The goal of this study is to evaluate a formulation of Agunmu made from M. indica, A. repens, E. chlorantha, A. boonei, and B. ferruginea, sold in the open market and commonly used for the treatment of malaria by the locals, for its antimalarial effects and to determine the active principles that may contribute to the antimalarial effect. The ethanolic extract obtained from this formulation (Ag-Iba) was analyzed, using TLC, LC-MS, and Tandem-MS techniques, to determine its phytochemical properties. The extract was tested in vitro against representative bacteria strains, cancer and normal human cell lines, and susceptible (D6) and resistant (W2) Plasmodium falciparum. In subsequent in vivo experiments, graded doses of the extract were used to treat mice infected with chloroquine-susceptible (NK-65) and chloroquine-resistant (ANKA) strains of Plasmodium berghei. Bacteria growth was monitored with a disc diffusion assay, cancer cell viability was determined with MTS assay, and percentage parasitemia and parasite clearance were determined by microscopy. Bound heme content, host mitochondria permeability transition (mPT) pore opening, F0F1-ATPase, and lipid peroxidation were determined via spectrophotometry. Indices of oxidative stress, anti-oxidant activities, toxicity, cell death, and inflammatory responses were obtained using biochemical and ELISA techniques. The histology of the liver and spleen was performed using the standard method. We elucidated the structures of the critical active principles in the extract to be flavonoids: kaempferol, quercetin, myricetin, and their glycosides with little or no detectable levels of the toxic Aristolochic acids that are found in Aristolochia repens, one of the components of the formulation. The extract also showed anti-plasmodial activity in in vitro and in vivo models. Furthermore, the extract dose-dependently decreased mitochondrial dysfunction, cell death, and inflammatory and oxidative damage but increased antioxidant potentials. Presumably, the active principles in the extract work as a combinatorial therapy to elicit potent antimalarial activity. Overall, our study unraveled the active components from a commercial herbal formulation that could be reformulated for antimalarial therapy.<\/jats:p>","DOI":"10.3390\/molecules29235658","type":"journal-article","created":{"date-parts":[[2024,11,29]],"date-time":"2024-11-29T08:24:14Z","timestamp":1732868654000},"page":"5658","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Elucidation of the Active Agents in a West African Ground Herbal Medicine Formulation That Elicit Antimalarial Activities in In Vitro and In Vivo Models"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4973-0376","authenticated-orcid":false,"given":"Solomon","family":"Owumi","sequence":"first","affiliation":[{"name":"Cancer Research and Molecular Biology Laboratories, University of Ibadan, Ibadan 200005, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8882-1601","authenticated-orcid":false,"given":"John","family":"Olanlokun","sequence":"additional","affiliation":[{"name":"Laboratories for Biomembrane and Biotechnology Research, Department of Biochemistry, University of Ibadan, Ibadan 200005, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7381-9506","authenticated-orcid":false,"given":"Bocheng","family":"Wu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta, GA 30332, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abiola","family":"Duro-Ladipo","sequence":"additional","affiliation":[{"name":"Foetal Programming Unit, Department of Physiology, University of Ibadan, Ibadan 200005, Nigeria"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sophia","family":"Oyelere","sequence":"additional","affiliation":[{"name":"Wheeler High School Magnet Program, Marietta, GA 30068, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shabana","family":"Khan","sequence":"additional","affiliation":[{"name":"NCNPR, School of Pharmacy, University of Mississippi, University, MS 38677, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2248-9551","authenticated-orcid":false,"given":"Adegboyega","family":"Oyelere","sequence":"additional","affiliation":[{"name":"School of Chemistry and Biochemistry, Georgia Institute of Technology, Atlanta, GA 30332, USA"},{"name":"Parker H.
