Abstract
The detoxification, metabolism, and excretion of various endogenous and exogenous materials occur mainly in the liver. Liver diseases are a global concern, and classified as chronic hepatitis, cirrhosis, and hepatosis. The development of safe hepatoprotective agents remains an unmet need. Therefore, we investigated the antioxidant effects of methanolic and n-hexane fractions of Zilla spinosa (ZSM and ZSH, respectively) and Hammada elegans (HEM and HEH, respectively) against carbon tetrachloride (CCl4)-induced liver toxicity in rats. Antioxidant activity was studied by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. The rats were divided into 11 groups (n=6)-group 1 (control), group 2 (CCl4 only), group 3 (CCl4 + silymarin 10 mg/kg), group 4 (CCl4 + HEM 250 mg/kg), group 5 (CCl4 + HEM 500 mg/kg), group 6 (CCl4 + HEH 250 mg/kg), group 7 (CCl4 + HEH 500 mg/kg), group 8 (CCl4 + ZSM 250 mg/kg),
