[0049] Preparation Example 1: Preparation of Flower Extract of Magnolias

[0050] 100 g of dried flowers of Magnolias (purchased from Kyung Dong Market, Korea) were added to 1.0 L of 70% ethanol (ethanol: water = 7: 3), and extracted at room temperature for 3 days. The extracted solution was filtered, and the filtrate was concentrated under vacuum to obtain a dried extract (extraction rate: 7.8 g / 100 g). The dried extract was dissolved in 30% 1,3-butanediol solution to a concentration of 1% (w / v), and then filtered. The obtained extracts were then used in the experiments of the present invention.

[0051] Preparation Example 2: Preparation of the Whole Plant Extract of Magnolias

[0052] Add 100 g of dried whole plant of Magnolia magnolia (purchased from Kyung Dong Market, Korea) into 1.0 L of 70% ethanol (ethanol:water=7:3), and extract at room temperature for 3 days. The extracted solution was filtered, and the filtrate was concentrated under vacuum to obtain a dry extract (extraction rate: 7.0 g / 100 g). The dried extract was dissolved in 30% 1,3-butanediol solution to a concentration of 1% (w / v), and then filtered. The obtained extracts were then used in the experiments of the present invention.

[0053] Experimental example 1: Inhibition of keratinocyte cell death caused by ultraviolet rays

[0054] When keratinocytes are irradiated with ultraviolet rays, active oxygen is generated in the cells. To artificially induce this phenomenon, normal human keratinocytes, namely Hacat cells (Korea Cell Line Bank), were seeded into each well of a 48-well microplate at a density of 1×10 4 cells / well, and cultured at 37° C. for 24 hours in DMEM medium (Sigma, USA). The cultured cells were irradiated with ultraviolet rays (UVB), and then the magnolia extract of Preparation Example 1 was added to the cell culture in each well at concentrations of 0.1, 0.5, 1.0 and 2.0% (v / v). After 24 hours, cell viability was analyzed by MTT assay.

Abstract

Disclosed herein is a cosmetic composition for preventing photoaging, containing an extract of Magnolia sieboldii as an active ingredient. Also disclosed is a cosmetic composition for reducing skin wrinkles containing an extract of Magnolia sieboldii as an active ingredient. The extract of Magnolia sieboldii can protect the skin against UV lights and skin damage by suppressing skin cell death and cell DNA damage, and can reduce skin wrinkles by promoting the biosynthesis of collagen and suppressing the synthesis of collagenases. Also, the cosmetic composition containing the extract of Magnolia sieboldii has an excellent effect of inhibiting skin damage caused by UV lights, and an excellent effect of reducing skin wrinkles.

Description

technical field [0001] The present invention relates to a cosmetic composition containing Magnolia sieboldii extract as an active ingredient, and more particularly, to a cosmetic composition containing Magnolia sieboldii extract for protecting the skin from ultraviolet Cosmetic composition of magnolia extract, thus used to protect DNA and skin cells from UV damage, promote collagen biosynthesis and inhibit collagenase biosynthesis. Background technique [0002] For most people, the skin is exposed to sunlight during the growth stage, but the skin tissue gradually changes with age, so various phenomena occur due to sunlight, including rough skin, wrinkles, dark spots, poor skin tone, diarrhea, Telangiectasia, dark spots, purpura, easy bruising, atrophy, fibrosis, discolored sites, and in severe cases premalignant and malignant tumors. [0003] Ultraviolet rays are divided into UVA, UVB and UVC ranges, of which only UVA and UVB can reach the surface of the earth, and UVC is f...
