[Production Example 1]
10 kg of a 50 wt% aqueous ethanol solution was added to 1 kg of a dried pulverized product of the genus Capsicum and soaked at room temperature for 7 days. The extract was collected by filtration, and after removing the solvent, an extract of the plant belonging to the genus Carina was obtained.

[Production Example 2]
Nine liters of water was added to 1 kg of the dried pulverized product of the genus Euphorbiaceae and extracted by refluxing at 90 ° C. for 6 hours. The extract was collected by filtration, and after removing the solvent, an extract of the plant belonging to the genus Carina was obtained.

[Production Example 3]
Nine liters of methanol was added to 1 kg of a dried pulverized product of the genus Eucommia and immersed for 7 days at room temperature. The extract was collected by filtration, and after removing the solvent, an extract of the plant belonging to the genus Carina was obtained.

[Production Example 4]

  First, it shows about the test for evaluating each effect | action of the genus Echinacea. In each test, the whole plant of Androsase eresia extracted according to Production Example 1 was used.

<Evaluation of cell activation in dermal fibroblasts>
The evaluation was performed according to the following procedure. Normal human dermal fibroblasts were seeded in a 96-well microplate at 2.0 × 10 ⁴ cells per well. The seeding medium used was Dulbecco's modified Eagle medium (DMEM) supplemented with 1% fetal bovine serum. After culturing for 24 hours, the culture medium was replaced with a test medium to which a sample having an arbitrary concentration was added, and further cultured for 48 hours. Next, the medium containing 400 μg / mL of 3- (4,5-dimethyl-2-thiazolyl) -2,5-diphenyltetrazolium bromide (MTT) was exchanged and cultured for 2 hours. Formazan generated by the opening of the tetrazolium ring was removed. Extraction was performed with 2-propanol, and absorbance at 550 nm was measured with a microplate reader. At the same time, the absorbance at 650 nm was measured as turbidity, and the cell activation effect was evaluated by the difference between the two measured values. The evaluation results are shown in Table 1 as relative values with the cell activation effect in the blank with no sample as 100. In addition, ** in the table represents a significance probability of less than 1% (P <0.01) with respect to the significance probability P value in the t test.

  As is clear from Table 1, a significant dermal fibroblast activation effect was observed in the medium supplemented with the extract of the genus Capsicum.

<Evaluation of cell activation in epidermal cells>
The evaluation was performed according to the following procedure. Normal human epidermal cells were seeded in a 96-well microplate at 2.0 × 10 ⁴ cells per well. As a seeding medium, commercially available Humdia-KG2 manufactured by Kurabo Industries Co., Ltd. was used. After culturing for 24 hours, the culture medium was replaced with the test medium to which the sample was added, and further cultured for 24 hours. Subsequently, the medium containing 100 μg / mL of 3- (4,5-dimethyl-2-thiazolyl) -2,5-diphenyltetrazolium bromide (MTT) was exchanged and cultured for 2 hours. Extraction was performed with 2-propanol, and absorbance at 550 nm was measured with a microplate reader. At the same time, the absorbance at 650 nm was measured as turbidity, and the cell activation effect was evaluated by the difference between the two measured values. The evaluation results are shown in Table 2 as relative values when the cell activation effect when the sample is not added is 100.

  As is clear from Table 2, a significant epidermal cell activation effect was observed in the medium supplemented with the extract of the plant of the genus Capsicum.

<Evaluation of Tyrosinase Activity Inhibitory Action in Epidermal Melanocytes>
The evaluation was performed according to the following procedure. Normal human epidermal melanocytes manufactured by Kurabo Industries Co., Ltd. were seeded in a 96-well microplate so as to be 3.0 × 10 ⁴ cells per well. As a seeding medium, Medium154S manufactured by Kurabo Industries Co., Ltd. was used. After 24 hours, the medium was replaced with a medium to which each concentration of sample was added, and further cultured for 48 hours. Next, 75 μL of 1 wt% Triton-X-containing phosphate buffer was exchanged to completely lyse the cells, and 50 μL was used as a crude enzyme solution. To the crude enzyme solution, 50 μL of a 0.05 wt% L-dopa-containing phosphate buffer as a substrate was added and allowed to stand at 37 ° C. for 2 hours. The absorbance at 405 nm was measured immediately after the addition of the substrate and at the end of the reaction with a microplate reader, and the amount of produced dopamelanin was calculated. The tyrosinase activity inhibition rate of the sample is shown in Table 3 as a relative value to the tyrosinase activity inhibition rate in the blank with no sample added.

  As is clear from Table 3, when a medium supplemented with an extract of the genus Euphorbia was used, an excellent inhibitory effect on tyrosinase activity was observed.

<Evaluation of antioxidant effect by scavenging DPPH radical>
The evaluation was performed according to the following procedure. 100 μL of a solution of the extract of the genus Euphorbiaceae diluted to an arbitrary concentration with a 50 wt% aqueous ethanol solution was added to a 96-well microplate. Next, 100 μL of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution prepared with ethanol to a concentration of 0.2 mM was added to a 96-well microplate. The mixture was left in the dark with stirring, and the absorbance at 516 nm was measured after 24 hours. When the absorbance of the blank with no sample added was (A) and the absorbance when the sample was added was (B), the value of formula (1) was defined as the radical elimination rate. The evaluation results are shown in Table 4.
Formula (1) {1- (B) / (A)} × 100 (%)
