Hereinafter, the present invention will be described in more detail with reference to Experimental Examples and Examples. However, these experimental examples and examples are provided only for the purpose of illustration in order to help the understanding of the present invention is not limited to the scope and scope of the present invention.

Experimental Example

The inventors have conducted experiments on skin improvement and / or activation effects on root skin extracts. It was shown by the following experiment that the root extract has the effect of improving wrinkles, promoting collagen synthesis, and moisturizing.

1) Wrinkle improvement effect

As a wrinkle improvement effect, skin cell proliferation effect was investigated at each concentration.

Human fibroblasts are cultured in Dulbecco's Modified Eagle's Medium (DMEM) medium containing 2.5% bovine fetal serum, and 5,000 cells per well are plated in 96-well microtiter plates. Was added. The root extract was added to each well and stored at 37 ° C. for 4 days. 0.2% 3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium (3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium after incubation MTT) was added at 50 μl / well. Each plate obtained formazan at 37 ° C. in time. This formazan becomes an indicator of cell density or survival rate. After dissolving formazan in DMSO (dimethyl sulfoxide), the absorbance at 570 nm was measured using a microplate reader.

The proliferative effect of fibroblasts from rooted bark extracts at each time of day was 0.01-0.1% to 35% at 12 hours and 50% at 1% concentration at 24 hours. In addition, no cytotoxicity was found at concentrations of 0.0001-10%.

Figure 2 shows the results of the skin cell proliferation effect of the root extract of each concentration.

2) collagen synthesis promoting effect

Fibroblasts were placed in root extract and incubated for 24 hours on a 24-well microtiter plate containing DMEM medium. After incubation, 0.5 ml DMEM and 10 μCi of L [2,3,4,5-3H] -proline were added to each well. After 24 hours it was washed with 5% trichloroacetic acid and separated into two test tubes for each. In one test tube, collagenase type I was added at 1 unit / μl and maintained at 37 ° C for 90 minutes. The other test tube was kept at 4 ° C. Then 0.05 ml of 50% trichloroacetic acid was added to each test tube and maintained at 4 ° C. for 20 minutes. Each solution was then centrifuged at 12,000 rpm for 10 minutes. Relative collagen biosynthesis was calculated for the collagen thus separated.

Samples treated with root extract at 0.01% concentration increased collagen biosynthesis by 40% compared to untreated control.

Specific experimental and calculation methods for collagen biosynthesis have been described in conventional publications (Green, MLJI mmunol. Methods. 70, 257-268 (1984); Hockley, K. Fd Chem Toxicol. 24 (6/7). 473-475 (1986); Zhang, J. Clinica Chimica Acta, 219, 1-14 (1993); Schwartz, E. J Invest Dermatol. 96, 975-978 (1991). Collagen is a biomaterial that accounts for most of the skin's connective tissue. It is related to skin elasticity and decreases with age. Therefore, increasing the amount of collagen biosynthesis can increase the elasticity of the skin.

3) moisturizing effect

Moisturizing effect of root extract was compared with hyaluronic acid, a representative moisturizer. 0.5% root extract and 0.5% hyaluronic acid were applied inside the arms of 10 test subjects and taped. Skin hydration was obtained by measuring conductance before, immediately after and 2 hours after treatment.

In the case of hyaluronic acid, the skin moisturization rate decreased from 35% immediately after treatment to 5% after 2 hours of treatment, whereas for root extracts, the skin moisturization rate decreased from 30% immediately after treatment to 5% after 2 hours of treatment. It is considered to be usable.

The present invention will be described in more detail by illustrating the preparation of the following formulations by introducing each of the above-mentioned cosmetically effective root-derived extracts into a solubilizer type and an emulsifier type, but the present invention is not limited to these preparation examples.
