[Test Example 12] Lipogenesis inhibition test

3T3-L1 cells, a fibroblast cell line of mice, were cultured in DMEM supplemented with 10% fetal bovine serum (FBS) (Dulbecco's modified eagles medium, GIBCO BRL, Life Technologies) Lt; ⁵ > cells / well in a well culture plate. After 2 days, the cells were replaced with fresh DMEM (containing 10% FBS) medium and cultured for 2 days. The cultured cells were then induced to differentiate into DMEM (containing 10% FBS) containing 1 μg / ml insulin, 0.5 mM IBMX and 0.25 μM dexamethasone, and the gensenosides F1 and caffeine After 2 days of treatment, the cells were replaced with insulin-containing DMEM and cultured for 5 days. After 5 days, the cells were replaced with normal medium (DMEM, containing 10% FBS) and cultured while observing until the cells morphologically changed into adipocytes.

In order to evaluate the inhibitory effect of ginsenoside F1 on the fat accumulation in adipocytes, S-III staining (S4136, sigma-aldrich) was carried out using 3T3-L1 adipocytes differentiated as above. The adipocytes were fixed with 4% paraformaldehyde (pH 7.2) in phosphate buffer at room temperature, washed with PBS (phsphate buffered saline), stained with SIII and then photographed and compared visually. The control group was fed with the test substance or the test substance without the reference substance, and 50 μM of caffeine was treated with another comparative group. The degree of inhibition of fat accumulation was graded by dividing the degree of staining by +++, +, +, -, which means that the degree of staining is greater toward +++. The results are shown in Table 17.

sample % Inhibition Control group +++ Comparative group + Gin Senocide F1 -

As shown in Table 17, it was found that the ginsenoside F1 used in the present invention had an effect of inhibiting lipid synthesis which is superior to caffeine, which is a known lipid synthesis inhibitor, in addition to a small amount of fat accumulated in adipocytes have. Therefore, lipid synthesis is inhibited, and sebum is reduced, so that occurrence of acne can be suppressed.

[Test Example 13] Test for improvement of acne and reduction of sebum secretion and stimulation

30 persons who had acne were divided into 3 groups of 10 persons, and subjects corresponding to each group were allowed to use the cosmetic composition prepared in Formulation Example 3 and Comparative Formulation Examples 3 to 4 for one month. Acne improvement scale is from 1 point to 5 points, 1 point is 'No', 3 points are 'Normal' and 5 points are 'Very agree'. The experimental results are shown in Table 18 below with an average score of 10 persons.

On the other hand, Comparative Formulation Example 4 containing the antibacterial activity reference material shows the effect of improving acne, but there is a fear of skin irritation for long-term use due to strong stimulus in use, but the composition according to the present invention is not stimulated appear.

[Test Example 14] Inflammation improving effect

1. Inhibitory effect of prostaglandins

The anti - inflammatory effect was evaluated by the inhibitory effect of prostaglandin production. The effect was measured on macrophages using ginsenoside F1. First, aspirin was added to the macrophage cells collected from the abdominal cavity of mice to a final concentration of 500 M to irreversibly inhibit the cyclooxygenase (COX) activity remaining in the cells. Then, the suspension was added to each well of a 96-well cell culture tube in an amount of 100 μl, followed by culturing in an incubator of 5% CO ₂ and 37 ° C for 2 hours to adhere macrophages to the surface of the container. Then, the adhered macrophages were washed three times with PBS and used for the inflammation improving effect test. RPMI medium containing 1% (w / v) of LPS was added to the cultured macrophage 5x10 ⁴ cells / ml, followed by incubation for 12 hours. Then, production of prostaglandin was induced and treated with 100 μl of ginsenoside F1 Prostaglandins were quantitated by enzyme immunoassay (ELISA).

At this time, the inhibitory activity on the production of prostaglandin in the ginsenoside F1 was determined by setting the difference of the prostaglandins produced in the LPS treated group and the untreated group to 100%, and treating the LPS and the sample together to obtain a reduced prostaglandin percentage (Inhibitory effect of prostaglandin production) is shown in Table 19 below.

Blank (BlanF1) 100% Control group (aspirin treatment group) 25.0% Gin Senocide F1 19.2%

As shown in the above Table 19, it can be seen that the effect of inhibiting the production of prostaglandin is very high even when the ginsenoside F1 is treated as in the control group treated with aspirin. Thus, it can be seen that the ginsenoside F1 of the present invention can provide an excellent inflammation improving effect.

Also, it can be seen that ginsenoside F1 inhibits the expression of prostaglandin, which is a skin inflammation factor, to prevent and improve skin troubles.

2. IL-8 production inhibitory effect

Twenty-four hours later, the cells were washed twice with PBS and replaced with serum-free F1 eratinocyte basement media (F1BM). Each of the wells was treated with the concentration of ginsenoside F1 according to the concentrations shown in the following Table 20 and reacted for 30 minutes. Then, PGSA (10 μg / ml), PGSA (50 μg / ml), PGSA (50 μg / Mu] g / ml), respectively. Here, peptidoglycan from S. aureus (PGSA ) is a peptidoglycan extracted from Staphylococcus aureus, which is a major constituent of the cell wall of Gram-positive (+) bacteria, and the cell membrane components of bacteria are known to cause inflammation, Especially in staphylococcus, about 90% of atopic patients are reported to cause secondary infection by this bacterium. LPS (lypopolysaccaride) is a major constituent of Gram negative (-) bacterial cell membrane and is known to be the main cause of inflammation.

