2. Description of the Related Art When human beings maintain a healthy body, SOD which is an active oxygen scavenging enzyme in the living body and active oxygen in the body
(Superoxide dismutase) is always balanced and the concentration of active oxygen is kept almost constant. However, currently, SOD production is decreased due to imbalance of dietary habits, excessive stress, and aging, and on the other hand, active oxygen is increased due to smoking, air pollution and the like.

As a result, active oxygen is excessively present in the living body, causing various tissue disorders. Particularly in the elderly, the SOD activity decreases and the active oxygen concentration increases, causing disorders such as rheumatoid arthritis and Pechet's disease. In addition, lipid peroxides generated by active oxygen, myocardial infarction, stroke, cataract, spots, freckles, wrinkles,
It is a leading cause of modern diseases such as diabetes, arteriosclerosis, stiff shoulders, and coldness.

In addition, even if not aged, active oxygen is particularly likely to be generated at a site such as the skin which is directly stimulated by environmental factors such as ultraviolet rays, so that the melanin pigment increases with the increase of the active oxygen concentration. It is easy to cause problems such as the generation of blemishes, stains, and wrinkles.

Therefore, SODs that eliminate excess active oxygen, which causes various disorders as described above, have attracted attention, and in order to prevent or treat these disorders, SODs are used as medicines, cosmetics and foods. Attempts have been made to add and use.

However, since SOD is heat-labile, deactivates by oral administration, and is extremely expensive, elimination of active oxygen by SOD has not been successful.

[0007] In view of the above circumstances, studies on active oxygen scavengers (including antioxidants that act similarly to SOD enzymes) have been conducted, and active oxygen scavengers using crude drug extract and the like have also been developed. At present, not only is it expensive due to a special raw material, but it is also difficult to supply a stable material.

[0008]

Since various obstacles caused by active oxygen have been recognized as described above, various studies have been actively conducted to eliminate active oxygen in the living body. In addition, nowadays, it is desired to live in a healthier and older life with the aging society. On the other hand, active oxygen scavengers are also attracting attention from the viewpoint of beauty. Therefore, there is a demand for the development of an active oxygen scavenger that is safe and inexpensive for the human body, has an excellent effect of scavenging active oxygen that causes various disorders, and that can be easily manufactured and can be stably supplied.

[0009]

Means for Solving the Problems The present inventors developed an active oxygen scavenger (Japanese Patent Application No. 3-324029) using an extract of rice in the course of conducting comprehensive utilization research of rice.
However, using rice as a raw material inevitably increases the cost. Therefore, we have conducted studies on the comprehensive utilization of cereals by picking up cereals represented by barley, wheat, and corn, which are cheaper than rice and used as staple foods in various parts of the world and have been proved to be highly safe.

[0010] As one of the themes, an intensive research was conducted on an active oxygen scavenger from cereals, and the active oxygen scavenging effect of the juice or the extract as it was or from the grain was measured. It was found that there was a remarkable effect of eliminating active oxygen, and the present invention was completed.

[0011] That is, the present invention is an active oxygen scavenger characterized by containing the juice extracted from grains except rice or the water extract or organic solvent extract from grains as they are or containing them. A very excellent active oxygen scavenger that exhibits the above effects simply, inexpensively, and completely safely by squeezing the grains or extracting the grains with water (including acid and alkali extraction) or organic solvents such as alcohol. Is obtained. The term "grains" as used herein refers to wheat excluding rice, barley, corn, hie, fluff, buckwheat, rye, and the like.

In the case of extracting grains with water or organic solvent, first, if the grains are pulverized or pulverized, the surface area becomes large, so that the extraction efficiency becomes extremely good. This method may be a general method using a crusher or a rice mill. It does not have to be ground, but in this case it takes a long time to decompose and extract the grain tissue.

In the water extraction, the grain is hydrated as it is, preferably crushed or powdered. The grain may be brown grain or refined grain. The amount of water added can be efficiently extracted in an amount of 2 to 5 times that of the grain, but may be appropriately selected depending on the yield, workability, purpose of final use and the like. After that, the mixture is heated and the extraction is completed at the time when it reaches a boiling state. After the extraction is completed, squeezing and filtration are performed depending on the purpose of use to obtain a clear extract. Note that hot water may be added from the beginning to perform extraction.

Although the active ingredient in the extract has not been clarified, it has been confirmed that this unknown active ingredient is stable to heat. Therefore, the extraction temperature at the time of water extraction is efficiently high. If it is left at a low temperature for a long time, it can be sufficiently extracted. However, at a low temperature of 40 ° C. or lower, it is necessary to make the pH acidic or alkaline or to add a preservative. The extraction time may be several minutes in the case of boiling extraction, but several hours to one day are required in the case of moderate temperature below that. At low temperatures, it depends on the crushed state of the grain,
It takes a few days to a month. However, even in this case, it is more effective to heat at the end as much as possible.

