| Popis: | The partially purified petroleum ether extractable fraction of the whole plant Aerva lanata (PF) was evaluated for the protective effect against liver damage induced by carbon tetra chloride (CCl 4 ) in Sprague Dawley rats. Rats were orally administered with PF (50 and 100 mg/kg body weight) for 14 days before CCl 4 challenge and 100 mg of PF alone for toxicity analysis without CCl 4 administration. The results showed that CCl 4 administration significantly damaged the liver as evident from histopathology and very high activity of serum and liver marker enzymes. It also reduced the antioxidant enzyme status of the animals. PF administration significantly reversed the histopathological changes and restored the elevated activities of liver marker enzymes and also enhanced the antioxidant enzyme activities. The extract also reduced hepatic lipid peroxidation and increased the serum total protein and albumin/globulin (A/G) ratio. Preliminary phytochemical analysis of PF showed the presence of alkaloids. These observations clearly indicate that PF contains antioxidant alkaloids capable of ameliorating the CCl 4 -induced hepatic injury by virtue of its antioxidant activity. |
