Description

Composition for improvementing, preventing or treating leaky gut syndrome comprising fractions or extract of pepper leave}

The present invention relates to a composition for improving, preventing or treating inflammatory bowel disease or leaky gut syndrome, and is useful in functional foods and drugs for preventing, improving or treating inflammatory bowel disease or leaky gut syndrome by containing red pepper leaf extract as an active ingredient. Can be used.

In addition to the basic functions of digestion, absorption, and excretion of food, the intestinal tract of the human body performs an immunological function as a barrier to the intestinal mucosa blocking the inflow of microorganisms, their by-products, antigens, and toxins into the bloodstream. That is, the merit film is a barrier that blocks foreign substances and has a dual function of passing and absorbing them.

Intestinal health is very important because if there is a problem with these intestinal functions, not only does it cause problems in the supply of nutrients to the human body by itself, and symptoms such as repetitive constipation, diarrhea, and abdominal pain greatly interfere with daily life.

Inflammatory bowel disease is a disease in which the intestine is chronically inflamed, and the cause of the disease and the cure method are not yet known. In general, it refers to Crohn's disease and ulcerative colitis. Crohn's disease and ulcerative colitis may show symptoms such as diarrhea, abdominal pain, nausea, fever, loss of appetite, weight loss, and fatigue. Crohn's disease occurs mainly in the small and large intestine, but ulcerative colitis is invented only in the large intestine. In addition to this, long-sized Behcet's disease, which is relatively common in Korea, also belongs to this.

Drugs used to treat such inflammatory bowel disease include steroidal immunosuppressants, 5-aminosalicylic acid (5-ASA) drugs that block the production of prostaglandins (e.g., sulfasalazine), Mesalazine and the like are being used, and they cause serious side effects such as fullness, headache, rash, liver disease, leukopenia, agranulocytosis and male infertility, as well as having insignificant therapeutic effect on inflammatory bowel disease. Its use is restricted.

Therefore, if it is possible to develop a therapeutic agent for inflammatory bowel disease that does not cause side effects, it is expected that it will be possible to treat patients with inflammatory bowel disease more safely and effectively, but a therapeutic agent without side effects has not been developed yet.

Under this background, the present inventors have made diligent efforts to develop a therapeutic agent for inflammatory bowel disease derived from natural products that do not cause side effects, and as a result, a composition containing red pepper leaf extract is effective in treating not only inflammatory bowel disease but also intestinal leak syndrome, The present invention was completed by confirming that it enhances the intestinal immune function.

Hereinafter, the present invention will be described in detail.

The present invention relates to a composition for improving, preventing or treating inflammatory bowel disease or leaky intestinal syndrome, using red pepper leaf extract as an active ingredient.

Pepper ( Capsicum annuum ) is a tropical plant, classified as an annual plant belonging to the Solanaceae family , and is one of the most consumed vegetables worldwide. In Korea, it is cultivated mainly from late spring to summer, and has been used as a food ingredient for a long time as the main ingredient of kimchi. Currently, there are about 20 to 30 varieties of peppers known worldwide, of which Capsicum annuum, Capsicum frutescens, Capsicum chinense, Capsicum baccatum, and Capsicum pubescens are the most cultivated. Red pepper is not only rich in vitamins and minerals, but it is reported that it contains a large amount of phenolic compounds such as carotenoid, quercetin, luteolin and capsaicinoids, but studies on red pepper leaves are insufficient.

In the present invention,'leaky gut syndrome' or'leaky gut syndrome'; LGS' refers to a phenomenon in which intestinal membrane cells maintain a certain gap between cells, and during the process of digestion and absorption, any stimulation or damage is applied, thereby increasing the permeability of the intestinal membrane in which a polymer material can reciprocate through the gap between cells. It collectively refers to symptoms caused by a phenomenon in which a polymer material in the blood leaks into the intestinal lumen due to a failure to function properly in the intestine or a phenomenon in which a polymer material in the lumen directly enters the blood (leaky gut). These symptoms appear in various clinical conditions such as aging, allergies, multiple trauma, rheumatoid arthritis, inflammatory bowel disease, chronic fatigue syndrome, and irritable syndrome. In addition, pathogens, antigens, and decay substances are introduced into the intestinal mucosa due to increased permeability of the intestinal mucosa or damage to the intestinal mucosa, leading to inflammatory reactions, and endotoxins flowing into the bloodstream, resulting in bacterial translocation and intestinal endotoxemia. It causes various inflammatory reactions and immune reactions.

