In vitro biological activities of ethanol extract of radish including whitening, hangover removal, antimicrobial and antioxidant activities were analyzed. For whitening activity assay, tyrosinase inhibition rate was measured as $IC_{50}$ (50% inhibitory concentration). The $IC_{50}$ values of radish trunk and root extracts were estimated as 0,9 mg/ml and 2.1 mg/ml, respectively. Radish trunk extract showed 2.5-fold tyrosinase inhibition activity of radish root extract, however, there was no significant difference according to radish species. By alcohol dehydrogenase (ADH) activity assay as a hangover removal activity assay, radish trunk extract (2.5 mg/ml) and root extracts (8 mg/ml) showed ]50% activation of ADH. TBA values of radish trunk and root extracts (1% of each) were 43-61 % level of ${\alpha}-tochoperol$ (2.2%). From the analysis of in vitro biological activities of radish, it was suggested that radish could be used in functional food or cosmetics containing hangover removal, whitening and antioxidant activities.

Perismmon has been consumed for long times in Korea and used as a drug for a long time in Korea, It was known to help alcohol intoxication. Ingested alcohol is metabilized by alcohol dehydrogenease and acetaldehyde dehydrogenase in liver. Alcohol dehydrogenease activator and acetaldehyde dehydrogenase activator(ALDHA) was detercted in persimmon. The oncentration of ALDHA was determined and compared in different havesting time, species, and available processed foods. The level of ALDHA was highest in persimmon (Fuyu) harvested in November. Lower ALDHA activities were found in its processed foods. Persimmon and its processed foods are expected to be effective in decreasing the concentration of alcohol and acetaldehyde after alcohol intake.

The antioxidant and alcohol-degrading enzyme activities of soybean sprout sugar solutions (oligosaccharide and sucrose, $50^{\circ}Bx$) were characterized under different soaking conditions. The ratio of sugar solution to sprout content was 25%, 50%, and 75% (w/w), and the soaking times studied were 1, 3, 6, 12, and 24 h. Higher 1,1-diphenyl-2-pycrylhydrazyl (DPPH) radical-scavenging activity was detected in case of the oligosaccharide solution, compared to the sucrose solution. A similar tendency was observed for alcohol-degrading enzyme activity. When the ratio of sugar solution to sprout content was 50% (w/w), the total phenol and flavonoid contents were found to be higher, compared to those observed at 20% (w/w). However, we did not observe a significant difference between 50% and 75% (w/w). Soaking time did not significantly affect the antioxidant and alcohol-degrading enzyme activities of the solutions. As a result, when oligosaccharide solution was used for soaking soy sprouts at a ratio of >50% (w/w), higher antioxidant and alcoholdegrading enzyme activities were observed.

Ginsenosides are major constituents of ginseng and are known to be responsible for its pharmacological properties. This study aimed to investigate the detoxification effect of a mixture containing black red ginseng powder, red ginseng extract, Puerariae radix extract, and Hovenia dulcis extract, on SD (Sprague Dawley) rats treated with 30% ethanol. Thirty minutes before treatment, the animals were orally administered different concentrations of the mixture or water. Results revealed that the concentration of ethanol in blood serum was significantly decreased in the black red ginseng mixture treated group in a dose-dependent manner, as compared with that of the control group. The blood level of acetaldehyde increased until 1 hr after alcohol administration, but the levels rapidly decreased later. Furthermore, ADH and ALDH activities in the hepatic tissue were also increased in the black red ginseng mixture administered group, than in the control group. These results indicate that the black red ginseng mixture has the ability of decomposing alcohol by increasing the ADH and ALDH activities responsible for alcohol metabolism.

To investigate the anti-hangover effects of Cudrania tricuspidata root extract (CTE), the blood alcohol metabolism and blood gas imbalance of CTE in rats treated with 10 ml/kg alcohol were examined. CTE (500 mg/kg and 750 mg/kg) was administrated after 30 minutes of alcohol consumption (10 ml/kg). Blood collection was implemented from the tails of the animals after 1, 3, and 5 hours post alcohol consumption. The Condition drink (a commercial anti-hangover beverage) was used as a positive control. Single administration by the oral route was performed. The consumption of CTE (500 mg/kg and 750 mg/kg) decreased the serum alcohol concentration by increasing and maintaining both the alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) enzyme activity levels in the blood and liver. In addition, CTE led to recovery from the imbalances in the blood gas levels, including carbon dioxide ($CO_2$) and changes in pH, bicarbonate ($HCO_3{^-}$) and lactic acid levels due to alcohol ingestion. In conclusion, CTE exerted a more pronounced anti-hangover effect than a commercial anti-hangover drink. Therefore, CTE can be a novel and safe anti-hangover natural product agent for the prevention or treatment of symptoms caused by excessive alcohol consumption.

