ABSTRACT

The root of Enantia chlorontha was assayed for its hepatotoxicity effect. Extacts from the root were made using 95% ethanol. The root extracts were administered orally to 15 wistar albino rats and varying doses. 5 rats were kept as control group. The effect of the extracts was determined by assaying for the levels of serum-liver enzymes acting as biochemical makers. Liver enzymes assayed included Aspartate aminotransferase (AST), Alanin aminiotransferase (ALT) and alkaline phophatase (ALP). Comparison of the enzyme levels of the control group with these of the group administered with the rot extract revealed a significant elevation of liver enzyme levels (P
