Wrinkles are the result of aging of the skin, and aging skin is the aggregate of the natural changes associated with the process of aging. Skin aging is divided into two categories, physiological aging, which indicates a change in skin function, structure, or shape related to age, and photoaging by ultraviolet rays.

As the skin ages, the changes in the dermis appear remarkably, and dermis atrophy after 70 years is a representative aging phenomenon. Changes in the dermis are caused by changes in substances with large molecular weight in the extracellular matrix due to a decrease in the number of fibroblasts and their ability to synthesize. Specific changes include separation of collagen bundles, reduced point polysaccharide synthesis, decreased collagen and elastic fiber counts and diameters, grinding collagen and elastic fibers, and expansion of blood vessels. Generally, among the various factors such as skin moisture content, collagen content, and ability to immunize the external environment, the biggest influence on wrinkle formation is collagen, a collagen degrading enzyme that reduces collagen production and collagen content. It is the expression level and activity of genease. The effect of sakchocho extract on collagen and collagenase enzyme was not revealed, but through this experiment, sachocho extract increased collagen synthesis and inhibited collagenase enzyme.

 Human skin color is determined by the concentration and distribution of melanin inside the skin. Melanin pigment produced by melanocytes of human skin is a phenolic polymer having a complex form of black pigment and protein, and plays an important role in preventing skin damage caused by ultraviolet rays. In melanin biosynthesis, the action of tyrosinase in melanocytes is reported to be the most important. Tyrosinase is a type of amino acid tyrosine (DOPA) and dopaquinone (dopaquinone) plays a key role in the skin blackening process.

Hormonal imbalances are aggravating due to environmental pollution and automobile exhaust. As a result, the incidence of hair loss increases, the age of incidence decreases, and the immunity of the skin immune system is caused, resulting in various skin diseases such as atopy and psoriasis.

Example 4: Determination of melanin production inhibitory effect

B16 melanoma cells (Korea Cell Line Bank) were used to measure the inhibitory effect of melanin production by saccharin extract and compared with the inhibitory effect of melanin production by arbutin known to inhibit melanin production.

This experiment was performed in 6-well plates using murine melanoma (B-16 F10) cells (Korea Cell Line Bank) in DMEM medium containing 10% fetal bovine serum (FBS). Inoculated at 1 × 10 ⁵ per cell and incubated under 5% CO ₂ and 37 ° C. until cells were at least about 80% attached to the bottom of the well. The medium was then removed and the sample was replaced with medium diluted to the appropriate concentration and incubated for 3 days under 5% CO ₂ and 37 ° C. The concentration ranges of sakchocho extract were determined to be 1 ppm, 10 ppm and 100 ppm without cytotoxicity. The cells from which the medium was removed were washed with PBS (phosphate buffered saline) and treated with trypsin to recover the cells. The recovered cells were measured by using a hematocytometer (Tiefe Depth Profondeur 0.100 mm, Paul Marienfeld GmbH & Co. KG, Germany), the cell number was measured, centrifuged at 5,000 to 10,000 rpm for 10 minutes, and then the upper layer. The liquid was removed to obtain pellets. The cell pellet was dried at 60 ° C., and 100 ml of 1 M sodium hydroxide solution containing 10% DMSO was added to obtain intracellular melanin in a 60 ° C. thermostat. This was measured by absorbance at 490 nm with a microplate reader (Bio-Tek ELx8081U, United States of America) to determine the amount of melanin per cell. The results are shown in Table 4 below.

sample Treatment Concentration (ppm) Inhibition rate of intracellular tyrosinase activity (%) Arbutin 100 25 Sarangcho Extract 10 15 50 24 100 37

As shown in Table 5, it was found that the potted vinegar extract has a higher inhibition rate of intracellular tyrosinase than arbutin. In addition, it can be seen that the degree of inhibition of tyrosinase activity of sachocho extract is concentration-dependent.

Example 6 Evaluation of Whitening Effect at Animal Level

Similar to humans, the whitening effect of vinegar extract was measured using brown guinea pigs (Tortoiseshell guinea pigs; known as pigmentation caused by ultraviolet rays).

