Abstract: The present study was designed to screen and evaluate the hepatoprotective and antioxidant activity of ethanol extracts of leaf and bark of Naringi crenulata (Roxb) Nicolson (NCL, NCB) against CCl4 induced hepatotoxicity in rats. Liver functions were assessed by the activities of liver marker enzymes, SGOT, SGPT, ALP, total protein, albumin, globulin, total, conjugated and unconjugated bilirubins. It also exhibited antioxidant activity by showing the increased activity of SOD, CAT, GPx and GRD and decreased in TBARS compared to CCl4 treated groups. Silymarin, a known hepatoprotective drug is used for comparison. The plant extracts were effective in protecting liver against injury induced by CCl4 in rats.

Abstract: Oxidative damage is involved in the pathogenesis of various hepatic injuries. In the present study, the protectivity of methanolic extract of leaves of Adiantum incisum forsk (MEAI), as an antioxidant to protect against CCl4-induced oxidative stress and hepatotoxicity in Albino Wistar rats was investigated. Intraperitoneal injection of CCl4, produced a marked elevation in the serum levels of serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT), alkaline phosphatase (ALP) and total bilirubin, and decrease in the total protein. Histopathological analysis of the liver of CCl4-induced rats revealed marked liver cell necrosis with inflammatory collections that were conformed to increase in the levels of SOD, GPx, LPO and CAT. Daily oral administration of methanolic extract of A.incisum forsk at 100 and 200 mg/kg doses for 10 days produced a dose-dependent reduction in the serum levels of liver enzymes. Treatment with A.incisum forsk normalized various biochemical parameters of oxidative stress and was compared with standard Silymarin. Therefore, the results of this study show that A.incisum forsk can be proposed to protect the liver against CCl4-induced liver damage in rats, and the hepatoprotective effect might be correlated with its antioxidant and free radical scavenger effects.

Abstract: Aim: To investigate the phytoconstituents, acute oral toxicity and hepatoprotective activity of ethanol (90%) extract of Cordia subcordata Lam. (EECS) using CCl4 induced hepatotoxicity in male Wistar albino rats.Methods: The EECS at doses of 100, 200 and 400mg/kg, p.o and the standard drug Liv.52 (40mg/kg, p.o) were administered for 7 days in CCl4 intoxicated rats. The hepatoprotective activity was assessed by using various biochemical parameters like SGOT, SGPT, alkaline phosphatase (ALP) and acid phosphatase (ACP), also total bilirubin and urea along with histopathological studies of liver tissue. The biochemical changes and histopathological studies were observed on 4th and 8th day. Results: EECS at tested doses significantly decrease (P<0.001) the elevated levels of the hepatic enzymes, total bilirubin and urea in a dose dependent manner after 3days whereas it’s subsequent return towards near normal after 7days indicating the recovery of hepatic cells. In the liver sections of the rats treated with EECS extracts for 7 days, the normal cellular architecture was retained as compared to Liv.52, thereby furtherly confirming the potent hepatoprotective effect of EECS.Conclusion: The EECS afforded significant protection against CCl4 induced hepatocellular injury.

Abstract: Carbon tetrachloride (CCl4) intoxicated rats showed significant elevation in serum enzymes, bilirubin and lipid peroxidation of the liver tissues and reduction in serum total protein, superoxide dismutase, catalase, reduced glutathione peroxide activity. Treatment with ethanol extract of Polygala rosmarinifolia whole plant altered the above parameters to the levels of near normal. All the above results were comparable with the standard drug silymarin (100mg/kg) treated group. Thus the present study ascertains that the ethanol extract of Polygala rosmarinifolia whole plant possesses significant hepatoprotective activity.

Abstract: Enhydra fluctuans Lour. an edible herbaceous vegetable plant and widely used in torpidity of liver and in nervous diseases. The different extracts (Pet-Ether extract, Chloroform extract and Ethanol extract) of Enhydra fluctuans aerial parts were studied for its hepatoprotective effect on CCl4-induced hepatotoxic rats. The extracts were referred as PEEF, CEF and EEF respectively. In the toxicity study, all the extracts did not produce any mortality even at the highest dose (2000mg/kg) so 200mg/kg dose was taken as the tested dose. The extracts were found to decrease significantly CCl4-induced elevation of SGOT, SGPT, bilirubin and total cholesterol at the dose of 200mg/kg body weight. But it increased HDL-cholesterol level and liver weight with respect to CCl4 toxic rats. Histopathological profiles of CCl4-induced hepatotoxic liver revealed extensive centrilobular necrosis extending to other necrotic areas, ballooning degeneration with steatosis. The protective effect of PEEF, CEF and EEF (200 mg/kg, p.o.) were confirmed by histopathological examination of liver section of control, CCl4-induced and extracts treated groups of rats. Though all the extracts showed remarkable effect. EEF (200mg/kg, p.o.) treated rats exhibited a significant improvement of hepatocellular architecture over CCl4-induced group as evident from considerable reduction in necrosis and steatosis which is comparable with the standard drug Silymarin (25mg/kg, p.o.).

Abstract: This study investigated the protective effects of a polyherbal formula BCEZ, containing extracts of Bacopa monneiri Linn. Penn., Curcuma longa Linn., Emblica officinalis Gaertn. and Zingiber officinale Rosc., on the carbon tetrachloride (CCl4) induced hepatotoxicity in rats. Hepatic injury was achieved by injecting 0.5 mL kg-1, i.p. of CCl4. The BCEZ at the doses 50, 100 and 250 mg kg-1, p.o. offered significant hepatoprotective action by reducing the serum marker enzymes like Serum Glutamate Oxaloacetate Transaminase (SGOT) and Serum Glutamate Pyruvate Transaminase (SGPT). They also reduced the elevated levels of alkaline phosphatase (ALP). Histopathological studies further confirmed the hepatoprotective activity of BCEZ when compared with the CCl4 treated control groups. The results obtained were compared with silymarin (100 mg kg-1, p.o.), the standard drug. Thus it can be concluded, BCEZ might be a potential herbal agent for its hepatoprotective activity.

Abstract: The present study explores the hepatoprotective activity of various extracts of Ferula asafoetida , Momordica charantia Linn and Nardostachys jatamansi against experimental hepatotoxicity. Polyherbal suspensions were formulated using extracts showing significant activity and evaluated for both physicochemical and hepatoprotective activity in comparison with LIV-52 as standard. Petroleum ether (60-80°), chloroform, benzene, ethanol and aqueous extracts of Ferula asafetida , Momordica charantia Linn and Nardostachys jatamansi were evaluated for hepatoprotective activity against carbon tetrachloride-induced liver toxicity in Wistar rats. Polyherbal suspensions were prepared by the trituration method using a suspending agent and other excipients. Formulation F3 has shown significant hepatoprotective effect by reducing the elevated serum enzyme levels such as glutamate oxaloacetate transaminase, glutamate pyruvate transaminase and alkaline phosphatase. These biochemical observations were supplemented by histopathological examination of liver sections. Various parameters evaluated for all formulations were within the official specifications. Experimental data suggested that treatment with formulation F3 enhances the recovery from carbon tetra chloride-induced hepatotoxicity. From these results it may be concluded that the F3 formulation (containing chloroform, petroleum ether and aqueous extracts of Ferula asafetida , petroleum ether and ethanol extracts of Momordica charantia Linn. and petroleum ether and ethanol extracts of Nardostachys jatamansi ) demonstrated significant hepatoprotective activity, that might be due to combined effect of all these extracts.
