In this study we investigated the in vivo Hepatoprotective activity of ethanolic extract of Garuga pinnata (EEGP) leaves in Carbon tetrachloride (CCl4) induced hepatotoxicity using wistar rats of either sex as model. Hepatotoxicity was induced by the administration of CCl4 intraperitoneally (0.125ml CCl4 in liquid paraffin (1:1) per 100g body weight). Garuga pinnata leaves extract at different dose levels (200 and 400mg/kg, p.o.) showed the dose dependant hepatoprotective effect and was compared with well known standard hepatoprotective Silymarain (100mg/kg). When groups were treated with CCl4, significant increase in serum biochemical parameters such as Serum Glutamate Oxaloacetate Transaminase (SGOT), Serum Glutamate Pyruvate Transaminase (SGPT), Alkaline phosphate (ALP), Acid Phosphate (ACP), Creatinine and alteration of tissue biochemical parameters such as reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), lipid peroxidation (LPO), and the total proteins were observed. The histopathological examination of the CCl4 treated groups showed sinusoidal congestion, centrilobular necrosis, marked vacuolations and congestion. However, pretreatment with extract of leaves of Garuga pinnata significantly reduced the increased serum levels of biochemical parameters and restored antioxidant defense enzymes level to its normal. Moreover, histopathology of leaves extract treated groups showed normal architecture with minimal sinusoidal congestion. Taken together, our study concludes that EEGP to be a more potential agent for caring liver from CCl4 induced damage.

Hepatoprotective effects ofCalotropis giganteaextract against carbon tetrachloride induced liver injury in ratsEthanolic extract (50 %) of stems ofCalotropis giganteaR. Br. (Asclepiadaceae) at doses of 250 and 500 mg kg-1were studied for hepatoprotective activity in male Wistar rats with liver damage induced using carbon tetrachloride, 2 mL kg-1twice a week. The protective effect ofC. giganteaextract was compared with the standard drug silymarin. Various biochemical parameters such as aspartate amino transferase (AST), alanine amino transferase (ALT), glutathione (GSH), lipid peroxide (LPO), superoxidedismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were evaluated. The results revealed that theC. giganteaextract significantly decreased AST, ALT (p< 0.001) and lipid peroxide (p< 0.01) levels. The antioxidant parameters GSH, GPx, SOD and catalase levels were increased considerably compared to their levels in groups not treated withC. giganteaextract.

Adansonia digitata (Bombacaceae) leaves are used in the treatment of kidney and bladder diseases in ethno-medicine. This research was aimed at justifying its use by isolating the secondary plant metabolites responsible for the observed hepatoprotective activity. Coumarin, terpenoids and steroids were the phytochemicals found in hexane, ethyl acetate and butanol soluble fractions of the crude ethanolic extract of A. digitata leaves. These compounds were isolated by chromatographic technique and their chemical structures were identified by direct comparison of their spectroscopic data with those reported in literature. Stigmasterol, friedelin, scopoletin, β–sitosterol and β–sitosterol-3-O-β-D-glucopyranoside were isolated, identified and characterized by their UV, IR, 1H and 13C-NMR. β – sitosterol-3-O- β-D-glucopyranoside, though a known phytosterol is reported newly in the leaves of A. digitata from Nigeria. The UV and IR of four yet to be identified compounds are also reported. Only the ethylacetate soluble fraction of the crude ethanolic extract of A. digatata leaves was subjected to hepatoprotective activity against carbon tetrachloride – induced liver damage in rats and it showed significant hepatoprotective activity by reducing elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphate (ALP) and lactate dehydrogenase (LDH) levels at a dose of 100 mg/kg and 200 mg/kg body weight (p<0.05). Extract at 100 mg/kg body weight showed better hepatoprotective influence than at 200 mg/kg body weight. Reduction in the effect of toxic carbon tetrachloride by the extract was further supported by histopathological results from liver samples which showed regeneration of hepatocytes.