Such leaky gut syndrome complains of various, extensive, and ambiguous symptoms without specific symptoms. Specifically, it has a peculiarity in that it has symptoms that complain in common in various diseases.

The exact cause of the leaky gut syndrome has not been identified, but the use of non-steroidal antiin ammatory drugs (NSAIDs) used as pain relievers for a long time, antibiotics and steroids, anticancer chemistry as an anticancer therapy In the case of receiving therapy or radiation therapy, when a change in the composition of the normal intestinal flora occurs, the reproduction of fungi in the intestine, ingestion of excessive food, ingestion of spoiled food or ingestion of heavy metals or toxic substances, excessively irritating food Ingestion or hypersensitivity to certain foods, excessive use of alcohol, multiple trauma, exposure to acute chronic mental stress, chronic intestinal bacteria, parasites, and yeast infections can be cited.

Specifically, the composition for improving, preventing or treating leaky gut syndrome may be referred to as a composition for improving, preventing, alleviating, suppressing and treating that the permeability of the intestine is increased due to the various causes. This has the effect of improving, preventing, and treating intestinal leak syndrome, which causes various diseases, as high intestinal permeability increases, so that polymeric substances in the blood leak into the intestinal lumen, or polymeric substances in the lumen enter the branched blood. The improvement, prevention, or treatment of leaky gut syndrome may mean suppressing a phenomenon in which the intestinal membrane cell gap is loosened and thus the permeability of the intestinal membrane through which a polymer material can reciprocate increases.

The inflammatory bowel disease may be a disease selected from the group consisting of Crohn's disease, ulcerative colitis, enteric Behcet's disease, infectious enteritis, ischemic bowel disease, and radiation enteritis.

According to the experimental results of the present invention, it can be seen that when a high-fat diet is administered for a long time, inflammatory factors such as cytokine IL-6 are increased, and the activation of inflammatory cells is increased. This induces inflammation in the intestine over time, and soon enteritis is induced.

At this time, it can be seen that when the red pepper leaf extract is co-administered, immune activity is increased, inflammatory response is suppressed, and activation of inflammatory cells is reduced. Therefore, it can be seen that the composition comprising the red pepper leaf extract according to the present invention as an active ingredient has an effect of improving, preventing or treating inflammatory bowel disease.

The red pepper leaf extract is more specifically characterized in that it enhances IgA expression and inhibits or reduces the expression _{of IL-6 and LTB 4.}

In the present invention, the'extract' includes not only the crude extract obtained by treating the extraction raw material with the extraction solvent, but also the processed product of the crude extract. For example, the red pepper leaf extract may be prepared in a powder state by additional processes such as distillation under reduced pressure and freeze drying or spray drying.

In addition, the'extract' in the present invention also includes a fraction obtained by further fractionating the crude extract. That is, the red pepper leaf extract includes not only those obtained by using an extraction solvent, but also those obtained by additionally applying a purification process thereto. For example, a polymer fraction obtained by passing through an ultrafiltration membrane having a certain molecular weight cut-off value, separation by various chromatography (made for separation according to size, charge, hydrophobicity or affinity), etc. It can be purified through a method.

The polymer fraction may preferably be a fraction obtained by separating only a polymer material having a molecular weight of 10 kDa or more after obtaining a red pepper leaf extract or a red pepper leaf extract using an extraction solvent.

In addition, in the present invention, the'pepper leaf extract' is an extract of the red pepper leaf using water, an alcohol having 1 to 4 carbon atoms, or a mixed solvent thereof, and the extraction method does not need to be particularly limited. Preferably, the red pepper leaf extract may be a hot water extract of red pepper leaf or an ethanol solution of red pepper leaf, and may be, for example, a red pepper leaf alcohol extract. Most preferably, it may be a hot water extract of red pepper leaves.

