Indonesian Journal of Pharmaceutical and Clinical Research, 2018
This study was carried out to investigate the protective effect of ethanol extract of Curcuma mangga rhizomes on paracetamol-induced hepatotoxicity. High dose of paracetamol (1.35g/kg bw) was used to induce hepatic necrosis of mice liver. The male mice received ethanol extract of C. mangga rhizomes (100, 200 and 400 mg/kg BW) for 7 days. The hepatoprotective actvity of extract was compared to normal, positive (curcuma) and negative control. The liver function was evaluated by measuring the biochemistry parameters which include alanine aminotransferase (ALT) and aspartate aminotransferase (AST). In addition, histophatological study on hepatic tissue section was also carried out. The C. mangga extract displayed hepatoprotective effect except at dose of 100 mg/kg bw. The increasing of serum levels of AST and ALT were inhibited after treatment with ethanol extract at doses of 200 and 400 mg/kb bw which was comparable with normal and Curcuma ® as positive control (p>0.05). In addition, histological assessment of hepatic tissue demonstrated no liver damage, specially at dose of 400 mg/kb BW. The result indicate that ethanol extract of C. mangga rhizomes has hepatoprotective effect, especially at doses of 200 and 400 mg/kg bw .
Hepatoprotective efficacy of ethanolic extracts of rhizome Curcuma amada Roxb. In experimental rats
Thescope of this study is to evaluate the hepatoprotective efficacy of rhizome Curcuma Amada Roxb (CAR) in CCl4 induced hepatotoxicity in rats. Male Albino Wister rats were divided into six groups (n=6). Group I served as the normal control group and received olive oil (i.p. 0.5 mL/kg b.w.) as a vehicle. Group II served as high dose group and received 400mg/kg b.w CAR. Group III served as the carbon tetrachloride (CCl4) group and received CCl4 (i.p., 0.1 mL/kg b.w., 50% CCl4 in olive oil). Groups IV–VI served as the treatment groups, and they received CARdissolved in distilled water orally at dose levels of 100, 200, and 400 mg/kg b.w., respectively, with CCl4 (i.p., 0.1 mL/kg b.w., 50% CCl4 in olive oil). All the groups were given the respective dosages twice a week for 28 days. The result of the marker enzymes AST, ALT, ALP and TBARS in the serum sample revealed an appreciable increase in groups IV, V and VI with respect to CCl4 treated group. This confirmed the hepatoprotective nature of CAR there by deactivating the phase II detoxifying enzymes, preventing the formation of free radical and protecting the cell membrane from degeneration. The nonenzymatic antioxidants pattern of GSH, GPX and GST showed decreased levels with respect to group III. This confirmed that CAR has induced the GSH antioxidant system by increasing cellular defense against reactive free radicals and other oxidative species. The histological architecture of liver sections in Group-IV–VI showed more or less normal lobular pattern with mild degrees of fatty change, necrosis and lymphocyte infiltration almost comparable to those of control group. These results act as a supporting evidence to exhibit the hepatoprotective nature of CAR.

Curcuma xanthorrhiza is widely used in Indonesia folk medicine to treat liver disorders. This study has evaluated the hepatoprotective activity of standardized ethanolic extract of C. xanthorrhiza. The extract was standardized using GC-MS. The hepatoprotective activity of this extract was studied using ethanolinduced liver toxicity in rats. This respective activity was assessed through monitoring liver function tests through the measurement of alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) and protein content. Further, hepatic tissues were also subjected to histopathological studies. Pretreatment of the standardized C. xanthorrhiza ethanolic extract (500 mg/kg) reduced the fatty liver symptoms and significantly (p < 0.05) inhibit the increase of respective serum enzyme levels. The results of the present study indicated that C. xanthorrhiza possess hepatoprotective effects which could act as an effective treatment for acute hepatic diseases.

