Acrylamide is a food contaminant with a range of toxic effects. Carnosic acid (C 20 H 28 O 4 ) is a phenolic compound found in plants and has many beneficial effects. In this study, we aimed at investigating the effect of carnosic acid on acrylamide‐induced liver damage. Rats (n = 7) were allotted to control, carnosic acid, acrylamide, acrylamide + carnosic acid groups. Animals were euthanized. Their blood was taken for biochemical analysis, and liver tissue was excised for morphological, immunohistochemical, and immunoblotting analyses. As a result, acrylamide reduced bodyweight, liver weight, catalase, and total antioxidant capacity levels but increased alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, malondialdehyde, total oxidant status, oxidative stress index levels, Nrf2, and Keap1 protein levels. In addition, acrylamide disrupted liver histology leading to vascular congestion, cellular infiltration, necrotic cells, and so forth. Carnosic acid cotreatment ameliorated the altered biochemical parameters, liver histology, Nrf2, and Keap1 enzyme levels. In conclusion, carnosic acid has the potential to be used as a protective agent against acrylamide‐induced liver damage.