The present study was designed to assess the possible hepatoprotective activity of the leaf ethanolic extract of coded plant (Code No. 222**) against carbon tetrachloride (CCl4)-induced hepatic injury in Wistar albino rats. The animals were divided into different groups and treated with 222 leaf ethanolic extract at different concentrations for five days. Silymarin, the known hepatoprotective standard compound (100 mg/kg) was administered for five days. Hepatotoxicity was induced by the subcutaneous administration of a single dose of CCl4: Olive oil (2 mL/kg) on days 2 and 3. The administration of CCl4 resulted in marked increase in serum hepatic enzymes such as alanine aminotransferase (ALT), aspartate aminotransferase (AST) and serum bilirubin levels. CCl4 intoxication also resulted in a significant (P=0.05) increase in malondialdehyde (MDA), which is a common marker of lipid peroxidation. The other biochemical parameters such as cholesterol, triglycerides, creatinine, urea and uric acid levels were also increased significantly (P=0.05) compared to normal control group. Changes in serum hepatic enzymes, biochemical parameters and MDA levels induced by CCl4 were reversed by the leaf ethanolic extract of 222 (125 mg/kg) dose. The standard drug silymarin treated group also reversed CCl4-induced changes in biomarkers of liver function and MDA levels. Histopathological studies of the liver samples confirmed the hepatoprotective property of the coded drug 222. It was seen that histopathological damage induced by CCl4 were improved in rat liver, treated with 222 extract. The results of the present study suggested that coded plant (222) leaf ethanolic extract may be used as a hepatoprotective agent against toxic effects caused carbon tetrachloride in the liver.

Abstract Background Limnophila rugosa (Scrophulariaceae) is a perennial aquatic plant used as a diuretic and digestive tonic as well as in the treatment of diarrhea, dysentery, dyspepsia and urinary ailments. Genus Limnophila has been reported as hepatoprotective. The present study was undertaken to evaluate the hepatoprotective activity of the ethanolic extract of L. rugosa aerial part in paracetamol- and carbon tetrachloride-induced (CCl4) hepatotoxicity in albino Wistar rats. Ethanolic extract was subjected to high-performance liquid chromatography (HPLC) analysis for the estimation of phenolic and flavonoid compounds and gas chromatography–mass spectrometry (GC–MS) analysis for phytochemical analysis. The in vitro antioxidant activity was carried out by 2,2-diphenyl-1-picrylhydrazyl, nitric oxide radical and hydrogen peroxide assay. Hepatoprotective potential of L. rugosa was studied in paracetamol (750 mg/mg)- and CCl4 (1.25 ml/kg)-induced liver damage in albino rats at dose 200 and 300 mg/kg using silymarin (100 mg/kg) as standard. Lipid peroxidation, superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) were determined in liver tissue homogenate. Serum biochemical and histopathological examination was performed. Molecular docking analysis was performed to understand the molecular mechanism of hepatoprotective activity. Results HPLC analysis revealed predominance of rutin. GC–MS analysis revealed camphor as principal component. Ethanolic extract exhibited significant concentration-dependent scavenging efficacy. The altered biochemical chemical parameters: aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, bilirubin, cholesterol, albumin, globulin and total protein, were significantly improved at 200 and 300 mg/kg in experimental rats. Extract signified hepatoprotective by decreasing lipid peroxidation and upregulating SOD, CAT and GSH. The findings were well supported by histological analysis. 2-Butyl-2, 7-octadien-1-ol (-5.8) and camphor (-4.8) gave the highest docking score on the transforming growth factor-β1. Conclusions The ameliorative effect of L. rugosa in the rat model of hepatotoxicity could be attributed to its antioxidant potential and bioactive principles such as betulin, 5-hydroxy-6,7,4′-trimethoxyflavone (salvigenin), betulinic acid, ursolic acid, 3-octanol, acetophenone, anisylacetone, caryophyllene, cis-anethole and the compounds camphor and 2-butyl-2,7-octadien-1-ol identified from GC–MS analysis.

