Description

The present invention relates to antioxidants, cosmetics, food and beverage compositions and pharmaceutical compositions, and in particular, is excellent in the effect of improving various skin problems such as rough skin caused by ultraviolet rays, wrinkles, pigmentation, acne and dermatitis. The present invention relates to antioxidants, cosmetics, food and beverage compositions, and pharmaceutical compositions.

Since skin is the outermost layer of the body, it is easily affected by environmental factors in daily life. Ultraviolet rays and the active oxygen and lipid peroxides that are generated by it cause inflammation and other tissues such as skin. Cause a lot of damage. In addition, these inflammations and skin damage cause various skin troubles such as rough skin, wrinkles, pigmentation, acne, and dermatitis, along with a decrease in skin function due to aging.

In order to improve various skin problems such as rough skin, wrinkles, pigmentation, acne and dermatitis induced by aging and ultraviolet rays in such daily life, cosmetics, food and beverage compositions and pharmaceutical compositions have been conventionally used. Synthetic antioxidants (dibutylhydroxytoluene, butylhydroxyanisole, etc.) and naturally-derived antioxidants (α-tocopherol, ascorbic acid, etc.) are used as products. However, these antioxidants still have many problems in terms of safety and stability. For example, butylhydroxyanisole is currently prohibited from being used because it has been confirmed to be carcinogenic. Moreover, ascorbic acid is easily decomposed and has a problem in terms of stability.

In recent years, various antioxidant substances extracted from plant seeds, leaves, rhizomes, and the like have been produced, and have been tried to be incorporated into cosmetics, pharmaceutical compositions, food and beverage compositions, and the like. As a material using plant-derived raw materials, for example, an antioxidant stress product having a high antioxidant property composed of a natural antioxidant and an antioxidant vitamin (see, for example, Patent Document 1) is disclosed. Antioxidants such as matcha, sesame, highly antioxidant spices and herbs (rosemary, sage, thyme, ginger, allspice, cinnamon, kiraway, fennel, coriander, pepper, cardamom), cocoa powder, lactic acid bacteria Euglena cells are mentioned. Moreover, the antioxidant (for example, refer patent document 2) containing the tannin derived from baking chestnut skin, the antioxidant (for example, refer patent document 3) containing the solvent extract of a cacao pod outer skin, etc. are also known. It has been.
On the other hand, a compound obtained by subjecting arginine and glucose or maltose to a Maillard reaction in the presence of an acid has a vasodilatory effect (see, for example, Patent Document 4), an anti-inflammatory effect, and TNF-α production inhibition. It has an action, cyclooxygenase-2 activity inhibition action, anti-aging action, type I collagen production promotion action, type IV collagen production promotion action, transglutaminase-1 production promotion action, hyaluronic acid production promotion action and nitric oxide production promotion action (For example, refer to Patent Document 5).

・ Sample preparation (production of fructosyl citrulline)
A mixture of 2 g of citrulline, 2 g of glucose and 50 ml of glacial acetic acid was heated and stirred at 80 ° C. for 30 minutes. The obtained solution was filtered, and the filtrate was concentrated and dried to obtain 2.6 g of a mixture. This is redissolved in 50 ml of water, applied to a column filled with a cation exchange resin, and eluted with 1% aqueous ammonia. The eluate was concentrated and freeze-dried to obtain 1.1 g of fructosyl citrulline fraction. The obtained fructosyl citrulline fraction (1.1 g) was purified with a silica gel column and Biogel P-2 to obtain 0.38 g of fructosyl citrulline. This fructosyl citrulline is a mixture of the compound represented by the general formula (1) and the compound represented by the general formula (2).

Measurement of radical scavenging action The radical scavenging action of fructosyl citrulline obtained in the above production was measured using 2,2-Diphenyl-1-picryldrazyl (manufactured by Sigma, hereinafter abbreviated as DPPH). As an experimental operation method, 0.1 ml of 0.8 mM DPPH solution, 0.1 ml of 80% ethanol, 0.1 ml of 2M MES buffer (pH 6.0), and addition adjusted so as to have the addition concentrations shown in Table 1 0.1 ml of an 80% ethanol solution of the test substance was added, and the absorbance at a wavelength of 520 nm was measured. For the measurement of absorbance, an SH-1000 microplate reader manufactured by Corona Electric Co., Ltd. was used. Table 1 shows the measurement results of the radical scavenging action of fructosyl citrulline.

As is apparent from the results shown in Table 1, fructosyl citrulline exhibited a radical scavenging action in a concentration-dependent manner.

-Measurement of cytotoxicity The cytotoxicity of the fructosyl citrulline obtained in the above production was evaluated using human normal neonatal skin fibroblasts (NHDF). As an experimental operation method, human normal neonatal skin fibroblasts were cultured using Eagle's MEM medium containing 10% bovine serum, and then cells were collected by trypsin / EDTA solution treatment to give a concentration of 1 × 10 5 cells / mL. After diluting with 2% bovine serum-containing Eagle's MEM medium, 2 × 10 ⁴ cells were seeded on a 48-well culture plate and cultured at 37 ° C. for 24 hours in a 5% CO 2 environment. After completion of the culture, an Eagle's MEM medium containing 2% bovine serum containing fructosyl citrulline was added and further cultured for 24 hours, and the influence on the cells was evaluated by measuring the viability of the cells. The cell viability was calculated based on the number of cells in each Example, assuming that the number of cells in Comparative Example 1 was 100%. A larger value indicates a cell activation effect and does not show cytotoxicity. On the other hand, when it becomes 100% or less, it shows cytotoxicity.

As is apparent from the results shown in Table 2, fructosyl citrulline exhibited a cell activation effect in a concentration-dependent manner and did not show cytotoxicity.
