Skin diseases such as atopy are increasing due to climatic or environmental factors such as fine dust, dust, and the like. In addition, due to changes in the living environment, there is an increasing tendency for consumers to have various skin improving and cosmetics such as sufficient moisturizing for skin, prevention of skin damage due to ultraviolet rays, prevention of aging of skin, and the like.

Human skin aging can be caused by ultraviolet rays, stress, disease states, environmental factors, wounds, activation of free radicals as a result of age, etc. When such conditions are deepened, the antioxidant defense network existing in the living body is destroyed, And tissues to promote adult diseases and aging. More specifically, lipids, proteins, polysaccharides and nucleic acids, which are major constituents of the skin, are oxidized to destroy skin cells and tissues, resulting in skin aging. Particularly, the oxidation of protein causes the severing of excessive inflammation reaction and skin elasticity by cutting collagen, hyaluronic acid, elastin, proteoglycan, and fibronectin which are the connective tissues of skin. When this becomes worse, mutation by DNA mutation, Resulting in a decline in immune function.

On the other hand, various skin-beauty-related products for preventing skin aging mainly use processed chemicals, which are irritating to the skin and cause side effects that may damage the skin.

Therefore, technical researches on a cosmetic composition which can minimize the use of chemical substances and which are friendly to skin using natural materials and help to improve the skin have been actively conducted.

There have been attempts to apply food extracts to cosmetic compositions for the time being, but the use of skin extracts has been poor due to poor spreadability on the skin and the preference is low due to the inability of the skin extract to be suitable for skin care. In addition, it has not been easy for the useful components of the food extract to be absorbed into the skin, so that skin improvement or cosmetic effects using the same are hardly observed, making commercialization difficult.

Therefore, it is possible to increase the preference of the food extracts such as Aronia extract to be excellent in the spreadability and feeling of heterogeneity when applied to the skin, and to effectively absorb the nutrients contained in the extract to the skin, Researches are needed to develop techniques for skin wrinkle prevention, skin care, and improvement, and to expand its application range.

Hereinafter, the present invention will be described in more detail with reference to the following examples. However, the scope of the present invention is not limited to the following examples.

(Example 1)

100 g of Aronia was refluxed with 95% ethanol at 60 캜 for 3 times, and then concentrated under reduced pressure to remove all of the solvent to obtain an extract.

The cacao nips extract, cashew nut extract and walnut extract were obtained in the same manner as in the above-mentioned method for producing astaxanthin extract.

(Example 2)

Peroxyl radical scavenging activity was determined by ORAC analysis using Kurihara et al.

ORAC assays are widely used for the analysis of antioxidant activity of various foods and biological materials such as tea, fruit, animal tissues and blood.

For the analysis, a 96-well microplate (black, flat bottom) was used to minimize fluorescence interference.

100 μL of 40 nM fluorescein dissolved in 75 mM potassium phosphate buffer (PBS, pH 7.4) was added to the plate, and 50 μL of each sample diluted in 5 mM PBS (pH 7.4) was added.

Then 50 μL of 20 mM AAPH in 75 mM PBS (pH 7.4) was added to the plate.

Water soluble vitamin E derivatives, Trolox and AAPH, were used for each analysis.

The measurement was carried out using SpectraMax (Molecular Devices, Austria), and the fluorescence analyzer was set to stabilize for 5 seconds after shaking for 10 seconds before measurement.

The 96-well microplate was set to measure fluorescence for 200 minutes at 37 ° C for 2 minutes.

Fluorescein was measured at excitation wavelength 485 nm and emission wavelength 535 nm.

The final result was calculated as the difference between the fluorescence value of the test sample and the fluorescence value of the blank. The standard curve was measured using Trolox, a water soluble vitamin E derivative of 1, 5 and 10 μM, and all results were expressed as TE (Trolox equivalents, Respectively.

Reducing capacity was analyzed using the method of Arouma et al. (Arouma I O et al., J. Agic. Food Chem., 1998).

100μM CuCl ₂ dissolved in 10mM PBS (pH 7.4) 20 μL of the solution and 80 μL of the 250 μM neocuproine solution dissolved in the same buffer were added and then 40 μL of the sample was added. After reacting at room temperature for 1 hour, 200 μL of the reaction solution was transferred to a 96-well microplate and absorbance was measured at 454 nm using an ELISA reader Respectively.

Sample blank with CuCl ₂ 10 mM PBS was used instead of the solution and the reducing capacity of the sample was expressed as the concentration of Cu ^{1 +} calculated from the absorbance using the extinction coefficient of Cu ¹⁺ / neocuproine (7.95 × 10 ³ M ^-1 cm ^-1 ).

The results of measuring the antioxidative activity of the extract in vitro by ORAC assay and reducing capacity analysis are shown in FIGS. 1 and 2.

The concentration of each of the extracts was adjusted to 0.0001%, 0.0005% and 0.001%, respectively. The weight ratio of the extracts of Aronia and cacao nymphs, the weight ratio of the Aronia extract to the walnut extract, the weight ratio of the cacao nymph extract and the walnut extract were 1: 1, The weight ratio of Aronia extract, cacao nips extract and walnut extract was adjusted to 1: 0.6: 0.4.

Higher peroxyl radical scavenging activity and reducing capacity are shown when using Aronia extract and cocoa nips extract, when using Aronia extract and walnut extract, and when using Aronia extract, Cocoa nips extract and Walnut extract. This is because the extract has an antioxidant activity that eliminates the peroxyl radical by donating hydrogen and electron to the peroxyl radical.
