Hepatoprotective Effect

In the present study, the hepatoprotective activity of the unsaponifiable matter (UNSAP) of olive oil, linseed, and sesame oils against CCl4-induced liver toxicity in rats was investigated. In a preliminary antioxidant study, UNSAP showed pronounced DPPH radical scavenging activity (IC50 6.2-10.8 mg/mL). The constituents of UNSAP were determined by GC-MS. The subcutaneous administration of CCl4, caused liver injury. The hepatoprotective effect of UNSAP was comparable to that of α-tocopherol, a standard antioxidant agent. The co-administration of the investigated UNSAP normalized the activities of serum marker enzymes, alanine aminotransferase (ALT), and aspartate aminotransferase (AST). Furthermore, the serum alkaline phosphatase (ALP) activity and hepatic malondialdehyde (MDA) level were found to be alleviated by pre-treatment with the UNSAP. A histopathological evaluation showed marked improvement in the liver of UNSAP- and α-Tocopherol-treated animals. The hepatoprotective effect could be attributed to the antioxidant characteristics of UNSAP.

Orthosiphon Stamineus

Orthosiphon stamineus (OS), Benth. (Lamiaceae) is widely used in Malaysia for treatments of various kidney and liver ailments. In the experiment, DPPH• radicals scavenging, Fe 3+-induced lipid peroxidation inhibiting activities and trolox equivalent antioxidant capacity (TEAC) of methanol/water extract of Orthosiphon stamineus (SEOS) were determined. The results indicated that SEOS exhibited antioxidant, lipid peroxidation inhibition and free radical scavenging activities. The hepatoprotective activity of the SEOS was studied using CCl 4-induced liver toxicity in rats. The activity was assessed by monitoring liver function tests through the measurement of alanine transaminase (ALT) and aspartate transaminase (AST). Furthermore, hepatic tissues were also subjected to histopathological studies. Pretreatment of SEOS (125, 250, 500 and 1000 mg/kg p.o.) dose-dependently reduced the necrotic changes in rat liver and inhibited the increase of serum ALT and AST activities. The results of the present study indicated that the hepatoprotective effect of Orthosiphon stamineus might be ascribable to its antioxidant and free radical scavenging property.

Liver diseases have become a global concern worldwide. Liver injury or its dysfunction is a major health problem. The principal causative factors for liver injury are the availability of hepatotoxic drugs, alcohol consumption, infection, malnutrition, anemia etc. In the present study the hydroalcholic extract of some plants of northern India was evaluated for hepatoprotective activity against chronic paracetamol induced hepatotoxicity in rats. The liver injury was induced by Paracetamol orally at a dose of 500 mg/kg, b.w for entire duration of study. The rats were divided in nine groups. Rats of group I served normal control and received distilled water. Rats of group II served as toxic control and received Paracetamol orally at a dose of 500 mg/kg, b.w of rats. Group III received Silymarin at a dose of 100 mg/kg b.w, and served as standard. The animals of groups IV, V, VI, VII, VIII and IX served as test control groups. Protective effect of the hydroalcholic extract was assessed by measuring the levels of serum biomarkers such as SGOT, SGPT, ALP, Bilirubin, serum albumin and total protein. Results of this study showed that the treatment of the hydroalcholic extract of plants at 400 mg/kg b.w, showed significant (*** p less than 0.001) reduction in elevated serum enzyme levels compared to paracetamol induced toxic group, indicating the protective role of plants extract against paracetamol induced chronic liver toxicity. Among the all plants Calotropis procera at a dose of 400 mg/kg, b.w showed the most significant hepatoprotective activity.

Ziziphus rugosa Lam. belongs to the family Rhamnaceae and is found chiefly in deciduous and semi evergreen forest of Western Ghats. The present research was undertaken to establish in vitro antioxidant and in vivo hepatoprotective activity of ethanolic extract of Z.rugosa Lam. leaves. The powdered leaves of Z. rugosa were extracted with ethanol and preliminary phytochemical screening was performed for the presence of various phytoconstituents. DPPH assay and β-glucuronidase inhibition assay were selected for the free radical scavenging activity. For the assessment of hepatoprotective activity, alcohol and CCl4 induced hepatotoxicity model were used. The phytochemical analysis of ethanolic extract showed the presence of alkaloids, saponins and flavonoids. The extract exhibited concentration dependent radical scavenging activity with an IC50 value of 61.88 μg/ml and β –glucoronidase inhibition activity with an IC50 value of 70.61 μg/ml. It was speculated that the Z. rugosa Lam. ethanolic extract shows dosedependent hepatoprotective activity which is equivalent with the standard drug Silymarin. The inhibition of free radicals or free radical scavenging activity is significant in the protection against CCl4 and alcohol induced hepatopathy. Hence, it is likely that the antioxidant activity of ethanolic extract of Z. rugosa Lam. might contribute to the hepatoprotective action.

