Hepatoprotective activity of Terminalia paniculata against paracetamol induced hepatocellular damage in Wistar albino rats

ObjectiveTo evaluate the hepatoprotective activity of Terminalia paniculata against paracetamol induced hepatic damage in rats.MethodsThe plant material was shade dried, powdered and extracted with ethanol. Liv 52 and silymarin were used as standard drugs and 2% gum acacia as a control (vehicle). Alteration in the levels of biochemical markers of hepatic damage like AST, ALT, ALP and lipid peroxides were tested, and phytochemical tests were also performed.ResultsParacetamol (2 g/kg) increased the serum levels of alanine aminotransfer (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and the lipid peroxides. Treatment of Liv 52, silymarin and ethanolic extract of Terminalia paniculata (200 mg/kg) altered levels of biochemical marker and showed significant hepatoprotective activity. Ethanolic extract revealed the presence of phenolic compound and flavanoids. Our findings suggested that ethanolic bark extract of Terminalia paniculata possessed hepatoprotective activity in a dose dependent manner.ConclusionsTerminalia paniculata possesses hepatoprotective activity. It could be an effective and promising preventive agent against PCT induced hepatotoxicity.
