Abstract
Objective: To investigate the hepatoprotective activity of ethanolic extract of leaves of Caesalpenia crista (C. crista) against paracetamol induced hepatotoxicity in rats. Methods: Paracetamol (2 g/kg body weight) was used to induce hepatotoxicity in albino rats. Ethanolic extract of leaves of C. crista was administered at the dose levels of 200 and 400 mg/kg body weight orally for 7 d. Silymarin (100 mg/kg) was used as standard drug. The hepatoprotective effect of ethanolic extract was evaluated by assessment of biochemical parameters such as serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, serum alkaline phosphatase, bilirubin (total and direct), and triglycerides content. Histopathological study of rat liver was also done. Results: Administration of ethanolic extract at doses 200 mg/kg and 400 mg/kg body weight exhibited significant reduction in elevated level of serum marker enzymes, bilirubin (total and direct) and triglycerides when compared to positive control group. Conclusions: It is concluded that the ethanolic extract of C. crista leaves seems to justify the promising hepatoprotective effect on paracetamol induced liver damage in rats.
