Description

The present invention relates to a novel active ingredient derived from a natural product and having excellent physiological activity and biosafety, and an external preparation for the skin (including the scalp) and an oral composition for beauty or health promotion, which are formulated with the same. .

In recent years, research has been conducted on cell aging and damage to cells caused by external factors (e.g., ultraviolet rays, chemicals such as air pollutants and environmental hormones, allergens such as pollen, environmental stress, etc.), and various cell Mechanisms related to aging phenomena, cell damage, prevention, and recovery have been elucidated.

Active ingredients for preventing and improving the above-mentioned cell damage and aging phenomena have been proposed, and cosmetics, food and drink products, and pharmaceuticals containing these active ingredients have been put on the market. For example, antioxidants such as vitamin C, vitamin E, catalase, or their derivatives; anti-inflammatory agents such as glycyrrhizic acid or its salts, allantoin, tranexamic acid; various ultraviolet absorbers; α-hydroxycarboxylic acid, placenta extract and γ-amino-β-hydroxybutyric acid; extracellular matrix components such as collagen, elastin, hyaluronic acid or its salts; humectants such as urea; and protein glycation inhibitors such as aminoguanidine.

However, these conventional components have problems in terms of stability, safety, and effectiveness when actually applied to living organisms. For example, the above-mentioned ascorbic acid or its derivatives are easily oxidized by external factors such as ultraviolet rays or enzymes in the body, and there is a problem that their uptake into cells decreases with age.

As a result of intensive research to solve the above problems, the present inventors have discovered a fermented product of a plant of the Nelumbo family (Nelumbonaceae), a hydrolyzate of a plant of the genus Oryza (Poaceae), Extracts of Salicornia plants of the Chenopodiaceae family, and hydrolysates of soybeans or their extracts have been found to be effective in producing vitamin C transporters (vitamin C transporters), which are vitamin C channels involved in the uptake of vitamin C into cells. It was also found that it has the effect of promoting the synthesis of SVCT).

Conventionally, inventions have been made in which fermented products of plants of the genus Lotus of the Lotus family, hydrolysates of plants of the genus Poaceae of the genus Poaceae, extracts of plants of the genus Salicorum of the family Chenopodiaceae, and hydrolysates of soybeans or their extracts are used in external preparations for the skin. was known, for example, from Patent Documents 1 to 5. However, fermented products of plants of the Lotus genus of the Lotus family, extracts or hydrolysates of plants of the genus Poaceae of the Poaceae family, extracts of plants of the genus Salicorum of the Chenopodiaceae family, and hydrolysates of soybeans or their extracts are used to synthesize SVCT1. It was not known to have a promoting effect.

Fermentation temperature is generally in the range of 5 to 50°C, preferably 20 to 40°C, which is the optimum growth temperature for each microorganism (for example, 30 to 40°C for lactic acid bacteria, 25 to 30°C for yeast). is within the range of The number of days for fermentation is generally in the range of 1 to 10 days, preferably 2 to 5 days at the optimum temperature. If the number of fermentation days is shorter than the above general range, fermentation will not occur sufficiently and the effectiveness of the fermented product will tend to decrease, while if it is extended beyond 10 days, no further increase in effectiveness will be observed. In addition, coloring and fermentation odor increase, both of which are undesirable.

Test example 1. Sodium-dependent vitamin C transporter (SVCT) synthesis promotion effect Normal human epidermal melanocytes were prepared at 1 x ¹⁰ cells/mL using DermaLife (registered trademark) [manufactured by Kurabo Industries, Ltd.] containing a proliferation additive, and plated in a 96-well microplate. 100 μL each was inoculated and cultured at 37°C under 5% carbon dioxide gas and saturated water vapor. After 24 hours, a culture solution containing each of the fermented products of Production Examples 1 and 2, the hydrolysates of Production Examples 6 and 7, and the extracts of Production Examples 9 and 10 as sample solution 1 was added and further cultured. Here, sample solution 1 was prepared so that the final concentration as a solution with respect to the culture solution was 0.25%, 0.5%, and 1.0%. Further, the hydrolyzate of Production Example 12 was prepared as sample solution 2 so that the final concentration as a solution with respect to the culture solution was 2.0%. In addition, as a control, control group 1 was added with a culture solution containing PBS(-) (1.0%) in place of sample solution 1, and control group 1 was added with culture solution containing PBS(-) (2.0%) in place of sample solution 2. A control group 2 was set up in which the culture medium was additionally added. After 48 hours, the culture supernatant was removed, and 200 μL of PBS(-) was added and removed. Next, 50 μL of 10% trichloroacetic acid (Wako Pure Chemical Industries, Ltd.) was added and incubated for 30 minutes in the cold. Afterwards, the supernatant was removed. The plate was washed with 100 μL of PBS(-), and 50 μL of PBS(-) containing 0.2% Triton-X was added and incubated at room temperature for 1 hour. The supernatant was removed, 50 μL of PBS(-) containing 8% bovine serum albumin (SIGMA) was added, and the mixture was incubated at room temperature for 2 hours. The supernatant was removed and washed with 100 μL of PBS(-) containing 0.2% Triton-X, and 50 μL of anti-SVCT mouse monoclonal antibody (Santa Cruz) was added and incubated for 24 hours in the cold. The supernatant was removed and washing was repeated three times using 100 μL of PBS(-) containing 0.2% Triton-X. 50 μL of Alexa Fluor 488 anti-mouse secondary antibody (Life Technologies) was added and incubated at room temperature in the dark for 2 hours. Remove the supernatant and wash three times using 100 μL of PBS(-) containing 0.2% Triton-X, add 100 μL each of PBS(-), and use Ex485/Em520 using a fluorescence plate reader (Dainippon Pharmaceutical Co., Ltd.). The fluorescence intensity was measured. The relative value of the fluorescence intensity with respect to the measured value in the control group was defined as the SVCT synthesis rate (%).
