This study has evaluated the antimalarial activities of <em>Azadirachta indica</em> A. Juss (Meliaceae), <em>Cymbopogon citratus</em> Stapf. (Poaceae), <em>Moringa oleifera</em> Lam. (Moringaceae), <em>Tithonia diversifolia</em> (Hemsl) A. Grey (Asteraceae) and <em>Vernonia amygdalina</em> Del. (Asteraceae) which are commonly-used for malaria treatment in Uganda.</p> <p><strong>Study Design:</strong> This is an experimental laboratory report on antimalarial activities of some Ugandan medicinal plants for subsequent profiling in an herbal pharmacopoeia and eventual drug development.</p> <p><strong>Place and Duration of Study:</strong> The Animal Research Facility and the Clinical and Research Laboratory, Faculty of Medicine, Mbarara University of Science and Technology, Uganda, between July 2019 and March 2020.</p> <p><strong>Methodology:</strong> The antimalarial activity of the hot infusion of each leaf was evaluated on chloroquine-sensitive <em>Plasmodium berghei</em> ANKA-infected mice using 4-day test at 100 – 400 mg/kg with chloroquine (10 mg/kg) and artemether-lumefantrine (4 mg/kg) as positive controls; and distilled water as negative control. The observed haematological responses of the animals were determined with an automated haematometer.</p> <p><strong>Results:</strong> The results showed dose-dependent activities in the animals treated with the extract of each plant leaf in varying degrees. Thus, <em>V. amygdalina</em> and <em>T. diversifolia</em> showed the highest antimalarial activities with the chemosuppression values of 75% and 66% at 400 mg/kg, respectively. The results of <em>V. amygdalina, T. diversifolia</em> and <em>M. oleifera, </em>extracts gave the lowest ED<sub>50</sub> of 141, 195 and 231 mg/kg, respectively being significantly different from <em>A. indica</em> (ED<sub>50 </sub>319 mg/kg) and <em>C. citratus</em> (ED<sub>50 </sub>346 mg/kg) with <em>V. amygdalina</em> as the most potent extract among the five plant leaves.</p> <p><strong>Conclusion:</strong> The observed activities of the five plants have therefore supported their folkloric uses as antimalarial remedies by the Ugandan traditional medicine practitioners with obvious potentials for drug development.</p> Clement Olusoji Ajayi, Anthony Adebolu Elujoba, Hedmon Okella, Joseph Oloro, Atwine Raymond, Anke Weisheit, Casim Umba Tolo, Patrick Engeu Ogwang ##submission.copyrightStatement## Thu, 13 Aug 2020 00:00:00 +0000
