Evaluation of Moringa oleifera Leaf Extract on Alcohol-induced Hepatotoxicity

ABSTRACT

A study on the protective effect of Moringa oleifera leaf extract in acute alcohol-induced hepatotoxicity in rats was evaluated. Rats fed alcohol only produced significant increase in the levels of enzyme markers of tissues damage (ALT; AST and ALP); lipid peroxidation (TBARS) and decreased serum vitamin C levels compared to normal control rats. Pretreatment with 100 and 200mg/kg body weight of extract significantly decreased the levels of enzyme markers; lipid peroxidation and markedly increased serum vitamin C level in a dose-dependent manner. Post-treatment with 200mg/kg body weight of extract significantly enhanced the recovery of animals from hepatic damage compared to untreated control. Lipid peroxidation and depletion of vitamin C due to oxidative stress could be the possible mechanisms of alcohol induced toxicity and the protective effect of the extract could be as a result of its ability to inhibit lipid peroxidation and prevent the depletion of vitamins C
