Angelica archangelica (AAA) has been effectively used in folk medicines as a remedy against stomachal and intestinal disturbances, arthritic disease, etc. However, there is still lack of scientific proof about its antioxidant capability. This study aimed at investigating the effects of total AAA against chronic ethanol-induced hepatotoxicity. ICR mice were divided into five groups, each consisting of 10 animals. A single dose of ethanol (70%, 0.1 ml, p.o.) was used to induce hepatotoxicity in these mice which resulted in a significant elevation of the activities of serum GOT and GPT. Treatment of mice with AAA (10, 25, and 50 mg/kg p.o.) after 2 weeks ameliorated the ethanol-induced hepatotoxicity effects. Hepatotoxicity was evidenced by a significant increase in hepatic lipid peroxidation manifested as the presence of malondialdehyde. It was found that AAA inhibits the malondialdehyde formation in mouse liver homogenates both in vitro and in vivo. AAA is cytoprotective agent effective against chronic ethanol-induced hepatotoxicity, possibly through inhibition of the production of oxygen free radicals that cause lipid peroxidation, and hence indirectly protects the liver from oxidative stress.
