ABSTRACT Sonchus asper (SAME) is used as a folk medicine in hepatic disorders. In this study, the hepatoprotective effects of the methanol extract of SAME was evaluated against carbon tetrachloride (CCl4)-induced liver injuries in rats.
To evaluate the hepatoprotective effects of SAME, 36 male Sprague-Dawley rats were equally divided into 6 groups. Rats of Group I (control) were given free access to approved feed and water. Rats of Group II were injected intraperitoneally with CCl4 (3 ml/kg) as a 30% solution in olive oil (v/v) twice a week for 4 weeks. Animals of Groups III (100 mg/kg) and IV (200 mg/kg) received SAME, whereas those of Group V were given silymarin via gavage (100 mg/kg) after 48 h of CCl4 treatment. Group VI received SAME (200 mg/kg) twice a week for 4 weeks without CCl4 treatment. Various parameters, such as the serum enzyme levels, serum biochemical marker levels, antioxidant enzyme activities, and liver histopathology were used to estimate the hepatoprotective efficacy of SAME.
The administration of SAME and silymarin significantly lowered the CCl4-induced serum levels of hepatic marker enzymes (aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase), cholesterol, low-density lipoprotein, and triglycerides while elevating high-density lipoprotein levels. The hepatic contents of glutathione and activities of catalase, superoxide dismutase, glutathione peroxidase, glutathione S-transferase, and glutathione reductase were reduced. The levels of thiobarbituric acid-reactive substances that were increased by CCl4 were brought back to control levels by the administration of SAME and silymarin. Liver histopathology showed that SAME reduced the incidence of hepatic lesions induced by CCl4 in rats.
SAME may protect the liver against CCl4-induced oxidative damage in rats.

    ABSTRACT: Houttuynia cordata Thunb (Saururaceae) is a traditional medicinal herb used to treat several disease symptoms. The present study was focused on the hepatoprotective effects of H. cordata ethyl acetate extract in experimental mice. Further the antioxidant potential of the extract was also evaluated to substantiate its hepatoprotective properties. Carbon tetrachloride-induced hepatic damage in mice was used to measure the serum biochemical parameters. Morphological changes in hepatocyte architecture were studied by haematoxylin and eosin staining. In vitro alkyl and hydroxyl free radical scavenging assays were performed to evaluate the antioxidant effect. Administration of H. cordata extract significantly reduced the elevated serum levels and regulated the altered levels of serum cholesterol in carbon tetrachloride-treated mice (P<0.05). The morphological changes in hepatocyte architecture were also reversed by H. cordata treatment. Further, the extract showed significant antioxidant actions by scavenging the alkyl and hydroxyl free radicals. The concentration of the extract necessary for 50% scavenging of alkyl and hydroxyl radicals was 15.5 and 410 μg/ml, respectively. H. cordata extract exhibited significant hepatoprotective property in carbon tetrachloride-induced hepatotoxicity in mice. The strong antioxidant activities possessed by the extract might be responsible for such actions.

    ABSTRACT: The present study we investigated the hepatoprotective effects of Olea europaea fruit pulp extract against carbon tetrachloride-induced hepatic damage in experimental mice. Further we explored the antioxidant potential of the extract to substantiate the hepatoprotective properties. Biochemical parameters were analyzed in the serum of experimental mice using respective diagnostic kits. Antioxidant activities were measured following alkyl and hydroxyl radical scavenging assays. Compared with control groups, administration of the extract to carbon tetrachloride-treated mice significantly reduced the elevated serum levels of alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. The carbon tetrachloride-treated morphological changes in hepatocyte architecture were also reversed by extract pretreatment. Further, the carbon tetrachloride-treated increased serum cholesterol levels such as triglyceride and low density/very low-density lipoprotein in the liver were reversed in acute and chronic carbon tetrachloride-treated mice. The extract was also found to significantly increase the serum level of high-density lipoproteins in carbon tetrachloride-treated mice. Furthermore, the extract showed significant in vitro antioxidant actions by scavenging the alkyl and hydroxyl free radicals, substantiating its use in hepatoprotection. The concentration of the extract necessary for 50% inhibition of alkyl and hydroxyl radicals was 72.41 and 52.24 μg/ml, respectively. In conclusion, data from our study suggest that Olea europaea fruit pulp extract could prevent carbon tetrachloride-treated acute and chronic liver degeneration and attenuated the lipid levels elevated by carbon tetrachloride. The hepatoprotective activity exhibited by Olea europaea extract might possibly be through its antioxidant defense mechanisms.