This study was conducted to investigate the detoxification effect of extract from soy-sprout grown using high concentrated oxygen water extract (SE) against alcohol-induced hangover in male Sprague-Dawley (SD) rats. The rats were orally administered with different concentrations of SE beverage [26, 260 and 2,000 mg/kg body weight (b.w.)] and, after 30 min, with alcohol at a dose of 3 g/kg b.w. After 1 and 3 h of alcohol administration, blood was collected from the retro-orbital plexus, while after 5 h, blood was collected from the heart. In the 2,000 mg/kg b.w. SE group, the concentration of blood alcohol was significantly reduced after 1-5 h of alcohol loading as compared with that in the other groups. In addition, the blood acetaldehyde concentration was reduced by SE (2,000 mg/kg b.w.). These results suggest that SE beverage can alleviate alcohol hangover symptoms by stimulating the activities related to hepatic alcohol-metabolizing enzymes.

To develop an effective anti-hangover product, hot-water extracts of 25 medicinal herbs were screened for inhibition or activation of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH), and 12 herbs were selected for further study. Chosen medicinal herb extracts(CMHEs) were fermented by Lactobacillus delbruechii subspecies lactis for 10 days at $35^{\circ}C$ after saccharification with nuruk(malt inoculated by 5 types of microbs) for 72 hours at $35^{\circ}C$ and both CMHEs and fermented CMHEs(FCMHEs) were explored for anti-hangover effects in vitro. We found significant ADH inhibition by hot-water extracts of Pueraria thunbergiana, Hovenia dulcis Thunb, Lycium chinense, Glycyrrhiza uralensis, Acanthopanax sessiliflorus, Liriope platyphylla, and Ixeris dentata, and significant ALDH activation by extracts of Acanthopanax sessiliflorus, Lycium chinense, Ixeris dentata, and Polypori umbellati of the Polyporaceae. The ADH effects on CMHE and FCMHE were -20.22% and -62.63% of control values, and the ALDH effects 173.20% and 280.17%, respectively. In rats given 20%(v/v) alcohol(15 mL/kg), FCMHEs significantly decreased blood acetaldehyde concentrations on 3 hours after ethanol administration, in a dose-dependent manner(p<0.05). Notably, blood acetaldehyde concentrations were markedly reduced in animals given FCMHEs(400 mg/kg) compared to levels seen in rats receiving CADB(commercial alcohol detoxification beverage). Thus, anti-hangover effects were promoted by fermentation of certain medicinal herb extracts.

We investigated the physiological activity and solvent-partitioned fractions of methanol extracts from the green seaweed Sargassum fulvellum. The methanol extract from S. fulvellum was sequentially fractionated with n-hexane (SFMH), methanol (SFMM), buthanol (SFMB), and water (SFMA). We investigated the antioxidant activities of solvent fractions from S. fulvellum by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging capacity and an SOD activity assay. DPPH radical scavenging capacity of SFMM was 79.5% at 10 mg/ml. SOD activity of SFMM was 79.9% at 10 mg/ml. Nitrite scavenging activities of solvent fractions from S. fulvellum were investigated under different pH conditions and showed the most remarkable effect at pH 1.2. In particular, the activity of SFMB was higher than the other fractions. ADH activity and ALDH activity of SFMM were 177.0% and 167.4% at 10 mg/ml, respectively. ${\alpha}$-Glucosidase inhibitory activity of SFMH increased in a dose-dependent manner and was about 94.1% at 2 mg/ml. Elastase inhibitory activity was 93.2% at 2 mg/ml. These results revealed that S. fulvellum extracts have strong antioxidant and alcohol dehydrogenase activities and ${\alpha}$-glucosidase inhibitory activity, suggesting that S. fulvellum extracts have potential as a source of natural products for health and beauty.

This study was performed to investigate the ameliorating effect of a mixture of extracts from Houttuynia cordata Thunb, Nelumbo nucifera G. (leaf), and Camellia sinensis (seed) (MIX) on acute ethanol-induced hangover in Sprague-Dawley rats. Plasma ethanol and acetaldehyde levels in MIX-treated rats significantly decreased at 3 h and 5 h after acute ethanol administration (25%, 3 g/kg body weight/d) as compared to ethanol-treated rats. Hepatic alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities were significantly higher in MIX-treated rats than in ethanol-treated rats. MIX exhibited high ADH and ALDH activities on direct assays using S9 rat liver fraction for ethanol metabolic enzymes clearance action. These results suggest that MIX could alleviate ethanol-induced hangover symptoms by elevating activities related to hepatic ethanol-metabolizing enzymes against ethanol induced metabolites, and MIX should be further developed to be a new anti-hangover material.