In order to cause pigmentation due to ultraviolet rays (UV) in the brown guinea pigs, a light shielding aluminum foil having a square window of 3 × 3 cm ² is adhered to the skin from which the hairs of the brown guinea pigs are removed, and then SE lamp ( Ultraviolet rays were irradiated with a wavelength of 290-320 nm (Toshiba) (total amount of irradiation energy = 1350 mJ / cm ² ). After UV irradiation, the aluminum foil was peeled off and a sample (Sarangchoe extract and arbutin) was applied in the following manner. Pigmentation appeared 2-3 days after UV irradiation and reached a peak after about 2 weeks, from which each sample was applied.

The number of coatings was continued once or twice a day for 50 days. Samples were dissolved and diluted using a specific solvent (Propylene Glycol: Ethanol: Water = 5: 3: 2 mixed solvent), and a control site was prepared using a cotton swab and necessarily applying the solvent to other sites. In this case, the cumulative stimulus was observed along with the effect determination.

The effect was determined by measuring the degree of black and white of the skin using a color difference meter (CR2002 chromameter, Minolta, Japan), the results are shown in Table 6 below. L ^* A ^* B ^* color system is used to display color, and L ^* value was used as an index in this invention. L ^* value was calibrated with a standard whiteboard, and L ^* value was measured 5 times or more at one site, and pigmentation was equalized. The difference (ΔL ^* ) of the skin color at the start of application and at the end of application was determined and the effect was determined using this value. The results are shown in Table 6 below.

△ L ^* = L ^* value after 00 days application - L ^* value of the coating start date

Comparing the ΔL ^* value with respect to the sample application site and the control site, the effect of the whitening material can be seen.

sample Treatment Concentration (%) Whitening effect (△ L) Sarangcho Extract 0.01 0.27 0.1 0.33 Arbutin 1.0 0.31 Control - 0.24

As shown in Table 6, sakchocho extract showed a superior whitening effect than arbutin, and cumulative irritation was not observed during the test application of the test substance, and thus safety was also excellent.

Example 7 Safety Confirmation Experiment

In order to confirm that the sakchocho extract extract is safe to human skin, skin safety verification experiment was performed. To this end, a cumulative skin irritation test was performed.

Formulated with 1%, 5%, and 10% of sachochoen extract, respectively, based on squalene, a total of nine 24-hour cumulative patches were applied to the upper forearm every other day for 30 healthy adults. It was measured whether the love vinegar extract stimulates the skin. The patching method used a fin chamber (Finn chamber, Epitest Ltd, Finland). 15 µl of each of the external skin preparations was added dropwise to the chamber, followed by patching. The degree of response to the skin each time was scored using Equation 2 below, and the results are shown in Table 7 below.

Average responsiveness = [[{(response x responsiveness) / (total number of subjects x highest score (4 points))}] x 100] ÷ number of tests (9)

In the reactivity, ± gives 1 point, + gives 2 points, and ++ gives 4 points, which are judged as safe compositions when the average reactivity is less than 3.

Test substance Number of subjects with response Average reactivity 1 week 2 weeks 3 weeks Primary Secondary 3rd 4th 5th 6th 7th 8th 9th ± + + + ± + + + ± + + + ± + + + ± + + + ± + + + ± + + + ± + + + ± + + + Control group (squalene) One - - 0 - - --- --- --- --- --- --- --- 0.09 Sarangcho Extract (1%) [Test Group 1] 0 - - 0 - - --- --- --- --- --- --- --- 0.00 Sarangcho Extract (5%) [Test Group 2] 0 - - 0 - - --- --- --- --- --- --- --- 0.00 Sarangcho Extract (10%) [Test Group 3] 2 - - 0 - - --- --- --- --- --- --- --- 0.18

In Table 7, the number of persons corresponding to ±, +, and ++ in test groups 1, 2, and 3 was 0, 0, and 2, respectively, and the average reactivity was 0.00, 0.00, and 0.18, respectively. Therefore, since the average reactivity was less than 3, it was judged that Sasacho extract was a safe substance for human skin that did not show a distinct cumulative stimulation pattern.

