Description

Antioxidant, whitening, anti-wrinkle or anti-inflammatory composition containing egg yolk oil and baecho-hyang stem cells

The present invention relates to a cosmetic composition, a pharmaceutical composition or a food composition for antioxidant, whitening, anti-wrinkle or anti-inflammatory containing egg yolk oil and baecho-hyang stem cells as active ingredients.

Recently, with the improvement of living and income level, there is a lot of interest in improving the quality of life. In particular, interest in the development of bioactive substances for body diseases and metabolism, including antioxidants, as a countermeasure for aging, various inflammatory diseases, and cancer has increased (KB Kim, et al., Journal of Nutrition and Health. 50(5)) ;415-425 (2017)). In order to supply the energy required in the living body, biochemical oxidation reactions occur constantly, and reactive oxygen species (ROS), called harmful oxygen, generated during this process is the most stable form of oxygen, triplet oxygen, in the oxidation and reduction process. Singlet oxygen produced by superoxide anion, hydroxyl radical, free radical in an unstable state such as hydrogen peroxide and hydrogen peroxide (H2O2). Because it reacts easily with substances, if it is not removed from the body, oxidative stress is caused. Since this oxidative stress is linked to the inflammatory response, it induces lipid peroxidation in various metabolic processes and damages proteins, cell membranes and DNA to induce senescence and transformation of cells, leading to stroke, cancer, arteriosclerosis, Alzheimer's disease, Parkinson's disease, etc. , atherosclerosis, etc. (Valko M, et al., Int J Biochem Cell Biol. 39:44-84 (2007); and Halliwell B, et al., NY, USA. 968 (1999)). Physiological antioxidant enzymes that protect the living body by removing the generated activated carbon include superoxide dismutase (SOD), catalase, glutathione-peroxidase (GSHpx) and glutathione S -Transferase (glutathione S-transferase, GST), etc., and α-tocopherol, β-carotene, ascorbic acid and glutathione are known as small molecule antioxidants or free radical scavenging agents (Kim SM, et al. ., Life Sci. 90 (21-22); 874-882 (2012)).

A person's skin color is determined by the concentration and distribution of melanin inside the skin. Melanin is synthesized in melanocytes in the epidermal layer of the skin. In the melanosome, an organelle in melanocytes, an enzyme called tyrosinase acts on tyrosine, a type of amino acid, to activate DOPA and dopaquinone. ) and then undergoes a non-enzymatic oxidation reaction. When the synthesis of such melanin occurs excessively in the skin, the skin tone is darkened, and spots, freckles, and the like occur. Therefore, by inhibiting the tyrosinase activity in the skin and inhibiting the synthesis of melanin, not only can the skin tone be brightened to realize skin whitening, but also hyperpigmentation of the skin such as spots and freckles caused by UV rays, hormones, and genetic causes It can improve sedation.

On the other hand, the inflammatory reaction is a biological defense reaction against external physical and chemical stimuli or bacterial infection, and nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL), which are called inflammatory mediators Produces and secretes various inflammatory cytokines such as -1β, granulocyte-macrophage colony-stimulating factor (GM-CSF), and IL-6 (YC Yoo, et al., Journal of Life Science. 26(3);338-345 (2016)). In addition, by activating nuclear factor kappa B (NF-κB), an inflammatory transcription factor, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-) 2) is expressed, prostaglandin E2 (PGE2) is produced, and the secreted inflammatory cytokine activates NF-κB again to amplify the cytokine cascade and expand the inflammatory state. In particular, NO can exhibit antibacterial and antitumor effects, but when it is produced and secreted in excess due to pathological causes, it can lead to risks such as septic shock and nerve tissue damage due to excessive vasodilation (S Han, et al., Immunopharmacol. Immunotoxicol. 35;34-42 (2013)). These inflammatory cytokines and inflammatory mediators play an important role in the inflammatory process, and proper regulation of their abnormal production has been proposed as a treatment for inflammatory diseases.

Therefore, in the cosmetic field, research and development of functional cosmetics having antioxidant, whitening, anti-wrinkle or anti-inflammatory effects are being actively conducted, and in particular, research using natural substances is continued in order not to cause toxicity or irritation to the skin. .

