Description

Skin-lightening Composition Using an Extract of Shindari}

The present invention relates to a composition for skin whitening using fifties and oak petals mixed extract.

The skin is the largest organ that protects the interior of our body from a variety of external environments and is the outermost organ of our body. These skins contain keratinocytes, which inhibit the invasion of foreign substances, Langerhans cells and macrophages, which are responsible for skin immunity, fibroblasts, which maintain skin tissue, and pigment production. There are melanocytes (melanocytes) and the like.

Melanin is a black pigment synthesized in melanocytes and is a protein complex that serves to protect skin cells from the external environment such as ultraviolet rays. However, the overproduction of melanin can cause blemishes, freckles, and even skin cancer in the human body (JP Ortonne and JJ Nordlund, The pigmentary system: physiology and pathophysiology, eds. JJ Norlund, RE Boissy, VJ Hearing, RA King and JP Ortonne, 489, Oxford University Press, New York, 1998).

Such melanin is produced by the action of tyrosinase and tyrosinase related protein present in melanocytes. Specifically, tyrosine is oxidized by tyrosinase and is converted into dopa (DOPA, 3,4-dihydroxyphenylalanine), followed by dopaoxidase to oxidize the dopa to be dopaquinone. After conversion, it is produced by the action of tyrosinase-related proteins TRP-1 (5,6-dihydroxy indole-2-carboxylic acid oxidase) and TRP-2 (dopachrome tautomerase). Tyrosinase, TRP-1 and TRP-2 are promoted by the transcription factors microphthalmia-associated transcription factor (MITF), which is known to inhibit the expression of extracellular signal-regulated kinase (ERK) (DS). Kim, et al., J Cell Sci. 2003; 116: 1699-706).

Since tyrosinase is involved as the first step in producing melanin, the research on whitening agents has been mainly focused on finding tyrosinase inhibitors (Kor. J. Pharmacogn., 44 (3): 220, 2013). Most of the whitening agents currently used are such tyrosinase inhibitors, and hydroquinone or its glycosides, arbutin (β-D-glucopyranoside) and kojic acid, all inhibit tyrosinase inhibitory activity. Having whitening agents. Hydroquinone or its glycoside, arbutin (β-D-glucopyranoside), is a competitive inhibitor of tyrosinase activity, and kojic acid chelates tyrosinase active sites in tyrosine. It is a substance that inhibits the process of dopa and dopaquinone (Korean J. Plant Res., 26 (5): 526, 2013; J. Korean Soc.Food Sci.Nutr., 41 (2): 156, 2012) .

However, all of the whitening agents are synthetic whitening agents, and these synthetic whitening agents have side effects such as dermatitis, erythema, vitiligo, and burns for a long time, and in some countries such as Taiwan, allowable concentrations can be used without prescription from medical professionals. Recently, researches to find a whitening material from natural products with relatively little irritation or side effects on human skin have been actively conducted due to such safety issues of synthetic whitening agents.

On the other hand, shien-dari is a low-alcoholic beverage made by fermenting yeast in rice, barley rice, or rice that has just started to rest. It is also called a new moon or a single drink. When it is difficult to store leftover rice, it is derived from using it. When the rice becomes fermented and the shape is not recognizable, it is sifted and eaten raw or boiled. It fermented for a day or two in summer and 5 or 6 days in winter. The short fermentation period is about 1% lower, and the acidity and sweetness are strong. Sheen is similar to makgeolli with barley (or rice), yeast, and water, but is similar to yogurt than makgeolli due to its short fermentation and low alcohol content.

Recently, as interest in health has increased, interest in the fifties using fermented bacteria beneficial to the body has increased. The effects of fifty-legged legs on intestinal health improvement and dementia improvement are known and attempts are being made to apply them to new fields such as cosmetics as well as food using useful ingredients. Known studies include changes in composition during the production of fifty legs (Kim SC. 1998. Master thesis.Jeju National University of Korea. Soc Food Sci Nutr 28 (5): 1017-1021), Characterization of Sheen Legs Prepared with Citrus Fruits (Kim HS. 2011. Master thesis.Jeju National University of Korea, 40p), Characterization of Sheen Legs with Carrots (Kim S et al., 2015. Korean J Food Cook Sci. 31 (1) 009-017), and the method of manufacturing fifty-legged legs with improved presentation odor (Korean Patent No. 1396825).