In addition, the red pepper leaf extract may be processed by the red pepper leaf extract, and then repeatedly extracted one or more times with water, alcohol having 1 to 4 carbon atoms, or a mixed solvent thereof.

The red pepper leaves may be cut into a certain size, dried using a shade or a dryer, and then crushed or used as it is. The drying period is not particularly limited as long as the moisture content in the red pepper leaves is less than 20%.

Compared to other parts of pepper, using pepper leaves increases IgA expression when administered on a high-fat diet for a long period of time _{, inhibits or reduces IL-6 expression and LTB 4} expression, and is 1.5 to 2.5 times higher in effect, and intestinal permeability. Since it is also suppressed by 2 to 5 times or more, red pepper leaf extract is remarkably excellent in preventing, improving, or treating inflammatory bowel disease as well as intestinal leak syndrome compared to other parts of pepper.

In the present invention, the term "contained as an active ingredient" or "contained as an active ingredient" means including an amount sufficient to improve, prevent or treat inflammatory bowel disease or leaky intestinal syndrome of the red pepper leaf extract of the present invention. Since the red pepper leaf extract is a natural product and does not have side effects on the human body even if it is administered in an excessive amount, the upper and lower limits of the quantity of the red pepper leaf extract included in the composition of the present invention can be selected and carried out by a person skilled in the art within an appropriate range.

In the present invention, when the composition containing the red pepper leaf extract as an active ingredient is treated, the composition enhances IgA expression when administered on a high fat diet for a long period of time, and inhibits or reduces the expression _{of IL-6 and LTB 4,} It was confirmed that there is an effect of preventing, improving or treating inflammatory bowel disease, and it was confirmed that it has an effect of inhibiting and reducing intestinal permeability.

<Test Example>

Test Example 1. Analysis of yield, sugar and protein content of hot water extract of red pepper leaf of Example 1 and polymer fraction of red pepper leaf of Example 2

For the analysis of neutral sugars, the method of Albersheim et al. was partially modified to derivatize each constituent sugar with alditol acetate and aldonolactone after hydrolysis, and GC (Gas Chromatography ACME-6100, Young-Lin Co. Ltd. Anyang, Korea) ) Was used. The sample of Example 1 or 2 was hydrolyzed by reacting for 1.5 hr at 121° C. in 2 M TFA (trifluroacetic acid), and then dissolved in 1 ml of 1 M NH ₄ OH (ammonia solution) and 10 mg of NaBH ₄ It was reduced by 4 hr. After adding an appropriate amount of acetic acid to _{remove the remaining NaBH 4} , methanol was added thereto and repeated drying to remove excess acetic acid and converted to alditol. 1 ml of acetic anhydride was added to the alditol and reacted at 121° C. for 30 min to convert to alditol acetate, which was _{separated and extracted with a chloroform/H 2} O two-phase solvent system. After drying, the extract was dissolved in a small amount of acetone and used as a sample for GC analysis.

Protein quantification was measured according to the Bradford method, and BSA (Bovine Serum Albumin, sigma aldrich) was used as a standard and diluted at a constant multiple with 1 mg/ml as the highest concentration. After adding 20 µl of each standard and sample to 980 µl of Bradford reagent, the absorbance was measured at 595 nm using a microplate reader. Protein quantification was converted into an amount for BSA.

Total sugar was measured according to the phenol-sulfuric acid method, and after stirring the same amount of 5% phenol solution to 0.5 mL of the sample solution, 2.5 mL of concentrated sulfuric acid (98%, v/v) was added and reacted at room temperature for 20 minutes to make a microplate. Absorbance was measured at 470 nm using a reader. For the determination of total sugar, a calibration curve was prepared using a glucose standard (sigma aldrich) and converted into the amount.

The total polyphenol content was analyzed according to the Folin Denis method using gallic acid (sigma aldrich).

In the case of constituent sugar, the oligosaccharides of the sample were hydrolyzed to monosaccharides, and then HPAEC-PAD (high-performance anion-exchange chromatography-pulsed amperometric detector) was used, and the data were analyzed using Chromelon 6.80 software (Dionex). Monosaccharides (fucose, rhamnose, arabinose, galactose, glucose, xylose) were used as standard solutions.

