The present study was undertaken in order to elucidate the effect of ginseng butanol fraction on ethanol induced hepatic aniline hydroxylase activity in rat. Ginseng butanol fraction increased the hepatic aniline hydroxylase activity which is inhibited by ethanol addition in the enzyme assay system, whereas not shown the ginseng effect in ethanol absence condition in vitro. It was found that ginseng butanol fraction improved the affinity of aniline hydroxylase under presence of ethanol in the reaction mixture. On the contrary ginseng butanol fraction showed significant decreasing effect on aniline hydroxylase activity induced by ethanol administration. These results suggest that ginseng butanol fraction regulate the hepatic aniline hydroxylase activity which is induced by ethanol consumption.

The effect of ginseng butanol fraction (total sponin) on the absorption rate of ethanol in rat intestine was examined. Ginseng butanol fraction showed inhibitory effect on the intestinal absorption of ethanol in situ as well as in vitro test. Ginseng butanol fraction markedly decreased the ethanol blood level, delayed onset time of ethanol effect and shortened sleeping time when it was adminstered orally together with ethanol. These results suggest that ginseng may alter the ethanol blood level by decreasing the intestinal absorption of ethanol.

To investigate the antioxidative effects of an etbylacetate fraction extracted from the flowers of Chrysanthemum indicum L. (Chrysanthemi Flos) on the antioxidative system and lipid profiles of rats with ethanol induced hepatotoxicity. Sprague-Dawley rats weighing $100\~150$ g were divided into 5 groups: normal group (NOR), Chrysanthemi Flos EtOAC fraction (200 mg/kg) treated group (S1), $35\%$ etbanol (10 mL/kg) treated group (S2), Chrysanthemi Flos EtOAC fraction (200 mg/kg) and ethanol concomitantly treated group (S3) and Chrysanthemi Flos EtOAC fraction (400 mg/kg) and ethanol concomitantly treated group (S4), respectively. The antioxidative activity of each fraction was decreased in order of EtOAC, n-hexane, n-BuOH, water and chloroform. The growth rates and feed efficiency ratios were decreased by ethanol treatment, but were gradually restored to similar levels as in the NOR group by administering Chrysanthemi Flos EtOAC fraction. The whole blood concentrations of total cholesterol and LDL-cholesterol, and the activities of ALT and AST that were elevated by ethanol were significantly decreased in the Chrysanthemi Flos EtOAC fraction treated groups. It was also observed that the activities of SOD, catalase, xanthine oxidase and GSH-Px elevated by ethanol in rat liver were markedly decreased in the Chrysanthemi Flos EtOAC fraction treated group as compared to S2. These results suggest that Chrysanthemi Flos EtOAC fraction has possible protective effects against ethanol induced hepatotoxicity in rat liver.

In order to study antioxidative acton of garlic, alliin, scordinin, garlic oil, ethanol fraction and non-kaolin fraction which have been discovered from garlic until now were extracted and isolated, and each fraction was utilized as the experimental materials. Antioxidative action of each fraction was compared through the in vitro and in vivo experiments. Electron donatingability on $\alpha$, $\alpha$-diphenyl-$\beta$picrylhydra-$\chi$yl, the inhibitory effect of lipoperoxide formation by TBA and peroxide value were measured and analyzed. RESULTS : 1. When observed antioxidative ability by EDA value, ethanol fraction of garlic components showed the strongest reaction as 15.25. 2. In vitro experiment with TBA value, garlic oil, alliin and ethanol fracton showed distinctive effect on inhibitory effect of lipoperoxide formation. 3. Comparing with the inhibitory effect of lipoperoxide formation with TBA value in vivo, the ethanol fraction was the most effective in the blood or liver by intraperitoneal administration, whereas the ethanol fraction in the blood and non-kaolin fraction in the liver was most effective each other by orally administration. 4. In vitro experiment with peroxide value, garlic oil was distinctive effect on the inhivitory effect of lipoperoxide formation, which was a similar to the trend of TBA value in vitro. 5. Examining the induction time for the first period of lipoperoxide formation in vitro, garlix oil, ethanol fraction and alliin were effective, which was a similar to the trend of TBA value and peroxide value in vitro.

