-plasmodial activity of the leaves of Alstonia boonei was studied to support its traditional use as a remedy for malaria. The ethanol extract from the plant was fractionated into ethyl acetate, chloroform and n-hexane fractions. These were subjected to in vitro...
