Evaluation of in vivo Hepatoprotective activity of Mimosa rubicaulis (LAM.) against CCL4 Induced Liver Toxicity

The current study was conducted to assess the hepatoprotective activity of different extracts of M. rubicaulis (Lam.) at (200 and 400 mg/kg) doses b.w. against CCl4 induced liver intoxication in Albino Wistar rats. Male or female Wistar rats about 150 and 200 gm body weight were selected for present study. The animals were divided into thirteen groups, six rats in each group. The extracts and Silymarin-treated animal groups significantly reduced the activities of various biochemical markers such as SGPT, SGOT, ALP, and TB which were elevated by carbon tetrachloride (CCl4) intoxication. The extracts of M. rubicaulis (Lam.) showed a dose dependent hepatoprotection activity. Among all the extracts, ethanolic extract produced maximum hepatoprotection (SGPT-83.15 %, SGOT76.82%, ALP-79.33%, TB-80.00%) at a 400mg/kg dose. After CCl4 administration, the levels of hepatic-antioxidant enzymes such as Glutathione (GSH) and Catalase (CAT) were reduced, whereas the level of hepatic lipid peroxidation (-LPO) increased. These hepatic antioxidant enzymes were also restored to normal levels by extracts and Silymarin treatment. The results of the present investigation indicate that all the extracts of M. rubicaulis (Lam.) possess hepatoprotective activity which may be due to the presence of various chemical constituents.