As a result, as a result of analyzing the physicochemical properties such as the content of main components of the hot water extract and the polymer fraction from red pepper leaves, it is shown in Table 1 below.

* The content ratio (%) of the chemical component represents the weight% in the dry sample.

As shown in Table 1, the hot water extract of red pepper leaves prepared from Example 1 was found to have a yield of 12.66%, a protein content of 4.5% by weight, and a neutral sugar content of 70.7% by weight, indicating a high sugar content. In addition, as a result of analyzing the constituent sugars of the hot water extract of red pepper leaves prepared in Example 1, the main constituent sugar was glucose (54.8 Mole%), and galacturonic acid, rhamnose, and galactose were contained in 11.1, 9.3, and 8.5 Mole%, respectively. , arabionose, mannose, and xylose were found to be present in trace amounts of 2.5, 0.8, 0.6 Mole%, respectively.

On the other hand, the yield of the red pepper leaf polymer fraction prepared from Example 2 was found to be as low as 2.68%, but it was confirmed that the protein content was 4.3% by weight, the neutral sugar content was 52.4% by weight, and the uronic acid was 36.7% by weight. In addition, in the red pepper leaf polymer fraction prepared from Example 2, the constituent sugar content of galacturonic acid and glucose was detected as 36.0 and 34.6 Mole%, respectively, and galactose, arabinose, rhamnose, glucuronic acid, mannose, xylose, and fucose were 7.1, 4.9, respectively. It was confirmed that there were trace amounts of 3.6, 1.5, 0.8, 0.6, and 0.2 Mole %. It was confirmed that the sugar content of the red pepper leaf polymer fraction (HEPL) of Example 2 was reduced as a whole compared to the hot water extract of red pepper leaf of Example 1, but the contents of Arabinose, Fucose, and Glucuronic acid slightly increased. That is, it can be seen that there is a clear difference between the specific components present in the two extracts.

Test Example 2. Analysis of Factors Related to Inflammation of Hot Water Extract of Red Pepper Leaf of Example 1

1) Experimental animals

First, 45 6-week-old male C57BL/6J mice were purchased through a central laboratory animal. The experimental animals were divided into five groups as follows. Nine experimental animals were used for each group, and after 8 weeks of diet, the intestinal immune modulating efficacy was evaluated.

-Normal feed group (NC): An experimental group fed with normal feed (AIN-93G) and administered only the vehicle orally

-High fat diet group (HFD): Experimental group that fed high fat (60% kcal fat) feed and administered only vehicle orally

-Positive control group (GC): An experimental group fed with a high-fat feed and orally administered 50 mg/kg of garcinia cambogia extract

-Experimental group 1 (WEPL50): an experimental group in which 50 mg/kg of hot water extract of red pepper leaves prepared in Example 1 was orally administered after feeding a high-fat feed

-Experimental group (WEPL100): A high-fat feed was fed, and 100 mg/kg of hot water extract of red pepper leaves prepared in Example 1 was administered orally.

At this time, a modified AIN 76A purified rodent diet (60 cal% fat) was used as a high fat diet, which increased calorie by 60 cal% by adding Lard.

2) analysis

After the 8-week diet period was over, the experimental animals of each group were fasted from 6 hours before analysis. Next, the experimental animals were anesthetized and the abdomen was opened. After collecting blood from the inferior vena cava using a sterile syringe, it was stored in a sterile tube treated with heparin. The obtained blood was centrifuged (12,000 × g, 10 minutes, 4° C.), and the supernatant was taken and used for analysis. The concentrations of immunoglobulin A, IL-6, and leukotriene B4 in blood were determined using Mouse IgA ELISA kit (Abcam, ab157717), Mouse IL-6 Quantikine ELISA kit (R&D systems, M6000B), LTB4 Parameter Assay Kit (R&D systems, KGE006B), respectively. Quantified.

