title: Antioxidant and hepatoprotective effect of Acanthus ilicifolius.
abstract: The alcoholic extract of Acanthus ilicifolius leaves inhibited the formation of oxygen derived free radicals (ODFR) in vitro with IC(50) of 550 microg/ml, 2750 microg/ml, 670 microg/ml and 600 microg/ml (Fe(2+)/ascorbate system), 980 microg/ml (Fe(3+)/ADP/ascorbate system) for superoxide radical production, hydroxyl radical generation, nitric oxide radical formation and lipid peroxide formation, respectively. The oral administration of the extract (250 and 500 mg/kg) significantly reduced CCl(4) induced hepatotoxicity in rats, as judged from the serum and tissue activity of marker enzymes [glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT) and alkaline phosphatase (ALP)]. These results were comparable with those obtained with curcumin (100 mg/kg, p.o.).
