[0036] Preparation Example 1: Preparation of Active Substances from Forsythia

[0037] 5 L of 95% ethanol was added to 1 kg of forsythia (fruit of Forsythia korean) powder washed with purified water, dried and powdered, and reflux stirring was performed. Then, by filtration and concentration, 33.2 g of a concentrate were obtained. Next, n-hexane was added, and a degreasing process (fractionation and separation) was performed to obtain 19.3 g of a concentrate. The concentrate was separated using cation exchange resin Diaion HP-20 (column 25 x 100 cm) by adding water and methanol, continuously increasing methanol concentration (10% methanol, 20% methanol, etc.). Of the fractions, the methanol fraction was concentrated to 60-80% to obtain 3.5 g of a concentrate, which was dissolved in methanol. Separated by LH-20 and MPLC, 0.63g of arctiin was obtained, and observed by NMR and mass spectrometry. Other active substances of forsythia, such as arctigenin, materesinol, pedicel, fo...

[0038] Preparation Example 2: Preparation of a mixture of arctiin and arctigenin

[0039] Arctiin was extracted and prepared from Forsythia in the same manner as described in Preparation Example 1, mixed with arctigenin purchased from Sigma at a weight ratio of 1:3 to 3:1, and prepared at a high concentration (4,000ppm) Soluble in 1,3-butanediol.

[0040] Experimental Example 1: Inhibition of Melanin Synthesis by Active Substances of Forsythia

[0041] α-MSH used in the melanin synthesis inhibition experiment was dissolved in 10% DMSO (dimethyl sulfoxide), and used as a 1 mM solution. B-16 melanoma (ATCC CRL 6323) cell line (from mice) was inoculated into DMEM medium containing 4.5g / L glucose, 10% serum and 1% antibiotics, and placed in a 75cm 2 In cell culture flasks at 37°C, 5% CO 2 Train next time. Subculture melanoma cell lines in 75cm 2 Cell culture flasks were cultured for 24 hours and treated with 0.05% trypsin containing 0.02% EDTA. Then, detach the cells and inoculate in 75cm 2 Cell culture flasks were further cultured for 6 hours. Here, the number of cells is 1×10 7 cells / flask. Then, melanocyte-stimulating hormone was diluted in DMEM medium to a final concentration of 100 μg / ml. Next, each of arctiin, arctigenin, materesinol, oleanolic acid, betulinic acid, rutin, and ursolic acid was diluted in DMEM m...

Abstract

Present Invention relates to a skin whitening cosmetic composition comprising arctiin, arctigenin or a mixture thereof as an active ingredient. The disclosed composition can control or inhibit the synthesis of melanin by acting on a melanin synthesis route of alpha-MSH secreted by UV, and thus show an excellent whitening effect compared to a conventional skin whitening cosmetic. Also, the composition has high formulation stability and low skin irritation.

Description

technical field [0001] The present invention relates to a skin whitening cosmetic composition containing arctiin, arctigenin or a mixture thereof as an active ingredient. Background technique [0002] Everyone always wants to have white and fine skin. Generally speaking, the color of human skin, hair, eyes, etc. depends on melanin, carotene, heme, etc. In particular, melanin is also a major determinant of human skin color. In other words, skin color depends on the amount, nature and distribution of melanin. Pigments in human skin or hair play a role in protecting the skin or hair from the harmful effects of sunlight, especially UV rays. For example, a person who lacks this pigment is very sensitive to sunlight, suffers from burns, and therefore has a high chance of developing skin cancer even at a young age. Short-wavelength (290-320nm) ultraviolet rays and carcinogens form harmful free radicals such as oxygen free radicals in the skin, and thus such oxygen free radicals...
