Description

Skin external application composition for anti-aging containing Phlox subulata extract}

The present invention relates to a composition for external application for skin comprising an extract of Dianthus dianthus as an active ingredient.

Aging of the skin is a change that occurs naturally with aging, and in addition, it is caused by many external factors such as ultraviolet rays, cigarettes, dietary habits, and environmental pollution. Aging of the skin includes a decrease in apparent age, a decrease in skin texture, an increase in wrinkles, an increase in dullness, and a decrease in skin function. As the skin ages, the red color decreases, the yellow color increases, and the color tone changes, resulting in a dull skin tone. The factors of dullness are related to pigmentation of the skin, discoloration due to glycosylation or oxidation of protein, and the like.

Currently, aminoguanidine, as a protein glycosylation inhibitor, binds to Amadori products with nucleophilic hydrazine to prevent cross-linking with proteins, thereby inhibiting the production of advanced glycation end products, and is the most promising glycosylation inhibitor drug until phase 3 clinical trials. However, there are concerns about side effects related to inhibition of catalase during long-term administration, so efforts to search for new materials that inhibit protein glycosylation that are safe and have excellent efficacy have been continued. In addition, active oxygen generated in the body denatures biological proteins, and the denatured biological proteins have increased reactivity with sugar, thereby inducing a glycation reaction. According to this mechanism, active oxygen-induced oxidative stress inhibitory activity is excellent and phenolic compound-rich extracts have been actively studied until recently, but they are still insufficient to realize practical efficacy.

The purpose of the present invention for solving the above problems is to use dianthus dianthus extract to increase the effect of preventing skin aging, preventing skin wrinkles, improving skin wrinkles, improving skin tone and reducing skin pores, and is safe for the human body and has no side effects even after long-term use It is to provide a composition for external application for skin for anti-aging.

An aspect of the present invention for achieving the above object is to provide a composition for external application for skin for anti-aging comprising an extract of Dianthus dianthus as an active ingredient.

In the present invention, the dianthus extract exhibits an excellent antioxidant effect, inhibits collagen glycation and the production of advanced glycation end products (AGEs), thereby preventing skin aging, improving wrinkles, and improving skin tone It is effective in improving and reducing skin pores.

In addition, since it has safety without adverse effects on skin cells and prevents skin cell aging, it can be used as pharmaceuticals, cosmetics, personal care products, etc. for preventing skin aging, improving wrinkles, improving skin tone, and reducing skin pores.

In the present invention, Dianthus dianthus, which is an active ingredient of the anti-aging composition for external application for skin, has the following characteristics.

The ground dianthus (Phlox subulata) is a creeping rooted perennial plant of the genus Phlox subulata and is mainly cultivated for ornamental purposes. It is also called phlox grass because it blooms although it looks like grass from a distance, and the flowers are similar to dianthus and to the ground It is called ground dianthus because it spreads. It is native to the eastern United States, grows in dry sandy land, and flowers bloom from April to September, but mainly blooms in April.

In one embodiment of the present invention, the dianthus dianthus extract can inhibit skin collagen glycation and the production of advanced glycation end products (AGEs).

One of the main causes of skin aging, glycation, is the reaction between lysine or arginine, a free amino group of a protein, and the carbonyl group of a reducing sugar, resulting in Schiff base, an initial glycation product. ) to form This reaction proceeds depending on the saccharide concentration and takes place within a few hours. The resulting schiff base produces a stable amadori product through chemical rearrangement, and the reaction takes place within a few days. Amadori products accumulate in the body and form cross-links with proteins through a series of reactions such as oxidation, dehydration, condensation, retranslocation, cleavage, and cyclization, which are irreversible. When this reaction takes place for several weeks to several months, advanced glycation end products (AGEs), which are glycation products of the brown compounds finally produced, are formed. causes

In addition, when advanced glycation end products (AGEs) of brown compounds produced in the skin accumulate, they cause yellowing and discoloration of the skin and promote melanin production, which is involved in apparent aging, so suppression of glycation stress as a countermeasure against skin aging. It is important to be conscious of (antiglycation). Glycation reaction occurs more rapidly in diabetic patients with hyperglycemia than in normal people, but even in normal blood sugar, it occurs in the body as aging progresses. things, etc.

