Shade-dried flowers of Sarcostemma brevistigma Wight Syn (SBF) belonging to Asclepiadaceae yielded a rare flavonol glycoside viz., Quercetin 5a prenyl, 3-O-glucosyl, 7-O-(4c-p-coumaroyl) neohesperidoside which were characterized based on chemical and spectral (including 2D NMR) studies. The ethyl acetate fraction of alcoholic concentrate (test sample) of flowers of this plant (SBF) was evaluated for its hepatoprotective and inhibition of lipid peroxidation activities to investigate the scientific basis of the traditional uses. The oral administration in varying doses viz., 125 and 250 mg/kg of aqueous suspension of SBF to rats for 7 days produced significant (P < 0.01) hepatoprotective effect comparable to that of standard drug silymarin. The SBF afforded good hepatoprotection against $CCl_4$ induced elevation levels of serum marker enzymes, serum bilirubin and liver weight. The free radical scavenging effects of SBF and flavonol glycoside (SA) were assigned by $Fe^{2+}$/ascorbate induction method (in vitro), which revealed the inhibition of lipid peroxidation. The SBF and SA showed prominent anti-lipid peroxidation activity ($IC_{50}$ about $\sim$180 mg/ml and 11.0 mg/ml respectively), which was comparable to standard drug curcumin ($IC_{50}$ about $\sim$8.25 mg/ml). Thus the hepatoprotective activity of SB could be correlated to the free radical scavenging property of the flavonol glycoside.

Methanolic extract of the leaves of Cassia tom was evaluated for its hepatoprotective potentials in rats by inducing hepatotoxicity with carbon tetrachloride. The extract at a dose of 400 mg/kg orally showed significant protective effect by lowering the serum levels of transaminase (SGOT and SGPT), bilirubin and alkaline phosphatase (ALP). The effects produced were comparable to that of a standard hepatoprotective agent.

Roots of Rumex crispus (Rc) (Polygonaceae) has been used as therapeutic agents of acute and chronic cutaneous diseases, cathartics, fever and jaundice in folk medicines. Recently, Seeds of Rc has known as a digestive, an anticancer agent and a remedy of acute hepatitis, among many traditional folk medicines. So far it isn't reported about pharmacological effects of Rumecis Semen. The present study describes the preliminary evaluations of biological activities, anti-inflammatory activity (AA, Carrageenan) analgesic activity (writhing test), and hepatoprotective activities ($CCl_4$), of its methanol extract, ethyl acetate fraction and butanol fraction. Among them butanol fraction showed the highest activity in analgesic acivity.

Leaves and stem of Viburnum sargentii for. sterile(Caprifoliaceae) has been used as therapeutic agents as a pain of the joints, skin disease as styptics, analgesics for traditional folk medicines. The present study describes the preliminary evaluation of biological activities-analgesic, anti-inflammatory, hepatoprotective activities, of its methanol extract, ethyl acetate fraction and butanol fraction. Among them butanol fraction showed the highest activity in inflammation and writhing test.

Objectives : This study was to examine the efficacy of GCT on the hepatoprotective effect in the liver function and immune octivity. Methods : The experiment to investigate the hepatoprotective effect of GCT on the liver damage was conducted with D-galactosamine. The experiments to verify the effects of GCT on the immune activity were conducted by carbon clearance assay, plaque-forming cell SRBC assay of IgM, lymphoproliferation assay of T and B cells, and adherence and phagocytosis of mocrophages. Results: In the damage of liver induced by D-galactosamine, GCT carried hepatoprotective effect on AST. In carbon clearance assay GCT showed significant effect on phagocytosis of Kuffer cells. In the plaque-forming cell assay, GCT improved the formation of IgM. In the lymphoproliferation assay, GCT activated the formation of T and B lymphocytes. In macrophages, GCT activated adherence and phagocytosis. Conclusion : Though further study is needed, our findings suggest that GCT could be recommended as hepatoprotector and immune modulator for liver disease.

In this study, the liver protective effect of the hot water extracts of Scutellaria radix (SR) was investigated. The SR exhibited a hepatoprotective activity against $CCl_4$-induced liver damage in Sprague-Dawley (SD) rats and Chang cell. And the SR also showed significant decrease of malodialdehyde (MDA) and increase of glutathion (GSH), catalase activity in rat liver homogenate. The expression of cytochrome P450 2E1 (CYP2E1), measured by RT-PCR and western blot, was significantly decreased in the SR treated SD rats and Chang cell. But $CCl_4$ and SR has no significant effect on 1A1 and 3A1 isoform of cytochrome P450. Based on these findings, it is suggested that hepatoprotective effects of SR possibly related to antioxidative effects and downregulation of CYP2E1 expression.

The protective effects of the water extracts of nine kinds of medicinal herbs, which have been reputed to having the hepatoprotective activity in Chinese herbal medicine, on BNL cl.2 cells using a MTT assay were investigated. Five extracts including Coriolus versica, Curcuma longa, Phellinus linteus, Po-lygonum aviculare, and Salvia miltiorrhiza showed the protective effects on BNL cl.2 cells damaged by $CCl_4$ with $ED_{50}$ values of less than $100\;{\mu}g/ml$. Silymarin had been used as a positive control.

Chlorpyrifos (CPF) is one of the most heavily used organophosphate pesticides and is useful as an insecticide drug. However, CPF also causes toxic effects in nontarget organisms, including humans and animals. Jageum-Jung (JGJ) is a traditional oriental medicine, composed of five specific herbs with antioxidant and hepatoprotective properties, used for detoxification. In the present study, highly concentrated CPF was orally administrated to male Institute of Cancer Research mice to produce acute toxicity, and the protective effects of JGJ administration were investigated through statistical analysis of changes in body and organ weights and serum biochemical parameters. JGJ caused body and organ weights to recover and reduced the levels of serum biochemical parameters indicative of liver damage, such as glutamic oxalate transaminase, glutamic pyruvate transaminase, alkaline phosphatase, lactic dehydrogenase, urea, glucose, total cholesterol, and triglyceride, that had been increased by CPF treatment. Our results demonstrated that JGJ ameliorates the effects of acute chlorpyrifos-induced toxicity. Therefore, JGJ has the potential to be used as a traditional medicine to alleviate insecticide toxicity.

Objectives : This study was carried out to investigate the hepatoprotective effects of mixture with Hovenia dulcis Thunb (HDT) and Acer tegmentosum Maxim(ATM) on D-galactosamine-induced liver failure in rats. Methods : The animals were divided into 4 groups: control, with liver failure and no treatment; H1A1, with liver failure and oral treatment with HDT 1 and ATM 1; H1A2, with liver failure and oral treatment with HDT 1 and ATM 2; H1A4, with liver failure and oral treatment with HDT 1 and ATM 4. The animals were treated for 3 weeks and then examinations of change of body weight, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase ($\gamma$-GTP), total cholesterol, triglyceride, total bilirubin, superoxide dismutase (SOD), catalase, histopathologic change, and complete blood count (CBC) were performed. Results : All experimental groups had significantly decreased AST in serum and markedly increased activity of SOD as compared with the control group. H1A1, and H1A4 significantly decreased ALT in serum and H1A4 at 2 weeks was significantly higher on the change of body weight as compared with the control group. In histopathologic change of liver tissue by light microscopy, all experimental groups showed recovery effects of liver cells which were damaged by D-galactosamine. Conclusions : Based upon these results, it could be assumed that a mixture of HDT and ATM has hepatoprotective and antioxidative effects on D-galactosamine-induced liver failure. Therefore, a mixture of HDT and ATM might be utilized as a protective agent in therapy for liver diseases.