Background: Hepatology research has focused on developing traditional therapies as pharmacological medicines to treat liver cirrhosis. Thus, this study evaluated mechanisms of the hepatoprotective activity of Curcuma longa rhizome ethanolic extract (CLRE) on thioacetamide-induced liver cirrhosis in rats. Methods: The hepatoprotective effect of CLRE was measured in a rat model of thioacetamide-induced liver cirrhosis over 8 weeks. Hepatic cytochrome P450 2E1 and serum levels of TGF-β1 and TNF-α were evaluated. Oxidative stress was measured by malondialdehyde, urinary 8-hydroxyguanosine and nitrotyrosine levels. The protective activity of CLRE free-radical scavenging mechanisms were evaluated through antioxidant enzymes. Protein expression of pro-apoptotic Bax and anti-apoptotic Bcl-2 proteins in animal blood sera was studied and confirmed by immunohistochemistry of Bax, Bcl2 proteins and proliferating cell nuclear antigen.
ABSTRACT The liver is a vital organ in the body. It plays a major role in metabolism, including ridding the body of substances that would otherwise be injurious if allowed to accumulate, and excretion of xenobiotics from the body. The endogenous antioxidants defenses from reactive oxygen species are strengthened by natural antioxidants and restore the optimal balance by neutralizing reactive species. The present study aims to highlight on hepatotoxic agents, and prevention of hepatic disorders using Curcuma longa, Trigonella foenumgraecum, Allium sativum, Coffea arabica, Petroselinum crispum, Olea europaea leaves, and Mentha piperita. Curcuma longa showed that hepatoprotective effect against hepatotoxicity induced by paracetamol, diethyl nitrosamine, CCl4, and gentamicin. Also, the hepatoprotective effect of Trigonella foenumgraecum seeds has been elucidated against hepatic disorders induced by γ-radiation, monosodium glutamate, ethanol, CCl4, AlCl3, and diabetes. Allium sativum has been used in the treatment of hepatic disorders. The hepatoprotective effect of Allium sativum has been confirmed against oxidative damage and hepatic toxicity of D-galactosamine, lipopolysaccharide, ethanol, and CCl4, which may be due to the presence of organosulfur compounds. Coffea arabica intake has been inversely related to the incidence of liver diseases. Petroselinum crispum showed a hepatoprotective effect against hepatic disorders induced by CCl4 and diabetes, which may be due to their high content of antioxidants. The leaves of Mentha piperita showed a good hepatoprotection against hepatopathy induced arsenic, anti-tuberculosis drugs, and CCl4 which may be due to their high content of phenolics and flavonoids. Olea europaea leaves extract significantly ameliorated pathophysiological changes induced in the liver by diazinon, carbendazim, and γ-irradiation in rats. It can be concluded that administration of Curcuma longa, Trigonella foenumgraecum, Allium sativum, Coffea arabica, Petroselinum crispum, Olea europaea leaves, and Mentha piperita showed a remarkable hepatic protection against hepatotoxic agents, which may be due to its antioxidant properties of these medicinal plants and herbs. So, Human expose to hepatotoxic agents and the patients with hepatic disorders should be advised to take these medicinal plants and herbs.

The present study examined the protective effects of curcuminoid isolates from Curcuma longa against carbon tetrachloride (CCL 4)-induced hepatic injury in rats. The hepatoprotective effect of the crude extract (150, 300 and 600 mg/kg bw) and curcuminoids (75, 150 and 300 mg bw) was evident by significant increases in the serum antioxidative defence capacities (super oxide dismutase, reduced glutathione, catalase) and reduction in biomarker enzymes of liver integrity (aspartate transaminase, alanine transaminase and alkaline phosphatase) in comparison to the results obtained in the CCL 4-untreated animals. Some of these parameters were completely restored by pre-treatments with curcuminoids. Similarly, the curcuminoids increases the concentrations of total proteins, albumins and ameliorated histological changes observed in CCL 4 injured rats. Therefore, curcuminoid could be considered a novel candidate for the development of new drug against liver diseases.

Azadirachta indica, reported to be antioxidative, is hepatoprotective. This study evaluates the effect of A. indica leaf aqueous extract on antioxidant enzymes (glutathione peroxidase (GPx), superoxide dismutase (SOD) in paracetamol induced hepatotoxicity in Wister rats. Twenty four rats, in four groups, each containing six rats were used. Group A was given normal saline, group B paracetamol (800 mg/kg body weight) and groups C and D paracetamol and graded doses of the extract (400 mg and 800 mg/kg body weight respectively). The animals were weighed before and after experiment. Plasma liver enzymes (alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatases (ALP), plasma and liver homogenate malondialdehyde (MDA), GPx and SOD were estimated. Results showed significant weight increase (P<0.05) in A and D and weight loss in B. ALT, AST and ALP were significantly increased in B compared with A while C and D were decreased compared wth B. Plasma and homogenate MDA were increased while GPx and SOD were decreased in B compared wth A. Groups C and D MDA were decreased with increased GPx and SOD compared wth B. The extract could be a potent antidote to paracetamol induced hepatotoxicity as indicated by the increased GPx and SOD in C and D.
