Abstract
Background: In this study, the potential side effects of Khaya grandifolola (KG) and Enatia chlorantha (EC) were investigated on liver function and hematological parameters of Swiss albino mice infected with malaria.
Method: This study was carried out in part in the Department of Biochemistry, Kwara State University, Malete, and in part in the Department of Biochemistry, Faculty of Life Sciences, University of Ilorin, Ilorin, Nigeria, 2016. Aqueous extracts of both KG and EC were screened for the presence of some phytochemicals using gas chromatography-mass spectrometry. Five groups of eight animals each were used. Group A was administered with only distilled water. Group B was administered with 50 mg/kg body weight of artemisinin-based combination therapy (ACT). Groups C, D, and E were treated with 400 mg/kg body weight of KG, EC and KG-EC combination, respectively. After 28 d, the animals were sacrificed for biochemical analysis.
Results: The levels of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and bilirubin activities were not significantly different (P˂0.05) in all the extract treated animal groups as compared to ACT. However, there was increase in the concentrations of ATL and total bilirubin when compared with that of controls. There was no significant difference (P˂0.05) among Hb, RBC, PCV, WBC, lymphocytes, and platelets compared with ACT. However, they increased as compared to the control groups.
Conclusion: The aqueous bark extracts of KG and EC either in single or in combined form resulted in hepatotoxicity compared to controls. They also have deleterious effects on hematological parameters of the Swiss mice following administration.

Abstract
Background: Malaria is a worldwide threat, which affects millions of people. Although several antimalarial has been reported, they are either not effective or toxic. This study evaluated the antimalarial efficacy and safety of stem bark aqueous extracts of Khaya grandifoliola (KG) and Enantia chlorantha (EC) in Plasmodium berghie (NK65S) infected Swiss mice.
Methods: Forty-two animals were grouped into six groups. Group A (control) comprised uninfected animals given sterile placebo. Group B was infected but untreated. Groups C, D, E, and F were infected and treated with 50 mg/kg artemisinin-based combination therapy (ACT), 400 mg/kg body weight of KG, EC, and the combined extracts (200 mg/ml body weight each) respectively.
Results: Alkaloids, terpenoids, glycosides, phenolics, flavonoids, tannin and saponins were all present in the two extracts. The percentage parasitemia in the treated groups C, D, E, and F was significantly (P˂0.05) reduced from 44%, 24%, 35%, and 31% to 17%, 8%, 9% and 8% respectively. The level of creatinine C (1.33±0.08 g/d), D (2.07±0.15 g/d), E (2.17±0.24 g/d) and F (1.20±0.0.12 g/d) increased significantly (P˂0.05) compared to group A (0.73±0.08 g/d). There was no significant difference in the urea level, potassium and sodium concentrations among all the groups.
Conclusion: The efficacy and renal safety of oral administration of aqueous stem bark extract of KG and EC were confirmed. Therefore, the extracts could be used as alternatives to standard drugs in the management of malaria.