The most problematic problem in water extraction is the gelatinization phenomenon. If it becomes pasty, not only the extraction efficiency will deteriorate, but it will be extremely difficult in actual work. In order to prevent this, the reaction may be carried out by adding amylase, or the starch may be decomposed by acidifying it with hydrochloric acid or the like. By using this method, it can be sufficiently solved and there is no problem in practice.

Since the active ingredient in the extract is stable to acids and alkalis, acid extraction or alkali extraction is also effective. Further, in the case of water extraction, a method of reacting with an enzyme (for example, cellulase) that acts on the grain tissue to perform pretreatment and performing extraction is efficient. This is probably because the pretreatment makes it easier for the active ingredient to be extracted.

Furthermore, it has been found that an extract having this effect can be extracted even by extraction with an organic solvent. This is extremely effective in advancing the elucidation of the active ingredient, and also in the usage of the active ingredient being concentratedly extracted or blended with a substance insoluble in water. In this case, it is preferable to pulverize or pulverize as much as possible. The organic solvent used here is preferably alcohol, such as alcohol, which is safe to administer to the human body.

Further, in the case of fresh grains such as corn (including those sterilized by heating), it was found that the extract having this effect can be obtained even in the juice obtained by squeezing the sample with a cloth or a press. However, water extraction or organic solvent extraction was more effective than this juice. It was also found that by extracting the residue after squeezing with water or an organic solvent, the effect was weak, but there was an action of eliminating active oxygen.

Further, the same effect was obtained by combining fermentations such as alcoholic fermentation and lactic acid fermentation. It should be noted that the extraction of the product of the present invention from cereals is more effective if organic solvent extraction or water extraction is performed as described above and the active ingredient in the extract is further solvent extracted. However, this is thought to be because the concentrated state is obtained, and the same effect can be obtained by concentrating.

In addition, depending on the intended use, sugar or dextrin may be contained in the juice or water extract to become sticky, or its effect may be an obstacle. In that case, dextrin may be saccharified with amylase and then the sugar may be removed by feeding it to yeast, fractionating the active ingredient with an adsorbent, or extracting with an organic solvent. In any case, the effect is obtained only by performing extraction, and unnecessary components may be removed by various methods depending on the application.

Since cereals are eaten as a staple food every day, and they are so close to us that there was no concept of using them as active oxygen scavengers, which was unexpected. In addition to staple foods, it has been used for beer, shochu, confectionery, etc., but the idea and method of extraction from grains has not been adopted. It is considered that this is due to the fact that when the grains are heated and extracted, they become pasty as a characteristic of the grain, which is very difficult in the conventional way of thinking. Therefore, in the present invention, organic solvent extraction, acid, alkali extraction is used, and in the case of water extraction, the purpose can be achieved by facilitating the extraction by allowing amylase to act. is there. Only when the extraction operation is sufficiently carried out in this way, it is possible to extract an extremely effective active ingredient as an active oxygen scavenger.

The effect of the present invention for eliminating active oxygen will be described below. First, the effect of the product of the present invention as a superoxide scavenger was examined. The test method was the NBT method.

Then, 0.1 ml of the sample solution is added, and after standing at 25 ° C. for 10 minutes, 0.1 ml of the xanthine oxidase solution is added, and the mixture is quickly stirred and incubated at 25 ° C. After 20 minutes, 0.1 ml of CuCl ₂ solution was added to stop the reaction, and the absorbance was measured at 560 nm. For comparison, instead of the sample, superoxide dismutase (Cu, Zn type SOD, activity 3000 to
4000 unit / mg Wako Pure Chemical Industries, Ltd.) The same procedure was performed for 0.1 ml of the aqueous solution, and this value was used as the superoxide elimination rate 1

[0025]

[Table 1] Note 1 Water extract was performed according to Example 1 Note 2 Organic solvent extract was performed according to Example 2 Note 3 Juice juice was performed according to Example 3

As described above, it was found that both the water extract and the organic solvent extract have a superoxide scavenging effect. Furthermore, it was found that the effect was almost the same even when alcoholic fermentation was performed.
It was also found that corn has a superoxide scavenging effect even when it is simply squeezed.

Next, the thermal stability of the product of the present invention was examined. First, the product of the present invention and SO obtained in Example 1
D was heat-treated at 90 ° C. for 10 minutes, and its superoxide scavenging ability was examined. The superoxide erasing rate was measured by the above method. The results are shown in Table 2.

[0028]

[Table 2] Note: As in Table 1, each extract used was that obtained in each Example.

