Hereinafter, the present invention will be described in more detail.

Alcohol dehydrogenase (ADH) is an enzyme belonging to the enzyme class EC 1.1.1.1 and is an enzyme that reversibly catalyzes the formation of aldehyde or ketone by dehydrogenation of alcohol. It is also capable of acting on other alcohols with a wide range of substrate specificities.

The aldehyde dehydrogenase (ALDH) can catalyze the reverse reaction as an enzyme that oxidizes an aldehyde to produce a carboxylic acid or an acyl group. Liver enzymes mainly produce acetic acid in acetaldehyde and coenzyme NAD (EC 1.2.1.3) or NADP (EC 1.2.1.4) and belong to the enzyme class EC 1.2.1.5.

Therefore, in the case of the health functional composition for protecting liver function of the present invention, the enzymatic activity of the in vivo alcohol dehydrogenase and the aldehyde dehydrogenase is increased, so that the ethanol is rapidly decomposed in the body and the hangover is eliminated.

Aspartate aminotransferase (AST) is present in the form of several isoenzymes in hepatocytes and muscle cells. When it is destroyed by various diseases, it flows out to the blood and increases. It is important to diagnose myocardial infarction and increase in liver disease. Diagnosis and treatment of liver disease and bone disease are helpful in determining the effectiveness of treatment. If a tumor develops in the bile duct or obstructs the bile duct, the cells of the bile duct are broken and the blood alkaline phosphatase is increased.

Alanine transaminase (ALT) belongs to the enzyme class EC 2.6.1.2, which is mainly present in liver and plasma. ALT is an enzyme that transfers amino group from L-alanine to α-ketoglutarate and is used as an index to diagnose the degree of liver damage.

The health functional composition comprising the acorn fermented product obtained by fermenting the 70% ethanol extract of acorn of the present invention as an active ingredient contains 0.1 to 10.0% by weight of Ellagic acid as an index component.

(Example 1) Measurement of the effect of alcohol dehydrogenase (ADH) activity

ADH activity was measured by measuring the absorbance of NADH to NADH using a UV spectrophotometer. The concentration of the sample used in the examples was 5 mg / ml.

A reaction solution consisting of 0.38 ml of 1 M Tris-hydrochloric acid buffer (pH 8.0), 0.7 ml of distilled water, 0.15 ml of 20 mM NAD, 0.15 ml of 0.2 M ethanol and 50 μl of a sample (5 mg / ml) (5 units / ml) was added, and the reaction was allowed to proceed at 25 ° C for 5 minutes. Then, an increase in absorbance was measured at 340 nm. The ADH activity was expressed as a ratio of the maximum absorbance at the end of the reaction to the maximum absorbance of the control, and was calculated by the following equation.

ADH activity = (B / A) x 100

A: maximum absorbance of the control, B: maximum absorbance of the experimental group

As shown in FIG. 1, the ADH activity in the sample was highest in the Bacillus subtilis fermented product of Sample 1, followed by the Lactobacillus plantarum fermentation product of Sample 2, and the fermentations of the other samples were low in activity.

(Example 2) Measurement of effect of aldehyde dehydrogenase (ALDH) activity

The activity of ALDH activity was measured by measuring the absorbance of NADH to NADH using a UV spectrophotometer. The concentration of the sample was 5 mg / ml.

0.15 ml of 1 M Tris-hydrochloric acid buffer solution (pH 8.0), 1.05 ml of distilled water, 50 μl of 20 mM NAD, 50 μl of 0.1 M acetaldehyde, 50 μl of 3.0 M KCl, 50 μl of 0.33 M BME and 50 μl of a sample The reaction mixture was preincubated at 25 ° C for 10 minutes, reacted at 25 ° C for 5 minutes with 50 μl of ALDH (1 Unit / ml), and the absorbance was measured at 340 nm. ALDH activity was expressed as the ratio of the maximum absorbance at the end of the reaction to the maximum absorbance of the control, and was calculated by the following equation.

ALDH activity = (B / A) x 100

A: maximum absorbance of the control, B: maximum absorbance of the experimental group

As shown in FIG. 2, the ALDH activity in the sample was highest in the Bacillus subtilis fermented product of the sample 1, followed by the Lactobacillus plantarum fermentation product of the sample 2, and the fermentation products of the other samples were low in activity. This shows test results similar to ADH activity.

(Example 3) Alcohol content In vivo measurement test

Experimental animals were divided into a test group and a control group by taking ICR mice 6 weeks old. Experimental animals were cultured for one week after purchase, and were fasted 24 hours before the experiment. The test sample was orally administered at 1,000 mg / kg, and oral administration of 0.1 ml of alcohol (40% ethanol, v / v) was administered 30 minutes later. One hour after the administration, blood was collected from the liver after anesthesia with ether and the serum was separated by centrifuge (3,000 rpm, 5 minutes) to analyze the alcohol content.

The results of measuring the content of alcohol in the blood after administering the fermented Bacillus subtilis with the highest activity of the alcohololytic enzymes to the experimental animals are shown in FIG. As shown in FIG. 3, the alcohol content of the control group to which the fermented product was not administered was 0.0515%, but the alcohol content of the test group administered with the fermented product was 0.01443%, and the blood alcohol content in the mouse was 72% lower .

(Example 4) Liver protective effect In vivo measurement test (AST, ALT, LDH)

Seven experimental animals were divided into a control group, a test group and a control test group. Experimental animals were experimented after being purified for one week after purchase. In the control group, neither acetaminophen (APAP) nor the test samples of the present invention were administered. In the test group, acetaminophen (APAP) was orally administered in DMSO at a concentration of 350 mg / kg. After 3 days, one more dose of APAP was administered. One hour after administration, the test sample was orally administered at a concentration of 1,000 mg / kg. Samples were orally administered at the same time for 6 days. In the control group, acetaminophen (APAP) was orally administered in DMSO at a concentration of 350 mg / kg. Three days later, APAP was administered once more.

After 24 hours of oral administration of the test sample, blood was collected from the liver, the test group, and the control group. The serum was separated by centrifugation (3,000 rpm, 5 minutes) ALT (SGPT) and LDH contents were analyzed.

As shown in FIG. 4, AST, ALT and LDH activities were greatly increased in the control test group that caused hepatotoxicity, but the AST activity and the ALT activity of the fermented test group were 33.8% 38.5% and LDH activity was reduced by 13.9%. This proves that the sample of the present invention has an effect of reducing the AST (SGOT), ALT (SGPT) and LDH levels in the blood, thereby improving the toxicity of the liver.

(Example 5) Identification of eragacic acid component of acorn fermented product

1 mg of the acorn fermented product using the Bacillus subtilis prepared in Preparation Example 2 was dissolved in 1 ml of methanol and used as a sample for HPLC analysis. The HPLC analysis conditions are as follows.

- HPLC: Agilent 1260 infinity

- Column: YMC triart C18 (250 mm x 4.6 mm, 5 탆, 120 Å)

- Injection volume: 5 μl

- Detection wavelength: 254 nm

- mobile phase: A- 0.1% TFA (water)

B-0.1% TFA (acetonitrile)

The obtained HPLC detection peak was compared with the detection peak of the elagancy standard solution to confirm that the maximum peak of the acorn fermentation of the present invention was elagic acid.

On the other hand, quantitative analysis of the content of ellagic acid showed that about 17.2 ± 0.13 μg of ellagic acid was present in 1 ml of the sample. Therefore, it was confirmed that the content of elastase in the acorn fermented product using the Bacillus subtilis prepared in Preparation Example 2 was about 1.7% by weight.
