Especially, skin carries about 65 ~ 70% of the human body's moisture, that is, various physiologically active substances necessary for the human body, and helps to keep the skin soft and moist, It plays a role. The epidermis is divided into the stratum corneum, granular layer, the superficial layer and the basal layer in the order from the outside. The cells of the stratum corneum act like bricks, and the intercellular lipids between the keratinocytes function as the mortar, (J. Invest. Dermatol. 80 (Suppl.), 44-49, 1983). Recently, it has been newly found that not only the water content in the stratum corneum is increased but also the differentiation process developed from the keratinocytes in the basal layer to the keratinocytes in the outermost stratum corneum can be performed normally to function as a skin moisture retention barrier lost. In other words, physiological skin drying results in prolonged removal time of the stratum corneum, lowering lipid synthesis ability of epidermal cells, and decreasing the amount of moisturizing factors and lipids in the stratum corneum of the skin. Therefore, by promoting differentiation of keratinocytes, . Therefore, it can be expected that an excellent skin moisturizing effect can be obtained by using a water retaining material in the stratum corneum and a substance promoting keratinization promotion together.

[Example 1] Production of fermented herbal medicine extract

The dried granules were crushed and homogenized by a homomixer to obtain a fine powder phase. The pulverized herbal medicine was again pulverized with an atomizer (USA) and passed through a screen (pie 0.8 mm, ROUND HALL). After repeating this process, the mixture was passed through a ROUND HALL having a diameter of 0.3 mm and then sieved with a sieve (standard body, 200 mesh) to obtain a superfine powdery phase. The obtained herbal powder was added to 1.5 L of purified water so as to have a concentration of 3% by weight, and was adjusted to a proper pH (5.0 to 7.5) using sodium hydroxide as a basic composition, such as carbon source, nitrogen source, phosphate salt, I did it.

The culture medium was supplemented with Sacchromyces S. cerevisiae was inoculated into a basic medium containing 10 ⁶ cells / mL of herbal powder and cultured for 36 hours at pH 5.5 to 6.5, temperature 25 to 35 ° C, aeration amount 0.05 to 0.5 VVM.

The fermentation broth was centrifuged at 10,000 × g for 30 minutes to obtain a final fermentation broth extract of herbaceous material from which the polymer precipitate and the lactic acid bacteria were removed.

[Comparative Example 1] Preparation of herbal medicine extract

The extracts were extracted with 30% by weight of distilled water by adding distilled water as an extracting solvent. After cooling for 3 days, the mixture was filtered with a 0.2 ㎛ filter to prevent the formation of a precipitate. Ultrasonic herbal extracts were prepared by UV light for 3 days for sterilization.

[Experimental Example 1] Differentiation inducing effect in keratinocytes

The following experiments were conducted to examine the differentiation inducing effects of keratinocytes in the extracts of fermented herbal medicines and herbal medicine extracts.

First, human keratinocytes were put into a 96-well microtiter plate containing KGM (Keratinocyte Growth Media) medium containing 1.0% fetal bovine serum at a concentration of 5,000 cells / well, And then cultured in KGM medium without fetal bovine serum and grown to 70 ~ 80%. The cultured human keratinocytes were placed in a culture flask and grown to about 80%.

Then, 200 μl of each of the fermented extract of herb medicine of Example 1 and the herbal medicine extract of Comparative Example 1 was treated for 4 days, and then the protein was dissolved by mixing a urea, a reducing agent such as SDS and β-mercaptoethanol, Respectively. The remaining horny layer was then measured for peptide concentration at 310 nm and the absorbance values were compared. At this time, the low-concentration calcium (0.05 mM) treatment group without the extract treatment was used as a negative control group, and the high calcium concentration treatment group (1.5 mM) treatment not treated with the extract was used as a positive control group.

As a result, the proliferation effect of keratinocytes was 75% in Example 1 and 38% in Comparative Example 1 as shown in Table 1 below. As a result, it can be seen that the effect of inducing keratinocyte differentiation is enhanced in the herbal medicine fermentation extract rather than the herbal medicine extract.