As described above, it was found that SOD is unstable to heat, but all the products of the present invention have excellent thermal stability. From this, it can be said that the active ingredient for eliminating active oxygen in the product of the present invention has excellent stability against heat. Since the product of the present invention shows a very remarkable active oxygen scavenging effect and is safe, it can be used for pharmaceuticals, cosmetics,
It can be used for food. Next, these applications will be described.

As a medicine, it can be used as an anti-ulcer agent. The test methods for examining the anti-ulcer action of the product of the present invention and the results thereof are shown below. First, the effect of oral administration of the product of the present invention on restricted water immersion stress ulcer was examined. The method was performed according to the method of Watanabe et al. That is, 8-week-old male ddY mice were fasted for 24 hours, and then the product of the present invention obtained in Example 1 was orally administered in an amount of 0.3 ml / mouse.
The xiphoid process was immersed in water at 5 ° C., and restrained water immersion stress was applied. After 5 hours, the cervical vertebrae were dislocated and sacrificed, and the stomach was excised. Then, 1.5 ml of a 1% formalin solution was injected into the stomach, and the stomach tissue was lightly fixed by immersing the solution in the same solution, and left as it was for 24 hours. Then, make an incision along the greater curvature and measure the length (mm) of the damage that has occurred in the glandular stomach,
The total sum per animal was expressed as an ulcer index. As a control, the same amount of physiological saline was orally administered 30 minutes before being put into a stress gauge. Fifteen mice each were used. The results are shown in Table 3.

[0031]

[Table 3]

As shown in Table 3, the average ulcer index in mice administered with physiological saline as a control was 65.
On the other hand, the average ulcer index in the mice to which the present invention product was administered was 33.0, clearly indicating that the present invention product is effective as an anti-ulcer agent against restraint water immersion stress ulcer by oral administration. It turned out to be. As a result, it was revealed that the product of the present invention directly acts from the gastrointestinal mucosa and exhibits an effective action as an anti-ulcer agent.

The product of the present invention can also be used as a skin treatment agent. The product of the present invention is applied daily to panelists of various skin diseases.
The results are shown in Table 4, which was applied twice a day in the morning and evening to the affected area and continuously applied for 1 month.

[0034]

[Table 4]

As shown in Table 4 above, since this product has various skin-treating effects, it can be seen that it has a fibroblast-activating effect and an antibacterial effect.
Moreover, since it is also useful for xeroderma, acne and the like, it can be seen that it also has a moisturizing effect and an effect of appropriately suppressing the increase of sebum, but actually suppresses this moisturizing effect and the increase of sebum. The test methods for examining the action and the results are shown below.

First, in order to demonstrate the strength of the moisturizing effect of the product of the present invention, a single coating test was conducted using a moisture meter (SKICON200). An environment in which the room temperature was 20 ° C. and the relative humidity was 65% was set as a measurement condition, and the panelists were allowed to rest in the above environment for about 10 minutes before the measurement. The test site (both sides) was selected on the flexion side of the forearm where no rash was observed. The panelists were five people who were suffering from xeroderma. The average value of changes in the water content of the stratum corneum between the main test (using the product of the present invention obtained in Example 1) read by a moisture meter and the control test (using water) is shown in FIG. The measurement method of the one-time application test is as follows.

Measurement method 1) A test site of 5 × 5 cm and a control site are set on the forearm flexion side of the panel. 2) Measure the water content of the stratum corneum at each site. 3) Measure the water content of the stratum corneum immediately after coating the sample and after 30, 60, 90 and 120 minutes.

From FIG. 1, it was confirmed that the water content of the stratum corneum of the product of the present invention increased about 10 times as much as that of the control, immediately after coating. In addition, regarding the period from 30 minutes to 120 minutes after the application, in the application site of the present invention, from the control 2 to 120 minutes.
It can be seen that the water content is tripled.

Next, in order to numerically demonstrate the therapeutic effect of the product of the present invention on xeroderma, a water load test was conducted using a moisture meter (SKICON200) before use of the product of the present invention and after use for 2 weeks. .. The panelists were the 5 persons used in FIG. 1, and the measurement conditions were the same as the one-time application test. A control (measurement at a site not coated with the product of the present invention) was always set so that the effect of the seasonal change in the water content of the living horny layer would not influence the effect determination. The stratum corneum water content was shown as the average value of 5 panelists. The result is shown in FIG. As the product of the present invention, the product obtained in Example 1 was used. The measuring method of the water load test is as follows.

Measuring Method 1) The water content of the stratum corneum of the test site is measured. 2) Place one drop of distilled water on the test site, and after 10 seconds, completely wipe off the water drop with dry gauze. 3) Immediately after wiping, the water content of the stratum corneum is measured after 30, 60, 90 and 120 seconds.

