Taraxacum syriacum (TS) with natural antioxidant and pharmacological activities may be considered for treatment of oxidative stress induced by acetaminophen (APAP). The aim of the present study was to evaluate the ameliorative effects of the ethanol extract of TS root against hepatorenal toxicity induced by APAP in comparison to N-acetylcysteine (NAC) as a standard drug. Thirty male Wistar rat were randomly divided into five groups. Control group; APAP (1g/kg) group; APAP-NAC (160 mg/kg) group and APAP-TS100 and APAP-TS200 groups: APAP plus 100 and 200 mg/kg of TS extract, respectively. After 7 days treatment, serum and liver and kidney tissues were prepared and evaluated. TS extract ameliorated the increased lipid peroxidation level and decreased antioxidant enzymes activities and glutathione level in liver and kidney of APAP-treated rats. Moreover, treatment with the TS extract caused significant reduction in the histopathological damages and high levels of serum biochemical markers of hepatic and renal functions after APAP treatment. This study suggests that theextract of TS roots has dose-dependent ameliorative effect against APAP-induced oxidative damage in liver and kidney due to its free radical scavenging and antioxidant properties. The overall efficacy of the extract at 200 mg/kg dose is comparable with NAC.
