The aim of the current study is to evaluate the antioxidant activity and hepatoprotective activity of hydroalocoholic (70%) extract and ethyl acetate fraction of Ehretia laevis Roxb in wistar rats against paracetamol-induced acute hepatotoxicity. In addition, reducing the power of the extracts and their ability to scavenge free radicals were evaluated by applying 2, 2-diphenyl 2-picrylhydrazyl hydrate (DPPH) and Reducing Power Assay. The hydroalocoholic (70%) extract and its ethyl acetate fraction of Ehretia laevis displayed strong antioxidant activity. The extracts at a dose of 100 and 200 mg/kg, p.o., showed significant dose-dependent protection against paracetamol-induced changes in the serum ASAT, ALAT, ALP, and TP. The hydroalocoholic (70%) extract and its ethyl acetate fraction also showed dose-dependent protection against Paracetamol-induced changes in liver tissue such as fatty degeneration, lymphatic infiltration, and necrosis. Among the extracts tested the ethyl acetate fraction shows better activity than the Hydroalocoholic extract.
