[0040] Test Example 2. Melanin Production Inhibition Evaluation Test (1) Culture of B16 cells B16 cells (mouse melanoma cells) were cultured in DMEM (Dulbecco's modified Eagle's medium (Sigma-Aldrich, St Louis, MO, USA)) containing 10% FBS (fetal bovine serum), 100 units / ml penicillin, and 100 μg / ml streptomycin (Wako, Osaka, Japan) at 5% CO2 and a temperature of 37°C. (2) Test solution treatment Using the same culture method as in (1) above, 5 × 10⁶ cells were cultured in a 6-well multiplate. 4B16 cells were seeded at a concentration of 1 cell / well. 24 hours later, a mixed solution of 3-isobutyl-1-methylxanthine (IBMX) as a melanin inducer, the test solution, and 2 mL of 10% FBS, 100 units / ml penicillin, and 100 μg / ml streptomycin-containing DMEM was prepared in each well, replacing the culture medium. The cells were then cultured at 5% CO2 and 37°C. The test solutions prepared were 1.0% (concentration as solution) of extracts from Production Examples 1-3 and their comparative control (extract from Comparative Production Example 1), and 0.5% (concentration as solution) of extracts from Production Examples 4 and 5 and their comparative control (extract from Comparative Production Example 1). Furthermore, a control (-IBMX) was set up when the culture medium was cultured without IBMX, and instead of the test solution, 0.75% or 0.5% 1,3-butylene glycol (BG) was added. In addition, a control (+IBMX) was set up when IBMX was added, and 0.75% or 0.5% BG was added instead of the test solution. (3) Measurement of melanin content After 72 hours of sample processing, the culture medium was removed, and each well was washed with 2 mL of PBS. Then, 50 μL of 1% TritonX-100 (SIGMA) and 250 μL of 1N NaOH were added in that order, mixed thoroughly, and collected in 1.5 mL tubes. The collected tubes were incubated at 98°C for 30 minutes to prepare cell lysates. The lysates were thoroughly mixed, and 80 μL / well was added to a 96-well multiplate. The absorbance at 405 nm was measured using a microplate reader (ARVO). TM X3). (4) Measurement of protein content The cell lysate prepared in (3) above was used with the Pierce BCA Protein Assay Kit (Thermo Scientific) according to the manual. The absorbance at 560 nm was measured using a microplate reader (ARVO). TM X3). (5) Evaluation of melanin production Melanin and protein levels were calculated using the method described above, and melanin production was evaluated from the melanin / protein ratio. The evaluation values ​​were calculated as relative values ​​with the control (-IBMX) set to 100.

[0041] The results of Test Example 2 are shown in Figures 1 and 2. As shown in Figures 1 and 2, it was confirmed that the extracts from Production Examples 1 to 5 exhibited significantly superior melanin production inhibitory effects compared to the extract from Comparative Production Example 1.

[0042] Test Example 3. Whitening evaluation test of ginsenosides Rg3, Rg5, Rb1, and Rg1. As test solutions, solutions of ginsenosides Rg3, Rg5, Rb1, and Rg1 were used instead of the production examples 1-5 and comparative production example 1 of Test Example 2. Dimethyl sulfoxide (DMSO) was used as the solvent to dissolve IBMX. A control (-IBMX) was set up when the culture medium was cultured with DMSO instead of ginsenosides, without adding IBMX. Furthermore, a control (+IBMX) was set up when the culture medium was cultured with IBMX and DMSO instead of the test solution. The final concentration of DMSO was adjusted to 0.1%.

[0043] The results of Test Example 3 are shown in Figures 3 and 4. As shown in Figure 3, Rg3 and Rg5 exerted a melanin production inhibitory effect at low concentrations, while as shown in Figure 4, Rb1 and Rg1 were confirmed to promote melanin production.