In case of ethyl acetate fraction, it was the highest electron donating ability to DPPH radical, 39.06±0.34%, and then water fraction of 36.71±5.55%, ethanol fraction of 29.77±2.57%, gradually. Electron donating abilities revealed significant difference (p<0.05) between the solvents.

In a preliminary screening of plant extracts for the antigastritic and anti- Helicobacter pylori (H. pylori) actions in rats, the ethanol extract of Amomi Semen (AS) showed positive activity in HCl Ethanol-induced gastric lesions and H. pylori. Among the systematic fractions of hexane, chloroform, butanol and water, the most potent butanol fraction significantly reduced HCl, Ethanol-induced gastric lesions at the oral dose of 350 mg/kg. Also butanol fraction has an inhibitory effect on the growth of H. pylori $(MIC=1.43\;{\mu}g/mL)$. In pylorus ligated rats, butanol fraction showed decrease in the volume of gastric secretion and acid output, of which effects were stronger in other fractions. We isolated 6 subfractions by column chromatography. The protective effects of 6 subfractions of Amomi Semen were also significant in the HCl, Ethanol induced gastric lesion model. These results might suggest that they had inhibitory action in gastric lesion through inhibition of gastric acid secretion. Butanol fraction of AS can be applied as treatment of H. pylori. Butano fractions and ethanol extract of AS was carried out or the development of a new gastroprotective supplementary product.

The present study was undertaken to investigate an effect of ginseng butanol fraction(total saponin) on the hepatic ethanol metabolism, we used experimental animals for the subject of study. When, in case of ADH and MEOS, ginseng butanol fraction was added, enzyme activity was increased in a small dose, and on the contrary, in a large dose, showed inhibitory effect. in catalase, the activity showed no significant effect by adding ginseng butanol fraction. In the light of kinetic aspect, when, in reaction mixture, ethanol and ginseng butanol fraction were concurrently added and reacted, Km value of ADH and MEOS was decreased. After pretreated with ginseng butanol fraction and inducement of acute toxic state by ethanol, the activities of ADH and MEOS were increased to an extent of about 25% compared to controls. But catalase activity was not significantly affected. In case that ginseng butanol fraction was given to mice fed with 5% ethanol instead of water for 60 days, the activities of ADH and MEOS were increased about 20% to 50% compared to ethanol-treated group. On the contrary, catalase activity was not affected. But blood concentrations of ethanol were decreased due to ginseng butanol fraction treatment. All these observations suggested that reduction of ethanol blood concentration should be dependent upon increased activities of ADH and MEOS. Thereby it suggests the recovery from alcohol intoxication can be prompted by treatment with ginseng.

The antioxidant activity of ethanol extracts from defatted perilla flour was investigated by measuring peroxide value of perilla oil during storage at $45^{\circ}C$. The antioxidant activity of ethanol extracts was also compared with BHA, BHT and tocopherol. Anti-oxidant activity of ethanol extracts was also examined in corn oil and lard. The ethanol extracts contents of defatted perilla flour and the original perilla seed were 7.69 and 4.56% respectively. The antioxidant activity of ethanol extracts was superior to that of 0.02% BHT, BHA and tocopherol in the perilla oil substrate, merely in concentration of one-twentieth as much as that contained in original perilla oil seeds. The fractions of non-polar solvent (hexane and chloroform) obtained from silicic acid column chromatography are less effective than that of polar solvent as an antioxidant. Antioxidant activity of partially purified ethanol fraction is slightly inferior to that of original crude ethanol extracts. Ethanol extracts were also effective in corn oil and lard almost same as in perilla oil. The total phenolic compound contents of crude ethanol extracts and partially purified ethanol fraction were 9.3, 6.4%, respectively.
