The present invention relates to a composition containing Dolichos lablab Linn. extract as an active ingredient for easing hangovers, and preventing, alleviating or treating alcoholic gastrointestinal diseases.
If you drink alcohol until you are drunk, you may experience the toxicity of alcohol and its intermediate metabolite, acetaldehyde, dehydration, nutrient deficiencies (blood sugar, mineral, and vitamin deficiencies) due to malabsorption, etc. The symptoms greatly vary depending on the individual differences (genetic inheritance), environmental conditions (nutritional status, exercise status, degree of dehydration, health status, etc.).
Alcohol is oxidized to acetaldehyde in the liver by alcohol dehydrogenase (ADH) and the coenzyme NAD+, and acetaldehyde is degraded into acetic acid by aldehyde dehydrogenase (ALDH) and NAD+. Alcohol is also oxidized to acetaldehyde by cytochrome P-450 type 2E1 (CYP2E1) and catalase. It is known that acetaldehyde and acetic acid cause lipid peroxidation, etc., which lead to cytotoxicity, headache or abdominal pain, dehydration resulting from osmotic pressure changes, etc. In addition, excessive alcohol consumption may cause gastrointestinal diseases, and in severe cases, it may cause gastritis or gastric ulcer. Frequent consumption of alcohol in addition to social stress is often accompanied by severe gastric ulcer and liver diseases. Thus, many medicines and healthy functional foods are on the market to alleviate them. Research efforts have been mainly focused on activating ADH and ALDH and thereby lowering the blood alcohol concentration. However, there are few studies on the promotion of degradation of the alcohol ingested due to alcohol consumption or the alleviation of the resultant gastrointestinal diseases.
Dolichos lablab Linn., which is also called lablab bean, Egyptian bean or kidney bean, has alternate, compound, trifoliate leaves. The stipules are small and triangular, and the leaflets are broadly ovate and acute. The leaves on the stems have a wide wedge or block shape with flat edges and are thinly hairy on both sides. The flowers are butterfly-shaped and white. The seeds are white and there are 2 to 5 seeds in each pod.

The present invention relates to a healthy functional food composition containing Dolichos lablab Linn. extract as an active ingredient for easing hangovers, and preventing or alleviating alcoholic gastrointestinal diseases.
As used herein, the hangover is a phenomenon caused by accumulation of alcohol or acetaldehyde in the body due to lack of alcohol dehydrogenase (ADH), which degrades alcohol, or aldehyde dehydrogenase (ALDH), which degrades acetaldehyde, in a drunken state. Representative symptoms of hangover include nausea, dizziness, vomiting, thirst, lethargy, headache, myalgia, indigestion, abdominal pain, and diarrhea.
The alcoholic gastrointestinal diseases are preferably nausea, vomiting, abdominal pain, indigestion, alcoholic gastritis or alcoholic gastric ulcer, although not limited thereto. The Dolichos lablab Linn. extract can promote the degradation of alcohol and acetaldehyde in the blood and increase aldehyde dehydrogenase activity.
Conventional extraction solvents known in the art may be used for the Dolichos lablab Linn. extract. Preferred extraction solvents are water, C1-C4 anhydrous or hydrated lower alcohols (e.g., methanol, ethanol, propanol, butanol, n-propanol, isopropanol and n-butanol), a mixed solvent of the lower alcohol and water, acetone, ethyl acetate, chloroform, 1,3-butylene glycol, hexane, diethyl ether, or butyl acetate, more preferably water, ethanol or a mixed solvent thereof, still more preferably water. In the case of hot water extraction using water, water was added in an amount 5 to 10 times by volume relative to the weight of Dolichos lablab Linn. and heated at 90 to 110° C. for 2 to 3 hours to perform extraction. Preferably, the extracted solution is filtered through a filter paper and then lyophilized for use, although not limited thereto. In the case of ethanol extraction, 80% ethanol was added in an amount 5 to 10 times by volume relative to the weight of Dolichos lablab Linn, and the Dolichos lablab Linn was immersed at a room temperature of 20 to 25° C. for 22 to 24 hours to perform extraction.

(1) Preparation of a Hot Water Extract of Dolichos lablab Linn.
2 L of water was added to 200 g of Dolichos lablab Linn., followed by heating at 90 to 100° C. for 2 to 3 hours. The extract was then filtered and then dried under reduced pressure using a lyophilizer to obtain a hot water extract of Dolichos lablab Linn. The extract was dissolved in sterilized water for use in experiments.
(2) Preparation of an ethanol extract of Dolichos lablab Linn.
2 L of 80% ethanol was added to 200 g of Dolichos lablab Linn., followed by immersion at a room temperature of 20 to 25 for 22° C. to 24 hours. The extract was then filtered, concentrated with a vacuum concentrator, and then dried under reduced pressure using a lyophilizer to obtain an ethanol extract of Dolichos lablab Linn. The extract was dissolved in sterilized water for use in experiments.
In Example 2, the effect of the hot water extract of Dolichos lablab Linn. of the present invention on the blood ethanol concentration increased by ethanol consumption was determined.
6-week-old (n=5) male SD rats were divided into three groups. The first group was a control group not subjected to any treatment, and the second group was an ethanol-administered group (alcohol+vehicle) which was administered with 20% (v/v) ethanol for 2 days and with 40% (v/v) ethanol on the third day. The third group was a Dolichos lablab Linn. extract-administered group which was pretreated with 400 mg/kg of Dolichos lablab Linn. extract for 3 days prior to administration of ethanol, and then administered with 400 mg/kg of Dolichos lablab Linn. extract 30 minutes prior to administration of ethanol. The blood collected from the orbital and the blood collected from the abdominal vena cava 30 minutes, 60 minutes, 120 minutes and 180 minutes after the last administration of ethanol and the Dolichos lablab Linn. extract was centrifuged at 3000 rpm for 20 minutes. The concentration of ethanol contained in the thus-obtained serum was measured with an ethanol measuring kit (Abcam, ab65343).
As a result, as shown in
The ALDH activity and ADH content were measured using the serum obtained in Example 2 above. The ALDH activity was measured using an aldehyde dehydrogenase activity colorimetric assay kit (BioVision), and ADH was measured using an aldehyde quantification assay kit.
As a result, as shown in
The blood acetaldehyde concentration of the ethanol-administered group continuously increased for 3 hours. However, the concentration in the group administered with the hot water extract of Dolichos lablab Linn of the present invention was maintained at a level almost similar to that of the normal group (
After the blood was collected in Example 2, the animal models were sacrificed and the stomach and liver tissues were stained with H&E to determine whether there was gastrointestinal and liver damage caused by ethanol consumption, and whether the hot water extract of Dolichos lablab Linn. of the present invention alleviated gastrointestinal and liver damage.
As a result, as can be seen in the staining pictures of the gastrointestinal tissues in
As shown in
Meanwhile, the effect of Dolichos lablab Linn extract could not be determined from the liver tissue staining results as shown in
