Description

[0001] The present invention relates to a composition for improving skin comprising a herbal extract,

The present invention relates to a composition containing as an active ingredient a complex herbal extract which is safe when applied to skin and has excellent skin improving effect.

The skin is an important body that is responsible for various physiological functions such as barrier function, body temperature control function, excretion function, which protects the human body from the external environment and prevents the internal moisture and useful components from flowing out. However, due to the following reasons, the activity of skin cells may deteriorate and the skin condition may deteriorate.

Collagen and elastin present in the dermis of the skin perform functions such as mechanical rigidity of the skin, resistance of the connective tissue, maintenance of the cohesion of the tissue, and support of the cell adhesion, and have a great influence on the constituents of the skin. It is known that such collagen is reduced by photoaging due to stress, aging, or ultraviolet irradiation, while elastin is known to be distorted in its three-dimensional structure by the degrading enzyme elastase, which is activated after exposure to ultraviolet light. As a result, the skin tissue is loosened and the elasticity is lost.

When the cell function of the epidermis is lowered, the metabolism is not smooth and the exfoliation does not occur well, and when the ultraviolet rays are received in a state where the keratin is overly accumulated, the elasticity is lowered and wrinkles are generated. If the skin is not formed on the epidermis, moisture and sebum secretion are reduced, and the skin becomes dry and wrinkles are formed.

When the skin receives ultraviolet rays, melanin is synthesized to protect the skin. The synthesized melanin is transferred to the keratinocytes of the skin through the melanoma. This keratinocyte turns over over a period of 28 days. Therefore, the melanin produced is generally lost by the keratinocyte periodically for 28 days. However, when the skin cell cycle is not properly controlled by the stress, skin aging, etc., keratinocytes do not fall out in the presentation period and the pigment such as spots, freckles, Calm occurs.

In the skin, sebum, sweat and cosmetic ingredients are decomposed into substances that are toxic to the skin by the fungus, which can cause skin irritation and inflammation. In addition, skin irritation caused by ultraviolet rays increases the production of nitrogen monoxide (NO), which is an inflammation mediator, to cause skin troubles. The production of nitrogen monoxide is mostly caused by iNOS, and it is known that iNOS is rapidly induced by stimulation such as LPS and cytokine to produce excessive NO.

A reactive oxygen species (ROS), also known as a toxic oxygen species, is a cell-generated toxic substance produced by physiological actions such as respiration and is constantly produced and extinguished, with 3-5% in normal conditions . These reactive oxygen species are free radicals such as superoxide radicals (O2-) and hydroxyl radicals (HO +), which are chemically bound to atoms or molecules that are not paired with the outermost electron orbits Highly unstable and highly reactive) or in the form of compounds with paired electrons such as hydrogen peroxide (H ₂ O ₂ ) or singlet radicals. Active oxygen species have the advantage of biologically protecting bacteria in the physiological system, but generally cause oxidation in vivo, causing harmful effects that cause disease. It has been reported that these reactive oxygen species attack biological molecules and damage cells and tissues and cause various diseases related to aging and various diseases.

Research has been continued to suppress the skin aging caused by various factors as described above, to improve whitening, wrinkles, elasticity or trouble, and to develop a substance having an antioxidative effect.

Materials having the above-mentioned effects are widely distributed in the natural world, and they have been mainly used as raw materials for foods, cosmetics, medicines and the like using materials derived from plants. However, the substances derived from such natural substances are not effective enough to be used in large quantities in order to obtain a meaningful effect, resulting in toxicity and price increase.

In order to solve the problems of such natural materials, the development of chemically synthesized materials has continued. Although they have a merit that they exert a superior effect even when used in a small amount compared to a natural substance, their use is limited due to a fatal problem that can cause large and small side effects to the human body.

Accordingly, it is inevitable to develop a substance derived from a natural product and having stability, while exhibiting an excellent effect on skin improvement.

DMSO was used as a negative control group, and albutin was used as a positive control group.

Specifically, the sample was added to the medium to a final concentration of 100 ppm, arbutin was added to the medium to be 100 ppm, and melanoma cells were cultured for 3 days. Cells were then trypsinized, detached from the culture, centrifuged, and then melanin was extracted. The removed cells were incubated with 1 ml of sodium hydroxide solution (1N concentration), boiled for 10 minutes to dissolve melanin, and the absorbance was measured at 400 nm using a spectrophotometer to measure the amount of melanin produced.

The amount of melanin was measured by an absorbance of 1 × 10 ⁶ cells per unit cell, and the total amount of melanin relative to the control group was calculated as inhibition rate (%). The results are shown in Table 2 below. And the average value.

As can be seen from the results of Table 2 above, the mixed extract showed excellent melanin total amount reduction effect and was found to be useful for whitening purposes.

<Experimental Example 3> Anti-inflammatory effect

In order to confirm the anti-inflammatory effect and the improvement of skin trouble, nitric oxide (NO) production inhibition experiment was performed by GRIESS method using RAW264.7 cell line (ATCC number: CRL-2278).

Specifically, RAW264.7 cells, macrophages of mice, were subcultured several times, placed in 24-well plates so as to enter 3x10 ⁵ wells into one well, and cultured for 24 hours. Subsequently, the cell culture medium containing the sample was replaced with a final concentration of 10 ppm. At this time, L-NMMA (L-NG-Monomethylarginine), which is an inhibitor of NO production, was treated together as a positive control and cultured for 30 minutes. Lipopolysaccharide (LPS) 100 μl of the supernatant was transferred to a 96-well plate, 100 μl of GRIESS solution was added thereto, and the reaction was allowed to proceed at room temperature for 10 minutes. The absorbance at 540 nm was measured to determine the NO inhibitory effect. Calculated using Equation (2) and shown in Table 3 below. Experiments were performed three times each and expressed as average values.

