Startling rate of malaria parasite resistance to Artemisinin and its derivatives has led to possible herb-drug combination therapy1. This study assessed the effect of co-administration of artemisinin and Ricinodendron heudelotii leaf extract on certain antioxidants and liver parameters in rats and also phytochemical analysis of different fractions of the extract. 40 male rats were randomly grouped into four and administered: distilled water (Group A), artemisinin only (Group B), artemisinin with R. heudelotii extract (Group C) and R. heudelotii extract only (Group D). Alanine amino transferase (ALT), Aspartate aminotransferase, Alkaline phosphatase (ALP). Total protein were determined using standard methods. Reduced glutathione (GSH), catalase and malondialdehyde (MDA) were determined spectrophotometrically while the qualitative and quantitative phytochemical analysis was also carried out. The results revealed that total protein increased significantly in group C. The activities of ALT and AST were significantly increased (p ≤0.05) in the group administered artemisinin only while their activities were regulated to control level both in group C and D. The liver GSH concentration decreased in the group administered artemisinin only compared to the other treatment groups. Similarly, group A exhibited significant increase (p ≤0.05) in MDA while group C and D showed decrease in MDA and catalase concentration. Histological examination showed that few hepatocytes were necrotic in the group administered artemisinin only while group C only showed mild to moderate central venous congestion and periportal cellular infiltration. The study indicates that the bioactive constituents in the R. heudelotii extract might have a regulatory effect on artemisinin toxicity or collaboratively enhance its activity. Such bioconstituents can further be isolated and characterized for drug development to tackle Plasmodium falciparum resistance.