After culturing in a 5% CO ₂ incubator at 37 ° C for 24 hours, the culture was taken and ELISA for Interleukin-8 (IL-8) was performed. The results are shown in Table 20 below. The ELISA used the experimental method of BD science.

division IL-8 secretion (pg / ml) Untreated Control (Control) 935.12 PGSA (10 [mu] g / ml) 4812.60 PGSA (50 占 퐂 / ml) 5895.08 PGSA (50 占 퐂 / ml) + LPS (1 占 퐂 / ml) 6814.91 Ginsenoside F1 (5 ppm) 1034.92 Ginsenoside F1 (25 ppm) 1189.03 Ginsenoside F1 (50 ppm) 1302.84

In Table 20, it was confirmed that ginsenoside F 1 significantly reduced and suppressed the secretion of IL-8 increased by PGSA and LPS. Therefore, it can be seen that the composition for external application for skin of the present invention can provide a superior anti-inflammatory effect by significantly reducing the secretion of IL-8 increased by PGSA and LPS.

[Test Example 15] Evaluation of itching relief

The day before the experiment, keratinocytes (cell line name: HaCaT available from ATCC) were dispensed in a 96 well plate at ⁴ × 10 ⁴ cells / well and incubated at 37 ° C. in a 5% CO ₂ incubator for 24 hours Lt; / RTI > Twenty-four hours later, the 96-well plate was washed twice with HBSS (HanF1's Balanced Salt Solution) buffer, and the reaction buffer (2 μM Fluo-4-AM, 20% pluronic acid, 2.5 mM probenecid) gave. After incubation at 37 ° C in a 5% CO ₂ incubator for 30 minutes and at room temperature for 30 minutes, the cells were treated with ginsenoside F1 at a concentration (%) as shown in Table 21, followed by washing twice with HBSS buffer.

After 10 minutes of reaction, the cells were treated with 2 U / ml trypsin or 5 μM PAR-2 active peptide (SLIGF1V) and the change in intracellular Ca ²⁺ concentration was measured for 80 seconds. Measurement of intracellular Ca ²⁺ concentration was performed using FlexStation 3 (Molecular Device, USA). The difference between the minimum value and the maximum value obtained by measuring the flex for 80 seconds after the treatment with ginsenoside F1 and 2U / ml trypsin or 5 μM PAR-2 active peptide (SLIGF1V) was obtained, The percent inhibition (%) of intracellular influx of calcium ions compared to the difference between the minimum and maximum values in the treatment of 2 U / ml trypsin or 5 μM PAR-2 active peptide (SLIGF1V) is shown in Table 21.

Ginsenoside F1 concentration Inhibition rate of intracellular influx of calcium ions (%) Trypsin (2 U / ml) PAR-2 active peptide (5 [mu] M) 0.05% 25 29 0.1% 33 38 0.5% 39 43 1.0% 47 52

As can be seen in Table 21, the influx of intracellular calcium ions by trypsin or PAR-2 activating peptide (SLIGF1V) decreases with the treatment of ginsenoside F1, and as the concentration of ginsenoside F1 increases, It was confirmed that the inflow of calcium ions was remarkably reduced. Therefore, the composition for external application for skin of the present invention can effectively provide an excellent antinociceptive effect by effectively inhibiting the itching-inducing PAR-2 activity.

[Test Example 25] Evaluation of prevention of white hair and in vitro induction of in vivo ginsenoside F1 using white algae-stimulated albumin mice

Vitiligo mice (C57bl / 6- Mitf ^mi-vit ) were purchased from The JacF1son Lab in the USA. The anti-whiplash effect test method using the mouse in which the white moth is promoted is as follows. Dorsal hairs of 12-week-old mice were removed by depilation. However, the width of the hair removal area was adjusted to be the same for each individual. From the day after the hair was pulled out, twice a day, the anti-whiplash material was applied on the hairless area. A mixture of EtOH: 1,3-BG: DW = 3: 2: 5 (volume ratio) was used as the vehicle of the anti-whiplash material. The carrier was used as a negative control, and a solution containing 50 mM of IBMX As a control group, a solution containing 2.5% of ginsenoside F1 was used as a test group. After about 3 weeks, when the difference in antibacterial effect between the substances was visually recognized, newly-emerged hairs were collected and the amount of melanin in the hair was measured. The amount of melanin in hair was measured using the protein hydrolyzing enzyme Esperase (Novozyme). Reaction buffer was prepared by dissolving Esperase in a buffer (50 mM Tris-HCl, 5 mM DTT, pH 9.3) to a concentration of 1 NPU / ml. Five milligrams of mouse hair was added to 1 ml of reaction buffer and allowed to react for 13 hours at 37 ° C with shaking at 1,000 rpm. Then, the hair and the reaction solution were separated by an instant centrifugation. The reaction solution thus obtained is placed in a 96-well plate, and the amount of melanin in the reaction solution can be measured by measuring the absorbance at a wavelength of 405 nm. The results of visual inspection and the determination of melanin in the hair when the negative control, the positive control, and the test group material were treated with the white algae-stimulated albino mouse model are shown in Table 32, Is 100, and is compared with this value.
