Pharmacognosy Magazine, 2015

Background: Liver diseases are on rise and remain a serious health problem. Olax subscorpioidea and Distemonanthus benthamianus are two plants used in Ivorian traditional medicine in the treatment of many diseases including jaundice and hepatitis. Objective: The present study was carried out to assess the hepatoprotective and in vivo antioxidant potentials of the hydro-ethanolic leaf extracts of these plants in carbon tetrachloride (CCl 4)-induced hepatotoxicity in rats. Materials and Methods: The plant extracts at doses of 25 and 100 mg/kg bw, and silymarin (25 mg/kg bw) were intraperitoneally (i.p.) injected once daily for 7 days to different groups of rats. Hepatotoxicity was induced on the 7 th day in all the group animals except control. Rats were sacrificed on the 8 th day and blood was collected. Serum biochemical parameters and antioxidant activity were measured using standard procedures. Histopathological examinations of liver rats were also performed. Results and Discussion: Hepatotoxicity induced with CCl 4 was well manifested by significant increase in serum activities of GOT, GPT, ALP and GGT, and enhancement of total bilirubin and TBARS levels. On the other hand, the level of total protein, albumin, α 1-globulin significantly decreased, and DPPH-free radical scavenging activity and TAP were lowered. Pretreatment with plant extracts and silymarin prevent the toxic effects of CCl 4 by decreasing serum enzyme activities, total bilirubin and TBARS levels and improving serum TAP and DPPH-free radical scavenging potential. Histopathological observations showed almost normal hepatic cells with a mild degree of inflammation, lesser fatty infiltration and absence of necrosis among the rats treated at 100 mg/kg of extracts of both the plants. Conclusion: The results suggest that the hydro-ethanolic leaf extracts of O. subscorpioidea and D. benthamianus possesses hepatoprotective and in vivo antioxidant activity.

Acacia catechu have been shown to possess widespread pharmacological application against multitude of diseases namely cancer, diabetes, liver disorders, and oxidative stress. Objective: We evaluated the hepatoprotective activity of the standardized herbal extracts against tert-butyl hydroperoxide (t-BH) induced toxicity and their mechanism of hepatoprotective action in human hepatocarcinoma cells (HepG2 cell line). Materials and Methods: The hepatoprotective activity was studied by observing the effect of these herbal extracts on t-BH induced reduction in cell viability of HepG2 cells. In addition, the reducing power of the extracts and their ability to scavenge free radicals were evaluated using two antioxidant assay systems: cell free [oxygen radical absorbance capacity (ORAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and [2,2'-azino-bis(3ethylbenzothiazoline-6-sulfonicacid)] (ABTS)] and cell based [cellular antioxidant activity (CAA)]. Results and Discussion: The results obtained showed that these extracts possess significant hepatoprotective activity. This may indicate that the plant extracts contain compounds, which can remove toxic metabolites following t-BH induced toxicity. The extracts exhibited significant antioxidant property as evident by the Trolox values and effective scavenging of DPPH and ABTS radicals. The extracts also demonstrated inhibition of AAPH-induced fluorescence in HepG2 cells. These results indicate the ability of the plant extracts to protect the liver cells from chemicalinduced damage, which might be correlated to their radical scavenging potential. Conclusion: This study demonstrates that these extracts have potential hepatoprotective activity which is mainly attributed to the antioxidant potential, which might occur by reduction of lipid peroxidation and cellular damage.

Liver, the largest organ in the body is being evolv ed to maintain the body’s internal milieu and also pro tect itself from the challenges it faces during its functioning. Since it is involved in the biochemical conversio ns of various endogenous and exogenously administered/ingested substances, there is a possibility of generation of various highly reactive species of fr ee radicals. However, it has an inbuilt system like tissue glutathione (GSH), etc to scavenge them off . Inspite of this the free radicals generated by some hepatotoxins like CCl4 may overpower the protective mechanism of the live r and cause hepatic damage. Though the modern medicinal system has grown phenomenally, the drug f or treating hepatic disease is still a dream. Hence , people are looking at the traditional systems of me dicine for remedies to hepatic disorders.

Hepatoprotective and Antioxidant Effects of Silybum marianum Plant in Rats

International Journal for Agro Veterinary and Medical Sciences, 2011

Licorice has been used in Chinese folk medicine for the treatment of various disorders. Licorice has the biological capabilities of detoxication, antioxidation, and antiinfection. In this study, we evaluated the antihepatotoxic effect of licorice aqueous extract (LE) on the carbon tetrachloride (CCl 4)-induced liver injury in a rat model. Hepatic damage, as reveled by histology and the increased activities of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) activities, and decreased levels of serum total protein (TP), albumin (Alb) and globulin (G) were induced in rats by an administration of CCl 4 at 3 mL/kg b.w. (1:1 in groundnut oil). Licorice extract significantly inhibited the elevated AST, ALP and ALT activities and the decreased TP, Alb and G levels caused by CCl 4 intoxication. It also enhanced liver super oxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), Glutathione S-transferase (GST) activities and glutathione (GSH) level, reduced malondialdehyde (MDA) level. Licorice extract still markedly reverses the increased liver hydroxyproline and serum TNF-α levels induced by CCl 4 intoxication. The data of this study support a chemopreventive potential of licorice extract against liver oxidative injury.

Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and albumin levels were determined to prove the hepatoprotectiveeffect.The enzyme activities were significantly increased in CCl4 treated rats. The four water extract mixtures exhibited significant (P<0.05) protective effect against CCl4-induced hepatoxocity and nephrotoxicity by decreasing the levels of serum markers, specially AST and creatinine , respectively.On the other hand, the serum lipid profiles were slightly improved ; HDL-cholesterol significantly (P<0.05) increased in all the water extract mixtures used.

HEPATOPROTECTIVE ACTIVITY OF AQUEOUS EXTRACT OF OXALIS DEBILIS KUNTH AGAINST CCL 4 - INDUCED LIVER DAMAGE

Objective: To evaluate the hepatoprotective activity of aqueous extract of Oxalis debilis Kunth in carbon tetrachloride (CCl 4)-induced hepatotoxicity in Swiss albino mice. Methods: Hepatotoxicity was induced by CCl 4 30% in olive oil (1 ml/kg intraperitoneally). Mice were treated with aqueous extract of O. debilis at doses of 250 and 500 mg/kg body weight orally for 14 days. There were two groups, pre-treatment (once daily for 14 days before CCl 4 intoxication) and post-treatment (2, 6, 24, and 48 hrs after CCl 4 intoxication). The observed effects were compared with a known hepatoprotective agent, silymarin. Results: Pre-treatment and post-treatment groups of aqueous extract of O. debilis significantly reduced elevated serum levels of serum transaminases, alkaline phosphatase, and bilirubin and increased the level of total protein as compared to CCl 4-treated group. The histopathological study also confirms the hepatoprotection. Preliminary qualitative phytochemical analysis of the plant revealed the presence of phenolic compounds, tannins, flavonoids, and saponins. Conclusion: The results of this study suggest that O. debilis can be used as safe, cheap, and alternative preventive and protective drugs against liver injury. The protective effect observed could be attributed to the presence of various phytochemicals which are responsible for the restoration of liver damage.

Journal of Herbs, Spices & Medicinal Plants, 2012

The galls on Terminalia chebula Retz. (Family-Combretaceae) is a well-known herbal drug used to treat various diseases in Indian System of Traditional Medicine. The dried galls are widely commerce in the Indian market and substituted to galls of Pistacia integerrima Stew. Ex. Brandis. The present study aims to investigate antioxidant and hepatoprotective activity of hexane (TCH), ethanol (TCE) and water extract (TCW) of the galls on T. chebula by employing photochemiluminescence and spectrophotometric methods. The results showed that TCE and TCW significantly inhibited 2,2-diphenyl-1-picrylhydrazyl, nitric oxide and superoxide radical in dose dependent manner. Trent of phenol content was as: TCH < TCW < TCE. A significant correlation was shown by total phenol content and free radical scavenging activity of all extracts. The hepatoprotective effect was assayed in CCl4-induced cytotoxicity in a liver slice culture model. The results revealed that significant depletion was observed in lactate dehydrogenase, lipid peroxidation, antioxidative enzymes superoxide dismutase, catalase, and Glutathione reductase on administration of the TCE and TCW or ascorbic acid as standard in the CCl4induced cytotoxicity in the liver. TCE and TCW extracts of galls on T. chebula have prevented significant oxidative liver damage.

Hepatoprotective activity of Ceriops decandra (Griff.) Ding Hou mangrove plant against CCl4 induced liver damage

Journal of Taibah University for Science

In folklore medicine, Ceriops decandra is used to treat hepatitis. However, a scientific evaluation has not been performed. Thus, the present study was carried out to identify the hepatoprotective activity of plant parts (leaf, bark, collar, flower and hypocotyls) of C. decandra. In vitro antioxidant studies were carried out with DPPH, HRSA, NO, FRAP and LPO assays. The LD 50 was calculated and in vivo hepatoprotective activity was carried out with the leaf extract, which was found to be the most potent. The in vivo hepatoprotective activity was performed as follows: Group 1, control animals; Group 2, carbon tetrachloride (CCl 4)-treated animals; Group 3, silymarin (100 mg kg −1 bw p.o.) treated animals; Groups 4, 5 and 6, C. decandra treatment groups (100, 200 and 400 mg kg −1 bw). Histopathological scores were calculated with standard protocols. Of the selected different plant parts, the leaf extract showed maximum antioxidant scavenging properties. A study of the oral acute toxicity found C. decandra extract to be non-toxic up to 2000 mg kg −1 bw. The in vivo hepatoprotective nature of the leaf extract was identified as dose dependent and the levels of SGOT, SGPT, ALP, bilirubin, CHL and LDH were found to be significantly decreased (p < 0.05) compared with hepatotoxin groups. Histopathological scores did not show any significant variations between control and high dose (400 mg kg −1 bw) of leaf extract-treated animals. Preliminary phytochemical analysis of the leaf extract revealed the presence of phenolic groups, alkaloids, triterpenoids, flavonoids, catechin and anthraquinone. In conclusion, the hepatoprotective nature of the C. decandra leaf extract might be due to the occurrence of unique secondary metabolites and their antioxidant scavenging properties.
