Abstract
The hepatoprotective effect of various fractions (n-hexane, CHCl3, EtOAc, n-BuOH, and H2O) of Ban-zhi-lian derived from Scutellaria rivularis Benth. was studied against carbon tetrachloride (CCl4), d-galactosamine (d-GalN) and acetaminophen (APAP)-induced acute hepatotoxicity in rats. Liver damage was assessed by quantifying serum activities of glutamate oxaloacetate transaminase (sGOT) and glutamate pyruvate transaminase (sGPT), as well as by histopathological examination. The results indicated that the CHCl3 fraction and EtOAc fractions exhibited the greatest hepatoprotective effects on CCl4-induced liver injuries, the CHCl3 fraction and n-hexane fraction are most potent against d-GalN-induced intoxication, and the CHCl3 fraction represented the most liver-protective effect on APAP-induced hepatotoxicity. The pathological changes of hepatic lesions caused by these three hepatotoxicants were improved by treatment with the fractions mentioned above, which were compared to Glycyrrhizin (GLZ) and Silymarin as standard reference medicines.
