HEPATOTOXICITY OF THE ETHANOLIC EXTRACTS OF ENANTIA CHLORANTHA ROOT ON WISTAR ALBINO RATS

HEPATOTOXICITY OF THE ETHANOLIC EXTRACTS OF ENANTIA CHLORANTHA ROOT ON WISTAR ALBINO RATS (Biochemistry Project Topics)

ABSTRACT
The root of Enantia chlorantha was assayed for its hepatotoxicity effect. Extracts 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), Alanine aminotransferase (ALT) and alkaline phosphatase (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