For example, Korean Patent Registration No. 10-1952943 reports the antioxidant effect of avocado seed extract, and Korean Patent Registration No. 10-1950384 discloses skin whitening containing hair balsam extract, yellow lily extract, and rhododendron extract as active ingredients. A composition having an effect and anti-wrinkle effect has been described, and Korean Patent Registration No. 10-1949430 discloses an anti-inflammatory and anti-wrinkle effect of an extract of ginseng extract.

On the other hand, egg yolk oil is an oily extract extracted from the yolk (yolk) of a bird egg, and is called egg yolk oil, egg oil, egg oil, and the like. Egg yolk oil is known to contain lipids, vitamin A, vitamin E, linoleic acid, and the like, and lipids are known to consist of neutral lipids, phospholipids, sterols, and the like.

In addition, "Baechohyang (排草香, Agastacherugosa)" means a perennial plant belonging to the Lamiaceae family. It is an indigenous food resource that is wild or partially cultivated in the southern regions. In the present invention, the baecho fragrance by itself has little or no insecticidal effect, but when used in combination with pyrethrum, it serves as a kind of effect enhancer that maximizes the insecticidal effect possessed by the pyrethrum.

The embodiments of the present invention are provided to more completely explain the present invention to those of ordinary skill in the art.

<Example 1> Preparation of a composition comprising egg yolk oil and baechohyang stem cells

Eggs were boiled in boiling water at 100° C. for 15 minutes, the shell and egg white were removed, and the yolk was prepared. After putting 1kg of yolk in a stainless steel container and mashing it, heat it at a temperature of 100~300℃ for 5~10 minutes. Carbonized components such as ash were removed, and oily egg yolk oil was collected in a separate container. 50 g of egg yolk oil was obtained based on 1 kg of egg yolk.

In this experiment, baechohyang stem cells were used commercially available callus powder.

A composition comprising the egg yolk oil and baechohyang stem cells in a weight ratio of 2: 1 was prepared.

<Test Example 1> Measurement of antioxidant effect

(1) DPPH (1-1-diphenyl-2-picryl-hydrazyl) radical electron donating ability measurement

100 μl of DPPH solution (5x10-4 M) was added to 100 μl of the composition obtained in Example 1 for each concentration and reacted in an incubator at 25° C. for 30 minutes, and then absorbance was measured at 540 nm using a microplate counter. As controls, L-ascorbic acid and butylated hydroxyanisole were used. The electron donating ability was expressed as the absorbance decrease rate of the sample solution and the non-additive group.

As a result, the composition according to the present invention exhibited an antioxidant effect of 85.2% at a concentration of 500 μg/ml of egg yolk oil and baechohyang stem cells.

(2) Measurement of ABTS cation radical scavenging activity

7mM 2,2-azino-bis(3-ethyl-benthiazoline-6-sulfonic acid) and 2.4mM potassium persulfate were mixed and left at room temperature for 24 hours to form ABTS+ㅇ, diluted with ethanol and 100 μl of ABTS+ㅇ 100 μl of the sample was added to the flask, left for 1 minute, and absorbance was measured at 732 nm, and L-ascorbic acid was used as an experimental control. The radical scavenging ability was expressed as the concentration value of the sample required for reduction by 1/2.

As a result of ABTS + o measurement, the composition according to the present invention exhibited an antioxidant effect of 81.2% at a concentration of 50 μg/ml of egg yolk oil and baechohyang stem cells.

<Test Example 2> Measurement of whitening effect

Tyrosinase (Tyrosinase) inhibitory activity was measured according to the method of Yagi et al. In the reaction section, 0.2 mL of a substrate solution in which 10 mM L-DOPA was dissolved in 0.5 mL of 1/15 M sodium phosphate buffer (pH 6.8) and 0.2 mL of mushroom tyrosinase (110 U/mL) were added to a mixture of 0.1 mL of sample solution and reacted at 25 ° C for 2 minutes. The DOPA chrome generated in the reaction solution was measured at 475 nm. The tyrosinase inhibitory activity was expressed as the absorbance reduction rate of the group with and without the sample solution.

As a result of measuring tyrosinase inhibitory activity, egg yolk oil and baechohyang stem cells showed 76% tyrosinase inhibitory effect compared to arbutin at a concentration of 5,000 μg/ml.

