Liver, an important organ of metabolism, is damaged when exposed to chemicals, toxins, infectious agents, drugs and food additives. Arachis hypogaea (peanut) being organic may have free radical scavenging activity, which could protect the liver from damage. Objective: To evaluate the effect of Arachis hypogaea on liver marker enzymes such as serum AST(aspertate transaminase) and
ALT(alanine transaminase) and histology of liver in Wistar albino rats. Methods: Twenty healthy Wistar albino male rats (120 – 150 grams, 90 – 120 days old) were acclimatized for 14 days and divided equally into control group (n = 10) and experimental group (n = 10). Control group received standard pellet for 21 consecutive days. The experimental group received peanut powder 500mg/kg body weight/day; orally) mixed with food for the same period. All the animals were killed on 22nd day. Blood and liver samples were collected. Levels of serum AST, ALT and bilirubin were estimated and the liver was processed for histology. Results were statistically analyzed by
2 sample t-test. Results: Final body weights were significantly (p
