Effects of oleanolic acid and hederagenin on acute alcohol-induced hepatotoxicity in mice

open access: yes, 2018
We studied the effects of oleanolic acid and hederagenin on acute alcohol-induced hepatotoxicity in mice. Oleanolic acid [10 and 20 mg/kg body weight (BW)/d] or hederagenin (10 and 20 mg/kg BW/d) was orally administered to the study group for 1 week.