Lumnitzera Racemosa

One new macrolide, racemolide (1), was isolated from an MeOH extract of the leaves of Lumnitzera racemosa with 7 known compounds (2-8) by various chromatographic techniques via silica gel, octadecylsilyl column chromatography and high-performance liquid chromatography. The structure of the new compound was determined through a combination of spectroscopic and chemical analyses. The isolated compounds were evaluated for their antileishmanial, hepatoprotective, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities. Compound 1 showed potent antileishmanial activity at inhibition % value of 67.6 ± 1.24% compared with the clinical drug miltefosine (93.3 ± 4.39%). Compounds 1 and 5 possessed moderate hepatoprotective activity against acetaminophen (APAP)-induced hepatotoxicity using human HepG2 cells at protection % value of 21.70 ± 1.97% and 27.5 ± 1.41%, respectively, compared with the standard glycyrrhizin (69.50 ± 3.53%). Compounds 4, 6, 7, and 8 had high DPPH radical scavenging activity (91.10 ± 4.25, 91.53 ± 0.05, 91.91 ± 0.09, and 86.48 ± 2.87%, respectively), while compounds 3 and 5 showed moderate (45.38 ± 3.62% and 62.20 ± 1.47%, respectively), comparable with the standard trolox (89.21 ± 5.88%). These results suggest that the new compound, racemolide (1), and known compounds (3-8) are valuable as promising antileishmanial, hepatoprotective, and anti-oxidant agents.

The antioxidant activity and hepatoprotective potential of Cirsium setidens Nakai, a widely used medicinal plant, were investigated. The n-butanol (n-BuOH) fraction of leaves and roots of C. setidens had a higher 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity than the other soluble fractions. The n- BuOH fraction of roots of C. setidens had a significant hepatoprotective activity at a dose of 500 mg/kg compared to that of a standard agent. The biochemical results were confirmed by histological observations indicating that C. setidens extract decreased ballooning degeneration in response to CCl4 treatment. The n-BuOH fraction reduced CCl4-induced liver injury in rats, and transcript levels of genes encoding antioxidant enzymes such as glutathione peroxidase 1 (GPO1), glutathione peroxidase 3 (GPO3) and superoxide dismutase (SOD1) were elevated in the livers of rats treated with this fraction (500 mg/kg). Based on these results, we suggest that the C. setidens extract has hepatoprotective effect related to its antioxidant activity.

Folium Microcos (FM), the leaves of Microcos paniculata L., shows various biological functions including antioxidant activity and α-glucosidase inhibitory effect. However, its therapeutic potential in acute liver injury is still unknown. This study investigated the hepatoprotective effect and underlying mechanisms of the polyphenol-enriched fraction (FMF) from Folium Microcos. FMF exhibited strong free radical scavenging activities and prevented HepG2/Hepa1–6 cells from hydrogen peroxide- (H2O2-) induced ROS production and apoptosis in vitro. Antioxidant activity and cytoprotective effects were further verified by alleviating APAP-induced hepatotoxicity in mice. Western blot analysis revealed that FMF pretreatment significantly abrogated APAP-mediated phosphorylation of MAPKs, activation of proapoptotic protein caspase-3/9 and Bax, and restored expression of antiapoptotic protein Bcl2. APAP-intoxicated mice pretreated with FMF showed increased nuclear accumulation of nuclear factor erythroid 2-related factor (Nrf2) and elevated hepatic expression of its target genes, NAD(P)H:quinine oxidoreductase 1 (NQO1) and hemeoxygenase-1(HO-1). HPLC analysis revealed the four predominantly phenolic compounds present in FMF: narcissin, isorhamnetin-3-O-β-D-glucoside, isovitexin, and vitexin. Consequently, these findings indicate that FMF possesses a hepatoprotective effect against APAP-induced hepatotoxicity mainly through dual modification of ROS/MAPKs/apoptosis axis and Nrf2-mediated antioxidant response, which may be attributed to the strong antioxidant activity of phenolic components.

Objective: To evaluate the hepatoprotective effect of ethanolic extract of the root (REE) of Punica granatum.Methods: This study was conducted on adult albino Wistar rats of either sex weighing 150-200 g. Animals were divided into five groups (n=5). Liver injury was produced by carbon tetrachloride (CCl4) 1 ml/kg dissolved in olive oil (1:1) given intraperitoneally on day 1 and day 4 of the study duration of 14 days. Silymarin (50 mg/kg/d) orally was used as standard drug. Test groups received an REE of P. granatum (REE) at doses of 200 and 400 mg/kg/day orally along with CCl4. On the 15th day, all animals were sacrificed, and blood was collected. Liver was sent for histopathological examination. The hepatoprotective effect of REE was evaluated by assessment of physical parameters, histopathological examination and biochemical parameters such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and total serum bilirubin.Results: The administration of REE of P. granatum at doses of 200 and 400 mg/kg/day orally, exhibited a highly significant decrease in the rise of mean serum AST, ALT, ALP, and total bilirubin as compared to CCl4 treated group (p<0.001). Histopathological examination of the liver also suggested hepatoprotective effect of REE of P. granatum by restoration of hepatic architecture toward normal. Decrease in the extent of centrilobular necrosis was observed in REE (200 and 400 mg/kg/day) treated rats when compared to CCl4 treated group.Conclusion: This study demonstrated hepatoprotective activity of REE of P. granatum against CCl4 induced liver injury in rats.