In addition, carboxymethyl lysine (CML), which is most abundant in advanced glycation end products (AGEs), is generated by oxidative degradation of glycation initial products. Type I collagen is the most abundant protein in the dermis and is a very good target for glycation. When glycation occurs in skin collagen due to glycation stress, collagen protein denaturation, CML accumulation in the dermis, and reactions such as advanced glycation end products (AGEs) and crosslinking continue, maintaining high MMP-1 (matrix metalloproteinase) protein expression It promotes collagen decomposition, which reduces the flexibility and elasticity of the skin, resulting in wrinkles.

Therefore, the dianthus extract inhibits skin collagen glycation and the production of advanced glycation end products (AGEs), thereby preventing skin aging, preventing skin wrinkles, improving skin wrinkles, improving skin tone, and improving skin pores The reduction effect is excellent.

After 48 hours of reaction, the supernatant of each well was collected and the procollagen content (pg/ml) of the supernatant was measured using a Human pro-collagen 1 alpha 1 assay kit (R&D system, DY6220-05). In order to obtain the collagen recovery rate (%) due to inhibition of collagen glycation when treated with Dianthus extract, only glyoxal was treated as a normal control group by setting the collagen content in the supernatant of the sample and the supernatant of the wells not treated with glyoxal to 100% as a normal control group. The results are shown in Table 4 by calculating the collagen production rate (%) of the group (negative control group), the sample and the glyoxal-treated group.

sample Concentration (ppm) Compared to the normal control group
Collagen production rate (%) Compared to the negative control group
Collagen production recovery rate (%) normal control group - 100 - glyoxal
(glyoxal)
0.5 mM negative control group - 68.42 0 ground dianthus
extract 10 70.81 3.49 25 76.32 11.55 50 79.25 15.82

As can be seen in Table 4, the negative control group showed a collagen production rate of 68.42% compared to the normal control group, and it was confirmed that collagen biosynthesis inhibition and collagen glycation occurred when glycation stress was induced in the cells. On the other hand, when glycation stress was induced after pretreatment with 10, 25, and 50 ppm concentrations of Dianthus dianthus extract, the collagen production rate was increased in a concentration-dependent manner compared to the negative control group, and accordingly, it was confirmed that the recovery rate of collagen production was also significantly increased. According to the above results, it was confirmed that the dianthus extract exhibited excellent skin collagen glycation inhibitory activity.

In addition, although not shown in Table 4, when 0.5 mM glyoxal was treated for 48 hours, cell viability was confirmed to be more than 90% compared to the normal control group. caused

After removing the culture medium, the cells were treated with 50 and 100 ppm dianthus extract diluted in serum-free medium and aminoguanidine hydrochloride at 10 ppm concentration, and further cultured for 24 hours. After 24 hours, glycation stress was induced in the cells by treatment with 0.5 mM glyoxal diluted in serum-free medium for 72 hours. Cells after 72 hours of reaction were washed twice with PBS buffer, RIPA lysis buffer was added, lysed at 4°C for 5 minutes, and then centrifuged at 12,000 rpm for 10 minutes. After taking the supernatant and quantifying the protein in the same way, the CML content (μg/ml) of the supernatant was measured using a CML competitive ELISA kit (Cell biolabs, STA-816). In order to confirm the degree of inhibition of intracellular CML production due to inhibition of glycation in skin fibroblasts when treated with ground dianthus extract, the CML content of the negative control group treated with only glyoxal was 100%, and the normal control group compared to the negative control group (no sample and glyoxal added) The CML production rate (%) of the dianthus extract and aminoguanidine hydrochloride treatment group was calculated and the results are shown in FIG. 2 .

As shown in FIG. 2, it was confirmed that when the dianthus extract was treated with 50 and 100 ppm, the CML production rate was inhibited by 12.38% and 38.26%, respectively, compared to the negative control group. Aminoguanidine hydrochloride showed no cytotoxicity up to 10 ppm when treated for 24 hours at each concentration, so the cells were treated with the corresponding concentration, and it was confirmed that the CML production rate was inhibited by 23.03%. At the same concentration, the degree of inhibition of intracellular CML production by aminoguanidine hydrochloride is higher than that of dianthus extract, but within the concentration range where cytotoxicity is not observed, dianthus extract inhibits CML production higher than aminoguanidine hydrochloride by up to 38.26% at 100 ppm. By showing the degree, it was confirmed that it was much safer and had an excellent effect of inhibiting skin cell glycation.
