Background A liver injury could impair the integration of the body's organ system, which may cause complications that can lead to death. The dried red jujube fruit extract has the potential to protect the liver from toxic substances through its antioxidant properties. Aims To determine and analyze the hepatoprotective effect of dried red jujube fruit extract on aminotransferase levels against acetaminophen-induced acute hepatotoxicity. Methods Male Wistar rats were divided into five groups. The negative control group (G1) received carboxymethylcellulose sodium (CMC-Na) 1%. The positive control group (G2) received acetaminophen. The treatment group G3received dried red jujube fruit extract 70 mg/kg BW + acetaminophen, G4 received dried red jujube fruit extract 140 mg/kg BW + acetaminophen, and G5 received dried red jujube fruit extract 280 mg/kg BW + acetaminophen. Dried red jujube fruit extract was given for 10 consecutive days. Acetaminophen (3 g/kg BW) was given on the ninth day. Blood samples were collected, and aminotransferase levels were measured on the 11th day. Results Kruskal-Wallis comparison test showed significant differences (p < 0.01) between all groups on alanine aminotransferase (ALT; p = 0.003) and aspartate aminotransferase (AST; p = 0.001) levels. Mann-Whitney post hoc test showed significant differences (p < 0.01) between G2:G3, G2:G4, and G2:G5 groups on ALT and AST levels. Pearson correlation test showed a significant negative correlation (p < 0.01; r = -1) between all given doses of dried red jujube fruit extract on ALT (p = 0.000; r = -0.778) and AST (p = 0.000; r = -0.774) levels. Conclusion The dried red jujube fruit extract has a hepatoprotective effect on aminotransferase levels against acetaminophen-induced acute hepatotoxicity at 70 mg/kg BW, 140 mg/kg BW, and 280 mg/kg BW (the most effective dose), and there was a negative correlation between all doses and the aminotransferase levels.
