Purpose of study: To evaluate the hepato-protective activity of methanolic extract of Melia Azedarach (Root) in ccl4 induced liver damage in rats. Material & Methods: Serum levels of Alanine amino-transferase, Alkaline Phosphatase, Bilirubin and Gamma-GT were analyzed in rats after treatment with extract of Melia Azedarch’s root followed by administration of CCl4 in order to assess the preventive effect of extract on liver damage. In addition, the levels of the enzymes in rats administered with ccl4 followed by 14 days treatment with the plant extract were determined in order to assess the cure of liver damage. In the extract treated animals, there was significant decrease in liver enzyme levels. Results: This observation leads to the conclusion that melia flower extract possesses hepato protective activity. The hepato protective activity of the methanolic extract was compared with standard poly herbal formulation named Jigrine CL. The extract of Melia Azedarch’s root was screened for hepato protective effect. Albino rats were administered with carbon tetra chloride (CCl4) for inducing liver damage. Conclusion: It was concluded that the extract of Melia Azedarach found effective against CCl4 induced liver damage