<Test Example 3> Measurement of anti-inflammatory activity

Nitric oxide (NO) was measured as nitrite and nitrate in the amount of nitric oxide (NO) in the cell supernatant. Griess reagent, which is a safe form after reduction with nitrate for nitrite, was used, and 2x106 cells in a 6 well plate were washed twice with PBS when the confluence was 80% and then cultured for more than 12 hours using a serum-free medium. Next, 10 μg/ml of lipopolysaccharide (LPS) was added to all wells except for the control group and stimulated. After 2 hours, samples were treated by concentration. The amount of NO production was measured by absorbance at 540 nm after collecting the supernatant after 24 hours and reacting with griess reagent for 10 minutes. The absorbance measured when the sample was added was converted by setting the amount of NO generated in the group to which only LPS was added as 100%. Dexamethasone (Dexa) was used as a positive control.

As a result of measuring nitric oxide (NO) inhibitory activity, egg yolk oil and baechohyang stem cells showed an excellent inhibitory ability of 55% at a concentration of 50 μg/ml.

<Test Example 4> Wrinkle improvement effect measurement

(1) Elastase inhibitory activity measurement

Elastase inhibitory activity was measured as follows. Prepare egg yolk oil and baecho-hyang stem cells to a certain concentration, take 0.5 ml each in a test tube, add 0.5 ml of porcine pancreas elastase (2.5 Unit/ml) solution dissolved in 50 mM tris-HCl buffer (pH 8.6), and then add 50 mM tris- Substrate N-succinyl-(L-Ala)3-p-nitroanilide (0.5 mg/ml) dissolved in HCl buffer (pH 8.6) was added and reacted for 20 minutes to generate p-nitroanilide from the substrate was measured at 405 nm. The elastase inhibitory activity was expressed as a decrease in absorbance in the group with and without the sample solution.

Elastase is an enzyme that degrades elastin, a protein, and is a non-specific hydrolase that can degrade collagen, another important matrix protein. In the dermal tissue of the skin, collagen and elastin related to the elasticity of the skin form a network structure, and elastin is decomposed by elastase and the bond of the skin's network structure is broken. . In addition, as one of the leukocyte granulation enzymes that decompose elastin in the body, the activity of the enzyme is extremely high in abnormal tissues, which directly causes tissue destruction, causing wrinkles and loss of elasticity of the skin.

For comparison, ursolic acid (UA) was used as a positive control. As shown here, the elastase inhibitory activity increased as the concentrations of egg yolk oil and baechohyang stem cells increased, but showed insignificant activity compared to the control Ursolic acid.

(2) Collagenase inhibitory activity measurement

Collagenase inhibitory activity was measured as follows. _{That is, the reaction group was prepared by adding 4 mM CaCl 2} to 0.1 M tris-HCl buffer (pH 7.5), 4-phenylazobenzyloxycarbonyl-Pro-Leu-Gly-Pro-D-Arg (0.3 mg/ml) To a mixture of 0.25 ml of the dissolved substrate solution and 0.1 ml of the sample solution, 0.15 ml of collagenase (0.2 mg/ml) was added, left at room temperature for 20 minutes, and then 0.5 ml of 6% citric acid was added to stop the reaction, followed by ethyl acetate 1.5 ml was added to measure the absorbance at 320 nm. Collagenase inhibitory activity was expressed as a decrease in absorbance of the samples with and without the addition of the sample solution.

Collagen is mostly present in the dermal layer of the skin and accounts for about 70-80% of the total dry weight of the skin, and plays a role in supporting the skin while occupying most of the extracellular matrix. However, collagen biosynthesis is reduced by internal factors such as a decrease in cellular activity due to natural aging, and degradation is accelerated by external factors such as an increase in stress caused by various harmful environments and an increase in reactive oxygen species by sunlight. As the skin matrix is destroyed, wrinkles are formed. Collagen is reduced by age and photoaging by UV irradiation, which is known to be closely related to skin wrinkle formation, and thus the collagenase inhibitory activity of egg yolk oil and pear extract was measured. For comparison, ursolic acid (UA) was used as a positive control.

For comparison, ursolic acid (UA) was used as a positive control. As a result of measuring the collagenase inhibitory activity of egg yolk oil and baecho-hyang stem cells, it showed high collagenase inhibitory activity of 50% or more at a concentration of 500 ug/ml.
