Description

  The present invention relates to a yuzu-derived composition for beautifying skin, and is applied, for example, as a raw material for foods and drinks, drugs, quasi drugs, cosmetics, and the like.

  Yuzu is a mandarin orange family, and its scientific name is Citrusjunos. Its origin is said to be Sichuan / Yunnan in the upper reaches of the Yangtze River in China. It is said that it was transmitted to Japan during the Heian period. The main line says that "If you drink Yuzu's seeds in black powder, you can relieve body pain." As a folk remedy, it is used for rheumatism, stiff shoulders, joint pain, etc. It is used as hot water to prevent colds and recover from fatigue. Ingredients include limonoids, which are bitter components contained in citrus fruits. Recent studies have reported that limonoids have an antitumor effect (Japanese Patent Laid-Open No. 2-83320), an analgesic action (Japanese Patent Laid-Open No. 9-286789), and a serum lipid metabolism improving action (Japanese Patent Laid-Open No. 10-280411).

  Under such a background, the present inventors have found that an extract extracted from yuzu seeds has a new whitening and skin beautifying action. Furthermore, an object of the present invention is to provide a safe food composition, pharmaceutical composition or cosmetic composition that is derived from a natural edible plant and has no side effects and can be taken for a long time.

  The objective of this invention is providing the food / beverage products, chemical | medical agent, and external preparation for skin containing the composition for skin beautification derived from a citron.

The skin-beautifying composition of the present invention for solving the above-mentioned problems contains a yuzu seed solvent extract.
Moreover, the composition for beautiful skin of the present invention is such that the solvent extract is n-hexane, ether, acetone, ethyl acetate, methanol, ethanol, isopropyl alcohol, butanol, 1,3-butylene glycol, ethylene glycol, propylene glycol, glycerin. And an extract extracted with one or more solvents of water or a supercritical extract with carbon dioxide gas.
Moreover, the composition for beautiful skin of the present invention is characterized in that the solvent extract is a hydrous ethanol extract having an ethanol concentration of 10 to 90% (wt / wt).

  As a raw material for extracting the composition for skin beautification according to the present invention, yuzu fruits, fruit juices, pericarps, fungi and the like can be used, and seeds are particularly preferred.

Solvents for extracting lipid metabolism improving functional components from yuzu include n-hexane, ether, acetone, ethyl acetate, methanol, ethanol, isopropyl alcohol, butanol, 1,3-butylene glycol, ethylene glycol, propylene glycol, glycerin , And water can be used. Two or more of these solvents may be mixed. Alternatively, supercritical extraction with carbon dioxide gas may be used.
Desirably, when water or ethanol is used as the extraction solvent, the active ingredient is efficiently extracted. In particular, hydrous ethanol is an extraction solvent that is less likely to reduce the activity of the active ingredient during extraction and is preferable from the standpoint of safety in the use of the extract in food. The kind of water for extraction is not particularly limited, and tap water, distilled water, mineral water, alkaline ionized water, deep water and the like can be used.

  As the extraction temperature for extracting the yuzu seed solvent extract, for example, when water-containing ethanol is used, the extraction temperature is 20 to 80 ° C., preferably about 50 to 80 ° C. This is because if the extraction temperature is too low, it becomes difficult to extract the active ingredient, and if the extraction temperature is too high, the activity of the active ingredient tends to decrease.

  The water-containing ethanol as the extraction solvent has an ethanol concentration of 10 to 90% (wt / wt), desirably an ethanol concentration of 60 to 80% (wt / wt). The reason why the ethanol concentration is 60% (wt / wt) or more is that when the ethanol content is too small, the extraction amount of the active ingredient tends to be insufficient. In addition, in order to improve the content rate of an active ingredient, it is good to perform ethanol extraction repeatedly, changing ethanol concentration in steps.

  As a method for extracting functional components derived from these seeds, any method such as continuous extraction, immersion extraction, countercurrent extraction, and supercritical extraction can be employed, and any apparatus can be used at room temperature or under heating. Can do.

A specific method for extracting a Yuzu seed solvent extract is as follows: an extraction raw material Yuzu seed) is introduced into a treatment tank filled with the extraction solvent, and the active ingredient is eluted while stirring. The raw material for extraction may be used as it is, but if it is pulverized beforehand, the extraction efficiency is good. For example, when water-containing ethanol is used as the extraction solvent, the extraction solvent is used in an amount of about 5 to 100 times (weight ratio) of the extraction raw material, and extraction is performed for about 30 minutes to 2 hours. The active ingredient is eluted in the solvent, and then filtered to remove the extraction residue to obtain an extract. Thereafter, the extract is subjected to treatments such as dilution, concentration, drying, purification and the like according to a conventional method to obtain the skin beautifying composition according to the present invention.
Examples of the purification method include activated carbon treatment, resin adsorption treatment, ion exchange resin, liquid-liquid countercurrent distribution, and the like.

