[0027] [Experimental Example 1] Procollagen Biosynthesis Ability

[0028] Fibroblasts isolated from human skin were implanted into 24 wells at a rate of 106 per well, and cultured until the growth reached 90%. After culturing it in serum-free medium for 24 hours, three single substances and four mixtures of Gynura procumbens, Gynura pseudochina and Averrhoa bilimbi were dissolved in serum-free medium treated at a concentration of 100ppm, and in CO 2 Cultured in the incubator for 24 hours. These supernatants were taken, and the increase or decrease of procollagen was verified with (I) type procollagen (Procollagen type 1) Elisa kit, and the results are shown in Table 1. Experiments were carried out at concentrations in consideration of cytotoxicity, and the synthetic ability was the result of comparison with the non-treated group as 100.

[0032] [Experimental Example 2] Collagenase (MMP-1) inhibitory ability

[0033] In the experiment, 5000 cells / hole (well) of human fibroblasts were added to a 96-well plate culture device (96-well microtiter plate) containing DMEM (Dulbecco's Modified Eagle's Media) medium containing 2.5% fetal bovine serum, Cultivate until the growth is 70-80%. Then, three single substances and four mixtures of Gynura procumbens, Gynura pseudochina and Averrhoa bilimbi were treated at a concentration of 10ppm for 24 hours, and collected cell culture medium. The collected cell culture solution was used to measure the degree of collagenase production using a commercially available collagenase detection device (Amersham pharmacia, USA, Catalog #: RPN2610). First, the collected cell culture solution was added to a 96-well plate (96-well plate) uniformly coated with the collagenase antibody once, and an antigen-antibody reaction was carried out in an incubator for 3 hours. After 3 hours, the c...

[0039] [Experimental Example 3] Evaluation of Melanin Production Inhibition Ability Using Melan-a Cells

[0040] Each of the produced extracts and mixtures was used as a test substance, and 2×10 4 Cells / well (final volume 3ml), to 96-well plate (MTT method) with 2×10 3 Cells / well (final volume: 200ul) were added, and cultured for 24 hours in a 37°C, 5% CO2 incubator (MCO-20AIC, Sanyo). After culturing, the medium was removed, and a DMEM medium containing 10% FBS, 2uM α-MSH (Melanocyte stimulating hormone) and 2mM theophylline was used as a new medium, and added to the medium The test substance was added and the treatment was carried out every day for 3 days. On day 5, the medium cultured in the 6-well plate was removed, and the pellet was recovered by treating with 0.25% trypsin-EDTA (Sigma Chemical Co.) solution, and moved to a 1.5 ml test tube (tube) for The supernatant was removed by centrifugation at 10000 rpm for 10 minutes. After drying the obtained pellet at 60°C, 1...

Abstract

The present invention relates to cosmetic material compositions for skin whitening or skin anti-aging containing Averrhoa bilimbi extract as an active ingredient. The active ingredient of each composition further contains selectively at least one selected from the group consisting of Gynura procumbens extract and Gynura pseudochina extract. According to the cosmetic material composition of the present invention, skin function can be effectively improved without skin irritation through, for example, enhancing skin whitening or preventing the aging of skin.

Description

technical field [0001] The present invention relates to a cosmetic composition for skin whitening or skin anti-aging. Background technique [0002] Cell damage stimuli, such as ultraviolet rays, environmental pollutants, and rapid temperature changes, can induce various biochemical changes in cells and cause cell damage responses. Among them, increasing skin whitening and preventing skin aging play the most important role in improving skin function. [0003] Regarding skin whitening, when the skin is exposed to ultraviolet rays, it will synthesize and release melanin, which determines the skin color of a person, and induce hyperpigmentation such as moles, freckles, spots, etc., and bring about unfavorable cosmetic consequences. The synthesis process of melanin is, first, an enzyme called tyrosinase (tyrosinase) uses intracellular tyrosine (tyrosine) as a substrate to generate dopaquinone (dopaquinone), and dopaquinone undergoes autooxidative reaction and enzyme The reactio...