The present invention discloses the use of fifty-legged extract as a skin whitening agent based on melanin production inhibitory activity.

Hereinafter, the present invention will be described with reference to Examples and Experimental Examples. However, the scope of the present invention is not limited to these examples and experimental examples.

<Example> Flower Petal Extract and Sheen Leg Extract Preparation

Example 1 Preparation of Oak Flower Petal Extracts

Chamkkot Tree (Rhododendron weyrichii) then was added to 70% ethanol of 10 times the weight of the petal powder extracted at room temperature for 24 hours and filtered with a filter paper. The filtrate was concentrated under reduced pressure and lyophilized to obtain an oak extract.

<Example 2> Preparation of fifty-legged extract

10-fold weight of 70% ethanol was added to fifty-legged powder, and extracted at room temperature for 24 hours, followed by filtration through filter paper. The filtrate was concentrated under reduced pressure and lyophilized to obtain fifty-legged extract.

Experimental Example Whitening activity check

<1> Experiment method

<1-1> Cell culture

B16F10 cells, a mouse melanoma cell line, were purchased from the Korean Cell Line Bank, with 1% antibiotics (Gibco, USA) and 10% fetal bovine serum (FBS; Gibco, Grand Island, USA). The DMEM medium (Dulbecco's modified Eagle's medium) containing this was incubated in a 37 ℃, 5% CO 2 incubator, and passaged once every 4 days.

<1-2> Cytotoxicity Assessment

MTT analysis was performed to determine the effect of the sample of Example on cell growth. Live metabolism-rich living cells are water-soluble yellow MTT (3- (4,5-dimethylthiaxo-2-yl) -2,5-diphenyl tetrazolium bromide) (Sigma, MO, USA) by the dehydrogenase action of mitochondria in cells. ) To form a purple water-insoluble formazan.

B16F10 cells were added to a 96 well plate at 2.0 × 10 4 cells / mL using DMEM medium to which 10% FBS was added, and 18 hours of incubation were performed. Then 50 μl of MTT solution was added and reacted for 4 hours. After completely removing the culture medium and adding 200 µl of dimethylsulfoxide to completely dissolve the precipitate, the absorbance of 540 nm was measured using a microplate reader. The average absorbance value for each sample group was obtained, and cell growth rate was evaluated by comparing with the absorbance value of the control group.

<1-3> Measurement of melanin biosynthesis inhibitory activity

B16F10 cells incubated in DMEM medium were dispensed in a 24 well plate at 2.0 × 10 4 cells / well, and then cultured for 24 hours and treated with 100 nM of α-MSH (-melanocyte stimulating hormone) and the sample prepared in the same manner at the same time. Time incubation. Next, the cells were washed with phosphate buffer (pH 7.4), and cell lysis buffer (100 mM sodium phosphate (pH6.8), 0.1 mM PMSF, 1% Triton X-100) was added, and the cells were lysed at -80 ° C for 30 minutes. Next, 1N NaOH was added to the cell lysate and reacted at 80 ° C. for 1 hour to dissolve the precipitate, and the absorbance was measured at 405 nm using a spectrophotometer. Inhibition of melanin biosynthesis was indicated by the decrease in absorbance of the addition and no addition of the sample solution.

After treating the B16F10 cells with an example extract and incubating for 48 hours, the results of confirming cell viability using the MTT assay are shown in FIG. 1. Referring to [FIG. 1], it can be confirmed that all of the extract extracts do not exhibit cytotoxicity.

<2-1> melanin synthesis amount measurement result

In order to evaluate the possibility of using the extract as a natural whitening agent, B16F10 cells, which are mouse melanoma cells, were treated with the extract extract and α-MSH, which is a melanogenesis-inducing agent, to produce melanin induced by α-MSH. The degree of inhibition by was measured, and the results are shown in FIG. 2. Referring to Figure 2 it can be seen that the production of melanin induced by α-MSH decreases in a concentration-dependent manner by the example extract.
