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.

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.

Research has been continued to develop a substance that inhibits skin aging and improves whitening or trouble caused by various factors described above.

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.

< Experimental Example  1> Antialcification  effect

In order to confirm anti-glycation efficacy, the present inventors measured glycosylation inhibitory activity using L-arginine and glucose.

First, 1M L-arginine and 1M glucose were dissolved by using 1M phosphate buffer (pH 7.4), and prepared by diluting the sample to 50ppm with 1M phosphate buffer solution. 1M L-arginine and 1M phosphate buffer solution were mixed at a ratio of 1: 4, and then 80 [mu] l each was added to a 96-well plate. To each sample, 100 μl of 0.01 M aminoguanidine was added to each sample to be diluted to 50 ppm and used as a positive control. These samples were mixed well and finally glucose diluted with 1M phosphate buffer solution was added to the final concentration of glucose to 0.1 M and reacted at 70 ° C for 4 hours. The degree of saccharification was measured by measuring the absorbance of the 96-well plate at 420 nm using a spectrophotometer.

Glycation group of the following formula was an experimental group in which 1M L-arginine and 1M glucose were added to induce glycation. Absorbance was measured at 420 nm by adding 1M L-arginine and sample alone without glucose to measure the absorbance of the sample itself. The saccharide inhibitory activity can be obtained by the following formula. Experiments were performed three times each and expressed as a mean value.

< Experimental Example  2> Melanin formation inhibitory effect

In order to confirm the whitening effect through inhibition of melanin formation, a culture solution of B-16 mouse melanoma cells in rat was cultured according to the method described in Lotan R. et al. (Cancer Res. 40: 3345-3350, 1980) The total amount of melanin was measured by adding an extract. In the experiment, first the toxicity of melanoma cells in rats was evaluated and the whitening evaluation was carried out at a concentration that is not toxic. 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 the inhibition rate (%). The results are shown in Table 2 below. As shown in FIG.

< 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 each 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.