As shown in FIG. 1, in the normal feed group (NC), the blood IgA concentration was 16.25 µg/ml, but in the positive control group (GC), it was confirmed that the intestinal immunity activity was increased to 26.17 µg/ml. In the first experimental group in which the hot water extract of red pepper leaves prepared in Example 1 was orally administered at a concentration of 50 mg/kg, 25.52 µg/ml of IgA was confirmed. In addition, 30.91 µg/ml IgA was detected in the second experimental group in which the hot water extract of red pepper leaves prepared in Example 1 was orally administered at a concentration of 100 mg/kg.

Taken together, it can be seen that the hot water extract of red pepper leaves of Example 1 also enhances intestinal immune activity like the positive control (GC). In particular, it was confirmed that the intestinal immunity activity was also increased as the dose concentration of the hot water extract of red pepper leaves (Example 1) increased, and it was found that the hot water extract of red pepper leaves according to the present invention has the effect of reducing inflammation by enhancing intestinal immunity. I can.

Figure 2 is by measuring the expression level of the cytokine IL-6 in serum for the normal feed group (NC), high fat diet group (HF), positive control group (GC), the first experimental group (WEPL50), and the second experimental group (WEPL100). This is the graph shown.

IL-6 is a representative cytokine known to be increased in inflammatory bowel disease. In the present invention, while inducing inflammatory bowel disease through a long-term high-fat diet for 8 weeks, the hot water extract of red pepper leaves of Example 1 was mixed and administered to investigate the effect of preventing or treating inflammatory bowel disease. As shown in Figure 2, it can be seen that the concentration of IL-6 was significantly increased to 12.37 pg/ml in the high fat diet group (HF) in which inflammatory bowel disease was induced through a high fat diet for 8 weeks. In the case of the first and second experimental groups in which the high-fat diet and hot water extract of red pepper leaf of Example 1 were co-administered at various concentrations, 1.78 pg/ml and 1.96 pg/ml of IL-6 were detected, respectively. This is lower than the concentration of IL-6 (2.89 pg/ml) in the positive control group (GC), which was co-administered with Garcinia cambogia extract, which is known to have a therapeutic effect on inflammatory bowel disease, and lower than that of the normal feed group (NC) (2.78 pg/ml). It's a shame. That is, it can be seen that the hot water extract of red pepper leaves prepared in Example 1 significantly inhibits IL-6 production than the normal feed group or garcinia cambogia extract. Through this, it can be seen that the hot water extract of red pepper leaves according to the present invention has an improvement, prevention or treatment effect for inflammatory bowel disease by suppressing the inflammatory reaction in the intestine. Garcinia cambogia is known to accompany various side effects such as dry mouth, dizziness, headache or diarrhea when ingested. It has a great advantage in that it is a stable substance with no toxicity detected.

Figure 3 is a normal feed group (NC), high fat diet group (HF), positive control group (GC), the first experimental group (WEPL50) and the second experimental group (WEPL100) in serum cytokine leukotriene B4 (LTB ₄ ) expression amount It is a graph showing by measuring.

leukotriene B4 (LTB ₄ ) is known to be involved in the activity of inflammatory cells by inducing an inflammatory response in immune cells. Therefore, the level of inflammation was analyzed by measuring the _{LTB 4} concentration from experimental animals in which inflammatory bowel disease was induced by a long-term high fat diet. As shown in FIG. 3, when inflammatory bowel disease was induced through a high-fat diet, _{it can be seen that the concentration of LTB 4} was significantly increased to 1357 pg/ml compared to the normal feed group (NC). _{On the other hand, it was confirmed that the LTB 4} concentration decreased to 976 pg/ml in the positive control group (GC) in which garcinia cambogia extract was administered concurrently with a high fat diet.

_{It was also confirmed that the concentration of LTB 4} decreased to 1177 pg/ml and 1026 pg/ml, respectively, in the first and second experimental groups, in which the hot water extract of red pepper leaf prepared in Example 1 was administered in parallel with a high fat diet.

In addition, the hot water extract of red pepper leaves according to the present invention _{showed a decrease in the concentration of LTB 4} similar to that of the positive control group and the normal feed group, through which it can be seen that it has an effect of inhibiting _{LTB 4} production equivalent to that of the garcinia cambogia extract.

