Total methanol extract of Plantago asiatica seeds showed significant hepatotonic activities against animal model of hepatitis. The methanol extract was further fractionated with petroleum ether, chloroform, n-butanol and water. Among these fractions, methanol extract and water and chloroform fractions exhibited hepatonic activities, whereas petroleum ether and n-butanol fractions appeared to give rise a rather toxicity. Measurements of serum GOT, GPT and duration of sleeping time induced by hexobarbital after $CCl_4$ intoxication indicated that water fraction showed most potent activities.

The purpose of this study was to find the effect of 36 traditional medicinal plant species on hepatoprotective activity screening. For this study, carbon tetrachloride $(CCl_{4})$ intoxificated rats were used. Test extracts were made with the traditional medicinal plants refluxed in 95% MeOH and orally administered to the rats. Sixteen species, such as Mentha arvensis, Sophora japonica, Benincasa hispida, Lonicera japonica (Lonicerae Flos), Agaricus blazei, Epimedium koreanum, Aralia continentalis, Lithospermum erythrorhizon, Cimicifuga foetida, Gastrodia elata, Sanguisorba officinalis, Cephalonoplos segetum, Bupleurum falcatum, Alisma plantago-aquatica var. orientale, Lonicera japonica (Lonicerae Folium) and Sinomenium acutum showed protective effect against increased serum alanine aminotransferase (ALT) and/or serum asparteate aminotransferase (AST) activities.

We previously reported the hepato-protective effect of butanol soluble fraction of methanolic extract of Carthamus tinctorius L. Semen on carbon tetrachloride induced hepatotoxicity. In this study, the active component from the butanol soluble fraction was isolated by column chromatographic separation using Silica gel and Sephadex LH -20 and identified by spectroscopic methods such as Mass, $^1$H - NMR and $\^$13/C-NMR. The hepato-protective effect of the isolated active component on the CCl$_4$-induced liver damaged rats has been evaluated by performing blood chemical analysis and biotransformational enzyme analysis.

In order to evaluate the protective effects of extracts of Mori cortex radicis on carbon tetrachloride-induced hepatotoxicity, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, malondiadehyde values and glutathione S-transferase activity were measured in ICR mice. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride-treatment were markedly increased than normal control but those levels were significantly decreased by the treatment of butanol fraction of Mori cortex radicis mathanol extract. Glutathione S-transferase activity was decreased by carbon tetrachloride than control, but that also inhibited by the treatment of butanol fraction of Mori cortex radicis methanol extract. These results demonstrate a possible hepatoprotective role of extract role of extract of Mori cortex radicis against ${CCl_4}-induced$ hepatoxicity in vivo.

Objective: To examine the in vitro antioxidant and hepatoprotective properties of Amomum xanthoides extract and its fractions. Methods: Methanol extract of Amomum xanthoides was fractionated into three fractions; petroleum ether fraction (PFAX), water fraction (WFAX) and ethyl acetate fraction (AFAX). The antioxidant and hepatoprotective effects of these fractions were compared by in vitro experiments. Results: The total phenols content and DPPH (1 1-Diphenyl-2-picrylhydrazyl) radical scavenging activity was found significant in AFAX when compared with other fractions (PFAX, WFAX). AFAX significantly inhibited NO production by RAW 264.7 cells in LPS-activated condition. In Hep $G_2$ cells, AFAX markedly prevented the leakage of LDH and release of AST against CCl4 challenge. Conclusion: Amomum xanthoides and especially ethyl acetate fraction have potent antioxidative and hepatoprotective properties.

Petasites japonicus (Compositae) is a perennial herb which has been used as treatment of antitussive, expectorant, sedatives, paralysis, diurectics in folk remedies. The pharmacological studies of this natural drug have not yet estabilished. So, we examined anti-lipid peroxidative effects and liver protective effect on $CCl_4$ induced lipid peroxidation and hepatotoxicity in rats. In vivo liver lipid, MeOH Ex. revealed significant increase of anti-lipid peroxidative effects according to concentration dependently. In chemical parameters obtained from serum analysis, MeOH Ex. as a increase of medicine concentration (0.25 g/kg, 0.5 g/kg, 1.0 g/kg), GOT, GPT, AlP decreased. In 0.5 g/kg GPT administered group, there was relative in GOT, AlP. Cholesterol decreased in 1.0 g/kg and 1.0 g/kg administered group, BUN decreased relatively in 1.0 g/kg administered group.

Comparative biological activities of 70fr methanol extracts from the main roots and rhizomes of both red and white ginsengs were investigated using several in vitro experimental models. The main root of red ginseng and the rhizome of white ginseng strongly inhibited lipld peroxidation of hepatic microsomes induced by the non-enzymatic $Fe^{+}$ / Ascorbate system. The main root and rhizome of red ginseng markedly inhibited the release of G07, GPT and LDH by $CCl_4$-induced cytotoxicity in primary cultured rat hepatocytes as compared with those of white ginseng. And also, the main root of red ginseng showed a slight differentiating activity on HL-60 cancer cell line. The results suggest that the rhizome of ginseng have potential as a source of medicinal crude drug with possible pharmacolobica1 applications .