[0044] Test Example 4: Evaluation Test of Cell Damage Repair Caused by Ultraviolet Radiation (1)Cell (HaCaT) culture HaCaT cells (human keratinocyte cells) were cultured in DMEM (Dulbecco's modified Eagle's medium (Sigma-Aldrich, St Louis, MO, USA)) containing 5% FBS (fetal bovine serum), 100 units / mL penicillin, and 100 μg / mL streptomycin (Wako, Osaka, Japan) at 5% CO2 and a temperature of 37°C. (2) Test solution treatment Using the same culture method as in (1) above, 1 × 10⁶ cells were cultured in a 6-well multiplate. 5 HaCaT cells were seeded at a concentration of 1 cell / well. 24 hours later, a mixed solution of the test solution and 2 mL of 10% FBS, 100 units / ml penicillin, and 100 μg / mL streptomycin-containing DMEM was prepared and added to each well, replacing the culture medium. Cells were then cultured at 5% CO2 and 37°C. For the evaluation of cell viability repair, preparations 1-3 and their comparison (extract from comparative preparation 1) were prepared to a concentration of 0.5% (solution concentration). For the evaluation of intracellular glutathione production promotion, extracts from preparations 1, 2, and 5 and their comparison (extract from comparative preparation 1) were prepared to a concentration of 1.0% (solution concentration). A control was set where cells were cultured in a culture medium with 0.25% or 1.0% BG added instead of the test solution. (3) UV-B treatment (HaCaT cells) Five hours after treatment with the test solution, the samples were exposed to UV-B (60 mJ) using a UVB irradiator (TL20W / 12RS lamp, Dermaray 200; Muranaka). UV intensity was measured using an ultraviolet radiation sensor (UVX-31; TGK). After UV-B exposure, the samples were cultured at 5% CO2 and 37°C. A control group (UV-) that was not irradiated with UV-B was set up for comparison. (4) Cell viability evaluation (HaCaT cells) The procedure was performed using the Cell Counting Kit-8 (CCK8; Dojindo) according to the manual. The following modifications were made from the manual: After 24 hours of UV-B exposure, the culture medium was removed, and the CCK8 solution was added to each well. The mixture was incubated at 5% CO2 and 37°C for 1 hour. The CCK8 solution was collected in a 96-well plate, and the absorbance at 450 nm was measured using a microplate reader (ARVO). TM X3). The evaluation value was calculated as a relative value with the control (UV-) without UV-B irradiation set to 100. (5-1) Glutathione (GSH) measurement (HaCaT cells) After 24 hours of UV-B exposure, the culture medium was removed, and each well was washed with 2 mL of PBS. 300 μL of 0.05% Trypsin-EDTA (Gibco) was added, and the mixture was incubated at 5% CO2, 37°C, for 5 minutes. 300 μL of DMEM was added, and the mixture was collected in a 1.5 mL tube. 500 μL of PBS was then added to each well, and the mixture was collected in the same tube. Centrifuge (2000 rpm, 3 minutes) and the supernatant was removed. 1 mL of PBS was added, and the mixture was centrifuged (2000 rpm, 3 minutes) and the supernatant was removed. 250 μL of 0.5% Triton-X100 was added, and the mixture was thoroughly vortexed and sonicated. Centrifuged (13200 rpm, 10 minutes) and the supernatant was collected. The collected supernatant was subjected to GSSG / GSH Quantification using the Dojindo Quantification Kit according to the manual. The absorbance at 405 nm was measured using a microplate reader (ARVO TM X3). (5-2) Protein level measurement (HaCaT cells) The supernatant collected in the "Glutathione Measurement" described above was analyzed using the Pierce BCA Protein Assay Kit (Thermo Scientific) according to the manual. The absorbance at 560 nm was measured using a microplate reader (ARVO). TM X3). (5-3) Glutathione level evaluation (HaCaT cells) Glutathione (GSH) and protein levels were calculated using the method described above, and glutathione levels were evaluated from the glutathione / protein ratio. The evaluation values ​​were calculated as relative values ​​with the control group (UV-) without UV-B irradiation set to 100.

[0045] The results of Test Example 4 are shown in Figures 5 to 7. As shown in Figure 5, the extract according to the present invention was confirmed to exhibit a remarkable effect in repairing cells damaged by ultraviolet light compared to Comparative Production Example 1. Furthermore, as shown in Figures 6 and 7, the extract according to the present invention was also confirmed to have a remarkable effect in restoring the amount of intracellular glutathione that has decreased due to ultraviolet irradiation, compared to Comparative Production Example 1.

[0046] Test Example 5. Evaluation Test of Fibroblast Activation Effect Human dermal-derived fibroblasts NB1RGB were placed in 1 × 10⁶ wells of Eagle Minimum Essential Medium containing 0.5% NCS in a 96-well microplate. 4 Cells were seeded per well and pre-cultured for 1 day under conditions of 37°C and 5.0% CO2. Then, extracts from production examples 4 and 5 and comparative production example 1 were added to the culture medium as sample solutions to a concentration of 0.5% (as solution), and cultured for a further 3 days under the same conditions. Next, the medium was removed, 0.03% MTT was added, and the culture was held at 37°C for 1 hour. The resulting formazan was extracted with isopropanol, and the MTT value was measured at a wavelength of 570-630 nm using a microplate reader (Model 680, Bio-Rad). The same procedure was performed for the control case (no sample added) where PBS(-) was added instead of the sample solution. The relative value of the MTT value with each sample added to the MTT value obtained here was calculated and expressed as the fibroblast MTT activity rate (%). In addition, to confirm that the test system was functioning correctly, the same test was performed when 100 mM glucose was added as a positive control instead of the sample solution.

[0047] The results of Test Example 5 are shown in Figure 8. As shown in Figure 8, it was confirmed that the extract according to the present invention exhibits a significant fibroblast-activating effect compared to Comparative Production Example 1.