As shown in the graph of FIG. 2, by applying the product of the present invention, the water absorption capacity of the skin (the water content of the stratum corneum after 0 seconds of water loading minus the water content of the stratum corneum before loading) ),
It can be seen that both the water retention capacity (the curve drawn by the water content of the stratum corneum from 0 to 120 seconds after water loading) is improved at the same time.

That is, the skin before use of the product of the present invention has a very low water content in the stratum corneum before water loading (average of 4.7), and the water absorption capacity (average of 44.8) is considerably reduced. In addition, the stratum corneum of the skin of a normal person also has a water-retaining ability, and after 30 seconds of water loading, the stratum corneum of the skin of the normal person returns to the value before the water loading. These results show that the water absorption capacity, the water retention capacity, and the barrier function are all reduced in the measured morbid stratum corneum. On the other hand, the skin after use of the product of the present invention has a two- to three-fold increase in the water content of the stratum corneum and the water absorption capacity before water loading, and the water retention capacity is considerably improved to the same level as that of a normal person. I understood.

From the above, it can be said that the product of the present invention has an excellent effect on the water content of the pathological stratum corneum and the improvement of the barrier function. Further, when the product of the present invention is evaluated in combination with the moisturizing action obtained from the one-time application test, the product of the present invention increases the water absorption capacity and water retention capacity of the stratum corneum and absorbs a large amount of water from the outside world.
Furthermore, it can be said that it has a moisturizing action of giving the stratum corneum the property of not releasing the once absorbed water.

Further, in order to experimentally exemplify the effect of suppressing secretion of the amount of sebum of the product of the present invention, changes in the amount of sebum after washing the face were measured. As panelists, five persons randomly selected from the ones used in Table 4 were used, and the average value of the change in the amount of sebum between the main test (after washing the face and applying the product of the present invention) and the control test (only the face washing) was shown in FIG. It was shown to. As the product of the present invention, the product obtained in Example 1 was used.

As shown in the graph of FIG. 3, it was found that the application of the product of the present invention considerably suppressed the increase in the amount of sebum. The inhibitory effect on the amount of sebum secretion of the product of the present invention also confirmed the preventive and therapeutic effect on acne. It was revealed from the following tests that, when the product of the present invention was applied to the skin as a cosmetic, it had the effects of making the skin smooth and having a fine texture.

The product of the present invention was applied to the right arm site of a panelist twice a day for one month, and the site of application of the product of the present invention was measured by a dynamic friction meter. The same part of the left arm was used as a control. The panelists were 6 people. The measurement conditions are as follows. Temperature 25 ℃ Humidity 60% Sensor used KES-SE Friction tester SE-2 type (0.5mm piano wire used) Friction static load 50gf Measuring speed 1mm / sec Measuring distance 30mm (Integral effective range 20mm)

The MMD (coefficient of variation) was 0.0178 in the part of the left arm to which the product of the present invention was not applied, but in the part of the right arm to which the product of the present invention was applied for one month, the MMD was
(Coefficient of variation) dropped to 0.0072. The average values of 6 persons were almost the same. It is considered that this is because the fluctuation due to the unevenness of the surface was reduced, and from this, it became clear that the texture of the skin became finer and that the wrinkled skin became younger. At the same time, when MIU (friction coefficient) was also examined, it was 0.129 before the application, but the skin after application for 1 month dropped to 0.085, and it also has the effect of making the skin slippery. It has been found that it also has an anti-aging effect that makes it smooth like a young person.

Further, in order to exemplify the whitening effect of the present invention, a test for tyrosinase activity inhibitory effect was conducted. As an operation method, 1 ml each of a substrate solution (0.04% tyrosine solution) and a buffer solution (McllvaineBuffer pH 6.8) was accurately placed in an absorption cell, and 1 ml each of water and the product of the present invention obtained in Example 1 were obtained. Put each one accurately, stir and mix, and 35 ℃
After 5 minutes, adjust the absorbance scale to the wavelength of 475 nm and perform zero correction, and then add exactly 0.02 ml of tyrosinase solution (5.3 mg of tyrosinase dissolved in 0.9% NaCl solution) and immediately Incubated with agitation. The absorbance at this time was measured over time (every 3 minutes) and is shown in Table 5.

[0049]

[Table 5]

From the measurement results shown in Table 5, it can be seen that the product of the present invention has a tyrosinase activity inhibitory action. From this, it can be said that the product of the present invention has a whitening effect.

Further, as described above, the product of the present invention also has a moisturizing action enough to be used as a medicine. Therefore, all the basic effects of cosmetics are satisfied, and they have a wide range of applications such as creams, emulsions, lotions, cleansing, packs, and soaps. Also, by drinking the product of the present invention, the same effects as described above can be obtained.

The product of the present invention can also be used as a food preservative, antioxidant, and freshness-retaining agent. As a representative of Gram-positive bacteria, Bacillus subtili causes spoilage of rice and bread.