  Examples of the present invention will be described below. In addition, the Example shown below is demonstrated in order to confirm the skin beautifying action etc. of the composition obtained by this invention, and the range of this invention is not limited to these products and manufacturing methods. .

[Production of skin beautifying composition]
Yuzu used as a raw material was made in Japan. First, yuzu seeds were pulverized and extracted with n-hexane at 60 ° C. for 1 hour. This was filtered, and the residue was extracted with 70% ethanol at 70 ° C. for 4 hours. After filtration, the filtrate was distilled under reduced pressure. Furthermore, what was made into the powder form by vacuum-drying was used as the yuzu seed solvent extract.

[Evaluation of Composition for Beautiful Skin]
In order to examine the effect of the skin beautifying composition of the present invention, using B16 melanoma cells, the action of vitamin C or arbutin, which has been conventionally known to have an inhibitory action on melanin production, and the extract of yuzu solvent was compared. It was. In addition, 100 g of yuzu seed solvent extract used in the test contains 1.3 g of water, 9.4 g of protein, 4.1 g of lipid, 5.7 g of ash, 0.3 g of dietary fiber, and 2.6% of limonin.

In the test method, B16 cells were suspended (5 × 10 ⁴ cells / mL) in a 2 mM theophylline-containing MEM medium (10% FCS, containing penicillin / streptomycin), and 500 μL was seeded in a 24-well plate. Sample solutions (55 μL) adjusted to various concentrations were added and cultured for 3 days, then the medium was removed, PBS (300 μL) was added, and the cells were sonicated. The crushed liquid was collected in a 96-well plate, and the absorbance (measurement wavelength: 415 nm, reference wavelength: 700 nm) was measured. The inhibition rate of melanin production was (absorbance of sample / absorbance of control × 100).

The result of the melanin production inhibitory effect in B16 melanoma cell was shown in FIG. The graph represents the inhibition rate of melanin production as an average value ± standard error.
YUZU SEED EXTRACT showed a melanin production inhibitory effect in a concentration-dependent manner, and showed no cytotoxicity at the same concentration. Moreover, although the melanin production inhibitory action (A) of the yuzu seed extract was somewhat inferior to arbutin (C), it was stronger than vitamin C (B). From these results, it was confirmed that Yuzu seed extract has an excellent whitening effect.

[Evaluation of Composition for Beautiful Skin]
The effect of Yuzu seed extract was measured using a human skin remodeling model (TESTSKIN: manufactured by Toyobo Co., Ltd.). The sample was dissolved in DMSO and added to the dermis layer side so that the final concentrations were 10 and 100 μg / ml. The medium was changed every 3 days and cultured for a total of 6 days. A tissue cross-section specimen was prepared after dipping in 10% formalin.

  Each layer shown in FIG. 2 is a dermis layer composed of collagen and fibroblasts from the bottom, the middle layer is the epidermis layer, and the upper layer is the stratum corneum. Compared with the control epidermis layer, in the sample treated with YUZU SEED EXTRACT 10 and 100 μg / ml, the epidermis layer tended to increase in thickness. This suggested that the addition of the sample might promote the generation of epidermal cells (basal layer). In the dermis layer, layer thickening was observed depending on the concentration of the sample. This may be due to increased production of collagen, which is a dermal component, or proliferation of fibroblasts. From these results, it was suggested that YUZU SEED EXTRACT promotes the production of epidermal cells and the production of collagen and fibroblasts, which are dermal components, and as a result, promotes turnover.

[Evaluation of skin beautification]
In order to investigate the effect of the skin beautifying composition of the present invention, a yuzu seed extract intake monitor test was conducted on 8 healthy women.

  Eight healthy women who agreed to participate in this study were selected and tested. The age was 23 to 41 years and the study period was 4 weeks. The measurement of the cosmetic parameters was performed twice before taking the test substance and after 4 weeks. The test article was prepared by adding 4 times the amount of excipients to YUZU SEED EXTRACT and encapsulating it, and taking 2 capsules per day (80 mg as YUZU SEED EXTRACT). As for the cosmetic parameters, the moisture content of the skin was measured using a moisture meter (CORNOMETER CM825: manufactured by Curage + Khazaka Co.) in the lower left eye. In addition, as a self-assessment of the monitor's own skin quality, a questionnaire survey was conducted after taking for 4 weeks on items such as “makeup paste” and “dullness”.

FIG. 3 shows the change in the amount of water in the lower left eye region after 4 weeks from the start.
From this, it was suggested that Yuzu Seed Extract has the function of enhancing the skin moisturizing effect.

  A self-reported questionnaire survey was conducted on the skin condition after ingestion of the test substance. The results are shown in FIG. Thereby, the improvement effect of the whole skin quality can be confirmed. In particular, the degree of improvement in items related to moisturizing, including “dryness”, is high. This is considered to be because the skin quality was improved because the moisture content of the skin increased.