Although the 1st and 2nd experiment groups to which hot water extract of red pepper leaves were administered had less _{decrease in LTB 4} concentration than the positive control group, there is a problem that various side effects may occur in the case of the Garcinia cambogia extract, whereas the hot water extract of red pepper leaves of the present invention is very As a stable substance, it can be seen that it has a remarkably excellent effect in that it exhibits a remarkable anti-inflammatory effect without showing any cytotoxicity.

It was confirmed that the hot water extract of red pepper leaf according to the present invention can exhibit an effect in improving, preventing or treating inflammatory bowel disease by inhibiting the activity of inflammatory cells. Furthermore _{, in order to obtain a remarkable activity of inhibiting LTB 4} production at the level of a normal feed group, the hot water extract of pepper leaves is preferably administered at a concentration of 100 mg/ml.

Test Example 3. Effect of hot water extract of red pepper leaves on improving, preventing or treating leaky gut syndrome

1) Experimental animals

First, 45 6-week-old male C57BL/6J mice were purchased through a central laboratory animal. The experimental animals were divided into five groups as follows. Nine experimental animals were used for each group, and after 8 weeks of diet, the efficacy of improvement, prevention and treatment for intestinal leak syndrome were evaluated.

-Normal feed group (NC): An experimental group fed with normal feed (AIN-93G) and administered only the vehicle orally

-High fat diet group (HFD): Experimental group that fed high fat (60% kcal fat) feed and administered only vehicle orally

-Positive control group (GC): An experimental group fed with a high-fat feed and orally administered 50 mg/kg of garcinia cambogia extract

-Experimental group 1 (WEPL50): an experimental group in which 50 mg/kg of hot water extract of red pepper leaves prepared in Example 1 was orally administered after feeding a high-fat feed

-2nd experimental group (WEPL100): A high-fat feed was fed, and 100 mg/kg of hot water extract of red pepper leaves prepared in Example 1 was administered orally.

At this time, a modified AIN 76A purified rodent diet (60 cal% fat) was used as a high fat diet, which increased calorie by 60 cal% by adding Lard.

2) analysis

After the 8-week diet period was over, the experimental animals of each group were fasted from 6 hours before analysis. In order to confirm the intestinal permeability from each experimental animal, FITC-dextran 400 mg/kg body weight dissolved in sterile saline was administered orally, followed by microvenous blood collection 0, 2, and 4 hours later. The obtained 100 μL of blood was centrifuged (12,000 × g, 10 min, 4 ℃) to take the supernatant, and the excitation wavelength was 485 nm and the emission wavelength was 535 nm using a microplate reader. It was set and the absorbance was measured. The concentration was calculated using the standard curve of FITC-dextran, and the concentration of FITC-dextran by time was expressed as an area under the curve (AUC).

3) Analysis result

Figure 4 shows the detection concentration of FITC-dextran in the normal feed group (NC), the high fat diet group (HFD), the positive control group (GC), the first experimental group (WEPL50), and the second experimental group (WEPL100) over time. It is a graph. 5 is a graph showing the area under the curve of the result measured from FIG. 4.

As shown in Figs. 4 and 5, when the normal feed group (NC) (normal control) was set to 100%, the high fat diet group (HFD) caused by leaky gut syndrome through a high fat diet was 399.61%, and the positive control group (normal control) was 399.61%. GC) was detected as 271.71%. That is, it can be seen that even if a high-fat diet was provided, intestinal permeability was suppressed when garcinia cambogia extract was administered in combination.

However, in the 1st and 2nd experimental groups to which the hot water extract prepared from Example 1 was co-administered, it was measured to be 125.97% and 104.98%, respectively, and it can be seen that the intestinal permeability was suppressed and decreased to a value that was quite similar to that of the normal feed group have. In particular, it was confirmed that the hot water extract of red pepper leaf prepared in Example 1 was administered at least 100 mg/kg to have the best effect.

Compared to the high fat diet group (HFD), intestinal permeability decreased by 3.17 times and 3.81 times in the first and second experimental groups, respectively. Therefore, it can be seen that the hot water extract of red pepper leaves according to the present invention has an improvement, prevention, or treatment effect on leaky intestinal syndrome.