Tephrosia purpurea possesses hepatoprotective activity as evidenced by the significant and dose dependent restoring the activities of entire liver cancer marker enzymes, diminution in tumor incidence, decrease in lipid peroxidation (LPO) and increase in the level of antioxidant enzymes (GSH, CAT, SOD, GPx and GST) through scavenging of free radicals, or by enhancing the activity of antioxidant, which then detoxify free radicals. These factors protect cells from ROS damage in NDEA and CCl4-induced hepatocarcinogenesis. Histopathological observations of liver tissues too correlated with the biochemical observations. Thus, present investigation suggested that the Tephrosia purpurea would exert a chemoprotective effect by reversing the oxidant-antioxidant imbalance during hepatocarcinogenesis induced by NDEA and CCl4. Besides Tephrosia purpurea is very much effective in preventing NDEA-induced multistage hepatocarcinogenesis possibly through antioxidant and antigenotoxic nature, which was confirmed by various liver injury and biochemical tumour markers enzymes. The hepatoprotective activity of aTephrosia purpurea of 50 % ethanolic extract was studied using rats. The animals received a single intraperitoneal injection of N-nitrosodiethylamine 200mg/kg body wt followed by subcutaneous injection of CCl4 in a dose of 3 ml/kg body wt.Tephrosia purpureaextract dose dependently and significantly the increase in serum hepatic enzyme levels after NDEAand CCl4 treatment compared to the toxin control group. The results of this study confirmed the antioxidant and hepatoprotective activity of the Tephrosia purpurea extract against carbon tetrachlorideand N-nitrosodiethylamine induced hepatotoxicity in rats.

Liver disease or liver cancer is the sixth most common cancer and the third leading cause of cancer mortality in the world. Hepatitis viral infection, food additives, alcohol, fungal toxins (aflatoxins), toxic industrial chemicals, air and water pollutants are the major risk factors of liver cancer. Moreover, due to high tolerance of liver, HCC is seldom detected at an early stage and once detected treatment faces a poor prognosis in most cases.Fumaria indica possesses hepatoprotective activity as evidenced by the significant and dose dependent restoring the activities of entire liver cancer marker enzymes, diminution in tumor incidence, decrease in lipid peroxidation (LPO) and increase in the level of antioxidant enzymes (GSH, CAT, SOD, GPx and GST) through scavenging of free radicals, or by enhancing the activity of antioxidant, which then detoxify free radicals. These factors protect cells from ROS damage in NDEA and CCl4-induced hepatocarcinogenesis. Histopathological observations of liver tissues too correlated with the biochemical observations. Thus, present investigation suggested that the Fumaria indica would exert a chemoprotective effect by reversing the oxidant-antioxidant imbalance during hepatocarcinogenesis induced by NDEA and CCl4. Besides Fumaria indicais very much effective in preventing NDEA-induced multistage hepatocarcinogenesis possibly through antioxidant and antigenotoxic nature, which was confirmed by various liver injury and biochemical tumour markers enzymes. The hepatoprotective activity of a Fumaria indicaof 50 % ethanolic extract was studied using rats. The animals received a single intraperitoneal injection of N-nitrosodiethylamine 200mg/kg body wt followed by subcutaneous injection of CCl4 in a dose of 3 ml/kg body wt. Fumaria indica extract dose dependently and significantly the increase in serum hepatic enzyme levels after NDEAand CCl4 treatment compared to the toxin control group. The results of this study confirmed the antioxidant and hepatoprotective activity of the Fumaria indicaextract against carbon tetrachlorideand N-nitrosodiethylamine induced hepatotoxicity in rats. In addition to this, studies on molecular aspect of hepatoprotective therapy will give mechanistic information in hepatoprotective therapy and also critical balance should be there between the animal model and clinical research. The hepatoprotective properties of Fumaria indicashould provide useful information in the possible application in hepatic liver disease.