NO production inhibition rate (%) = {(absorbance of negative control - absorbance of each extract) / absorbance of negative control} x 100

sample NO production inhibition rate (%) Control group (DMSO, 10 ppm) - L-NMMA (positive control, 10 ppm) 41.02 Example 1 (10 ppm) 37.24 Example 2 36.19 Example 3 39.72 Example 4 38.71 Example 5 42.82 Example 6 37.51 Example 7 31.18 Example 8 47.81

As can be seen from the results of Table 3, it was found that the mixed extracts exhibited excellent activity as a natural substance when compared with the representative anti-inflammatory drug L-NMMA, although the relative activity was somewhat low.

<Experimental Example 4> Promoting collagen synthesis

The sample was added to the culture medium of human - derived fibroblasts to confirm the promoting effect of type I collagen synthesis at the cellular level. The synthesized collagen was quantitated using a PICP EIA kit (Procollagen Type I C-Peptide Enzyme Immuno Assay Kit). In order to measure the amount of collagen synthesis, the sample was added to a fibroblast culture medium (DMEM medium) at a final concentration of 10 ppm and cultured for 48 hours. The culture broth was taken and the degree of type 1 collagen synthesis was measured at each concentration using a PICP EIA kit And measured at 450 nm using a spectrophotometer.

For the comparison of the effects, the degree of collagen synthesis was measured in the same manner for the samples in which the culture medium of the untreated fibroblasts (negative control) and vitamin C (positive control) were added to a final concentration of 52.85 / / ml. The increase rate of collagen production was calculated by the ratio of relative collagen production to the negative control, and the results are shown in Table 4 below.

sample Type 1 collagen production (ng / ml) Growth rate (%) Negative control group 150.2 - Positive control (vitamin C) 246.8 64.3 Example 1 (10 ppm) 234.7 56.26 Example 2 174.2 15.98 Example 3 177.7 18.31 Example 4 197.3 31.36 Example 5 226.9 51.07 Example 6 196.4 30.76 Example 7 184.2 22.64 Example 8 246.7 64.25

As can be seen from the results in Table 4, the collagen synthesis was increased when the mixed extract was treated, and the collagen synthesis effect was comparable to that of vitamin C, which is generally known to induce collagen synthesis.

<Experimental Example 5> Elastase activity inhibitory effect

The activity inhibitory effect of Elastase, an enzyme that degrades elastin, was confirmed as follows.

Elastase used Elastase from human leukocyte cells and MeOSuc-Ala-Ala-Pro-Val-pNA as synthetic substrate for Elastase. The buffer solution used was 100 mM Tris (pH 7.5) solution. Finally, 0.2 mU was used for the ELASTASES using a buffer solution. In addition, the synthetic substrate of Elastase was diluted with buffer solution to make a final concentration of 0.5 mM by making a 100 mM solution using DMSO. At this time, the positive control group was set to contain 10 ppm of quercetin, which is known as an inhibitor of Elastinase. Ellazease inhibition candidates were added to give a final concentration of 10 ppm. The reaction was carried out in a 96-well plate and allowed to react at room temperature for 20 minutes. Absorbance was measured at 405 nm using a spectrophotometer at intervals of 1 minute, and the slope of the absorbance versus time was determined as the activity of the enzyme. Ella stasis inhibition rates were calculated as follows.

&Quot; (3) &quot;

The inhibition rate of elastase was calculated using Equation (3) and shown in Table 5 below.

sample Enzyme activity Inhibition rate (%) Example 1 (10 ppm) 5.7 45.19 Example 2 4.9 52.88 Example 3 6.1 41.35 Example 4 4.9 52.88 Example 5 6.1 41.35 Example 6 5.9 43.27 Example 7 5.4 48.08 Example 8 3.7 64.42 The positive control (Quercetin, 10 ppm) 3.5 66.35 The control (DMSO, 20 ppm) 10.4 -

As can be seen from the results in Table 5, when the mixed extract was treated, it was found that it exhibited a better inhibitory effect on elastase activity, though the effect was somewhat weaker than that of the positive control. Therefore, it was found that the mixed extract can be used for skin regeneration and wrinkle improvement.

<Experimental Example 6> Antioxidant effect

The free radical scavenging ability of the mixed extract was measured by the 1,1-diphenyl-2-picryl hydrazyl (DPPH) method (Blois, Nature 181, 1190, 1958). DPPH is a relatively stable free radical, which shows maximum absorption at 517 nm in the presence of radicals and loses its absorbance when radicals are eliminated. DPPH was purchased from Sigma, and dissolved in methyl alcohol at a concentration of 0.15 mM.

First, 100 쨉 l of the mixed extract or the positive control, vitamin C, was added to each well of a 96-well plate. 100 쨉 l of DPPH solution was added thereto, and the mixture was allowed to stand at room temperature for 30 minutes, and the absorbance at 517 nm was measured using a microplate reader (BioTek EL-340).

IC ₅₀ represents the concentration of the extract when the absorbance of the sample is half the absorbance of the control group. The results are shown in Table 6 below. This experiment was repeated 3 times.

sample IC ₅₀ (% w / v) Control group 0.0025 Positive control (vitamin C) 0.0005 Example 1 0.0009 Example 2 0.0011 Example 3 0.0010 Example 4 0.0012 Example 5 0.0011 Example 6 0.0027 Example 7 0.0009 Example 8 0.0005
