Description

Technical Field [0001] The present invention relates to a composition for prevention or elimination of hangover,

The present invention relates to a method for improving the hangover effect, an ADH, an acetaldehyde dehydrogenase (ALDH) activator, and a liver protecting effect, which are produced after alcohol ingestion, or a fragrant plant extract fraction And / or a composition for relieving the hangover.

Due to frequent drinking and drinking, which is characteristic of drinking culture in Korea, many people are showing high interest in drugs or drinks that can eliminate hangovers. The hangover drink market, which is growing every year, has grown to more than 100 billion won in sales and is attracting attention from overseas market as well (Kim Hang Kyung, hangover drink market trend, Korea Food Information Service, Food World, 2009).

Hangover refers to symptoms such as headache, diarrhea, anorexia, nausea, vomiting, chills, and cold sweating that occur after drinking alcohol. Objective symptoms include cognition, decreased exercise capacity, hematologic changes, and changes in hormones. The cause of hangover is known to be dehydration, toxicity of alcohol and alcohol metabolites (acetaldehyde, formaldehyde, acetone, etc.), nutrient deficiency (blood sugar, vitamin, mineral deficiency) The degree of hangover is highly variable according to the individual's deviation, environmental condition (nutritional status, exercise status, dehydration degree, health status) according to heredity (Kwon et al., Korean Applied Pharmacology Journal, 2005, 13, 107).

Alcohol after drinking alcohol is metabolized through three pathways. When the concentration of ethanol is low, by the action of alcohol dehydrogenase and acetaldehyde dehydrogenase, which are present in the gastrointestinal tract or liver, when the concentration of ethanol is high It is metabolized to acetaldehyde and acetic acid by the microsomal ethanol oxidizing system (MEOS) present in the endoplasmic reticulum. Afterwards, the catalase activity in the peroxisome leads to carbon dioxide (CO ₂ ) And water (H ₂ O). When an appropriate amount of alcohol is introduced, the above-described metabolic system works smoothly, and the symptoms caused by alcohol do not occur. However, when a large amount of alcohol is introduced, the balance of the metabolic system is destroyed and the homeostasis can not be maintained. In the short term, Perspiration, loss of concentration, heartburn and indigestion, and liver dysfunction may occur in the long term.

The present commercial hangover beverage is composed of three components: (1) a condition (CJ) using a lotus seed, a lotus seed, a lotus seed, a rice embryo and a hinoki extract; A large number of beverages are on the market, mainly from Care (Dong-A Pharm), Duckwood, and Daehan 808 (Grammy) using Raspberry Extract.

Laosta wood ( Catalpa ovata G. Don) is also known as Japanese cypress or wood carvings. The fruit of the firewood is a medicinal substance found in the Korean Pharmacopoeia and the standard of herbal medicines, and is named as Catal (Catalpae Fructus). The other part of the tree is called confucian bacillus, and the uterus has been traditionally prescribed as diuretic for nephritis, edema, proteinuria, urinary discomfort, neuralgia, hepatitis, cholecystitis, jaundice, nephritis, pruritus and cancer . It is distributed in Korea, Japan and China.

The firewood mainly contains the ingredients of Iridoid and Naphthoquinone, which are anticancer effects (Fujiwara et al., Journal of natural products, 1998, 61, 629-632, Oh et al. (Oh et al., Planta medica, 2003), along with antioxidant activity (Moon et al., 2003, 145, 46-54) , 2002, 68, 685-689, An et al., International immunopharmacology, 2002, 2, 1173-1181, Park et al., Archives of Pharmacology Research, 2010, 33 (3), 381-385, Kim et al. , Et al., Environmental toxicology and pharmacology, 2008). In addition, there are reports of a number of studies on inflammatory bowel diseases, 2004, 10 (5), 564-572) , 26, 86-91). (Yang et al., Journal of ethnopharmacology, 2013, 145 < RTI ID = 0.0 > , 416-423).

Although a variety of physiological activities have been reported for Laaiodongae extracts and compounds isolated therefrom including the above-mentioned research reports, reports on the bioactivity of alcohol metabolizing enzymes and hangover-relieving compounds of Laaiodongae extract and fractions, Do.

The present inventors have found that the extract derived from open-hearted wood acts to quickly recover from loss of exercise capacity and sleep-inducing symptoms that occur after alcohol consumption, promotes alcohol metabolism by increasing the activity of alcohol dehydrogenase and acetaldehyde dehydrogenase, And the protective effect against liver damage due to the ingestion of acute alcohol was confirmed, thereby completing the present invention.

Thus, an example of the present invention relates to a method of producing < RTI ID = 0.0 & ovate G. Don), a dried product of the extract, and a concentrate of the extract as an active ingredient. The present invention also provides a composition for preventing and / or hanging an alcoholic hangover.

Another example of another object of the present invention is to provide fractions of Laodonga extract having optimized hangover prevention and / or hangover elimination action and a process for producing the same.

The inventors of the present invention have found that Catalpa ovate G. Don) extracts improved the exercise capacity of alcohol - treated mice, and the alcohol - induced sleep - induced symptoms were also improved. In addition, the extracts of Leiocarpaceae showed the effect of increasing the activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) in the liver tissues of mice administered with alcohol. Aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels were measured to identify liver protective effects by alleviating liver damage due to acute alcohol ingestion. Therefore, the inventors of the present invention have confirmed that the fragrant product obtained from the extract of Laodonga extract or Laodomai extract can be effectively used for the prevention of alcoholic hangover and / or for the removal of hangover based on the above-described experimental results, and thus the present invention has been completed .