Example 8: Evaluation of anti-inflammatory efficacy

In order to examine the anti-inflammatory effect, COX (cyclooxygenase) activity inhibitory activity was performed according to a conventional method on THP-1 cells (Korea Cell Line Bank). COX activity was measured according to Method in Enzymology 43: 9 (1994) published by FJ Van de Ouderaaa and Muytenhek. The COX assay cultured THP-1 cell line and then dispensed the cells into 24-well plates. Adjust the reaction volume to 500 μl per well, add 2 μl of sample compound dissolved in lipopolysaccharide (LPS) (1 μg / ml) (Sigma) and the solvents shown in Table 5 below, and then 24-48 hours. Incubated under the same conditions. After 24-48 hours, add 1 µl of calcium ionophore (Sigma) and [1-14C] arachidonic acid (in EtOH, 0.1 µCi / ml, Sigma) to each well and incubate for 10 minutes under the same conditions. It was. After incubation, citric acid was added to each well and shaken to adjust the pH to 3.5. 500 μl of each culture solution was aliquoted into a microcentrifuge tube, and 700 μl of ethyl acetate was added thereto, followed by shaking extraction for 10 minutes. 500 µl of ethyl acetate layer was taken and concentrated for 20 minutes using a speed vacuum dryer, 20 µl of the concentrated residue was dissolved in ethyl acetate, and then applied to an TLC plate with an authentic standard. Radioactivity bands were identified by authentic eicosanoid standards, and the radioactivity of the identified bands was measured using a BAS 2000 bio-imaging analyzer (Fuji, Japan).

sample COX activity (%) LPS (1 μg / ml) 100 LPS (1 μg / ml) + saengcho extract (1 ppm) 88 LPS (1 ug / ml) + saengcho extract (10 ppm) 74 LPS (1 ug / ml) + saengcho extract (50 ppm) 60

As shown in Table 8, it can be seen that the sakchocho extract effectively inhibits the activity of COX in a concentration-dependent manner. It can be seen that it can exhibit the inhibitory efficacy.

Example 9: Antioxidant Effect

DPPH (1,1-diphenyl-2-picrylhydrazyl) (Sigma) is a colored radical that can directly identify the radical removal ability of a sample by color change. First, 20 μl of the sample dissolved in the solvent was put into a 96 well plate, and 180 μl of 200 μM DPPH solution was added thereto, followed by incubation at room temperature for 30 minutes. The amount of DPPH remaining was determined by absorbance measurement at 540 nm. Antioxidant activity of the sakchocho extract is shown in Table 9 below. Briefly, the effect was judged the presence or absence of antioxidant function by observing the free radical removal rate by the sample.

sample Treatment Concentration (ppm) Free radical scavenging rate (%) Sarangcho Extract 10 24 50 77 100 85

As shown in Table 9, it can be seen that the sakchocho extract has an antioxidant effect in a concentration-dependent manner.

Example 10 Anti-Obesity Effect

Obesity inhibition test was generally carried out by the following method using a well-known animal. The results are shown in Table 10 below.

The method for measuring obesity inhibitory activity is as follows:

Crj: 7 week old ICR male mice (Higgs River, Japan) were pre-cultured for 1 week and used in experiments with 7 groups of 1 animals. Animals are kept in a constant temperature room set at a temperature of 23 ± 1 ° C, a humidity of 55 ± 5% and an illumination time of 12 hours / day, using Rabo MR (manufactured by Nippon Agricultural Co., Ltd.) for feeding, and freely ingesting water. It was made. Sasacho extract was prepared in liposome formulation (dissolved in 5% lecithin) to 0.1% and 1%. Each sample solution was adjusted to a concentration of 0.1 ml per 10 g of the mouse to doses of 1.5 g / kg and 1 g / kg. In addition, the control group was a 5% lecithin emulsion. Mice were fasted from the day before administration and were forcibly administered once the next day. The test period was 2 weeks and body weight and general symptoms were measured and observed.
