The present invention relates to a composition containing plant extracts, and more particularly, to a composition for skin whitening, skin regeneration, elasticity improvement, wrinkle suppression, inflammation suppression, skin soothing, skin moisturizing, oxidation inhibition, or bacterial inhibition.
Most people want to have fair skin. Skin color is genetically determined according to the concentration and distribution of melanin in the skin, but skin color is also affected by environmental factors such as ultraviolet rays and physiological factors such as fatigue and stress. Melanin is produced through a non-enzymatic oxidation reaction after tyrosine, a type of amino acid, is converted to dopa and dopaquinone by action of a tyrosinase enzyme. As such, the pathway by which melanin is produced is known, but the previous step of the step in which tyrosinase acts, that is, the mechanism of inducing melanin synthesis, is still unknown.
Examples of general whitening ingredients comprise substances that inhibit tyrosinase enzyme activity, such as kojic acid and arbutin, hydroquinone, vitamin-C (L-ascorbic acid) and derivatives thereof, and various plants extracts. The above-described whitening ingredients may lighten skin tone by inhibiting synthesis of a melanin pigment, thereby realizing skin whitening. In addition, the whitening ingredients may alleviate skin hyperpigmentation, such as melasma or freckles, caused by ultraviolet rays, hormones, or heredity. However, when the whitening ingredients are applied to the skin, usage thereof may be limited due to safety issues such as irritation and redness. In addition, in some cases, since the effect of the whitening ingredients is insignificant, a substantial effect may not be expected for the whitening ingredients.
Meanwhile, collagen is a major matrix protein produced by fibroblasts of the skin and is present in the extracellular matrix. Collagen is responsible for maintaining the mechanical strength of the skin, imparting resistance and bonding strength to the connective tissues, maintaining cell adhesion, and inducing cell division and differentiation (in growth of an organism or wound healing). Collagen decreases with age and photoaging caused by UV irradiation, which is known to be closely related to formation of wrinkles in the skin. Also, in recent years, as extensive research on skin aging progresses, new functions of collagen in the skin are being revealed.
Active ingredients that promote collagen synthesis and exhibit anti-wrinkle effects are known. For example, retinoic acid, a transforming growth factor (TGF) [Non-Patent Document 1], an animal placenta-derived protein [Patent Document 1], betulinic acid [Patent Document 2], and chlorella extracts [Patent Document 3, 4] are known as collagen synthesis promoting substances. However, when the active ingredients are applied to the skin, usage thereof may be limited due to safety issues such as irritation and redness. In addition, in some cases, since the effect of the active ingredients is insignificant, the effect of improving the skin function by promoting synthesis of collagen in the skin may be substantially insignificant.
Meanwhile, inflammation is an immune response of the human body in response to a wound or disease, and ultraviolet rays or oxidative stress due to reactive oxygen species or free radicals activates inflammatory factors to cause various diseases and aging of the skin. Vasoactive polypeptides such as kinin, plasmin, and complements play a role in vasodilation, vasoconstriction, and chemotaxis. In addition, lymphokines, such as interleukin-6 (IL-6), and arachidonic acid are responsible for inflammatory responses. Arachidonic acid is converted to prostaglandins and leukotrienes, which are inflammatory mediators, through two pathways associated with cyclooxygenase and lipooxygenase, and mediates various inflammatory responses.
Anti-inflammatory agents serve to eliminate inflammation by removing inflammatory sources and reducing biological responses and symptoms. To date, substances used for anti-inflammatory purposes comprise non-steroidal substances such as flufenamic acid, ibuprofen, benzydamine, and indomethacin and steroidal substances such as prednisolone and dexamethasone. In addition, allantoin, azene, hydrocortisone, and the like are known to have an anti-inflammatory effect. However, usage thereof may be limited due to skin safety issues, and the effect of alleviating inflammation by these substances may he insignificant.
Meanwhile, hyaluronic acid is a type of glycosaminoglycan and is a chain-shaped polymeric polysaccharide in which glucuronic acid and N-acetylglucosamine residues are repeatedly linked. Hyaluronic acid has high viscosity and elasticity and can form a gel by combining with a large amount of water. Hyaluronic acid is a major component of the extracellular matrix and is involved in water retention, maintenance of intercellular spacing, and storage and diffusion of cell growth factors and nutrients. In addition, hyaluronic acid is known to be involved in cell division and differentiation, cell migration, and the like.
According to previous reports, more than 50% of hyaluronic acid present in the body of a mammal is distributed in the skin, particularly between epidermal cells and in the connective tissues of the dermis. In addition, hyaluronic acid is mainly synthesized by keratinocytes and fibroblasts. It has been reported that the amount of hyaluronic acid in human skin decreases with aging and decrease in hyaluronic acid in the skin is considered to be one of the direct causes of decrease in skin elasticity and moisture content due to aging (BiochemBiophysActa 279, 265-275; Carbohydr Res 159, 127-136; Int J Dermatol 33, 119-122). In addition, hyaluronic acid is known to be involved in maintaining the structure of the stratum corneum and maintaining skin barrier function (J CosmetDermatol. 2007 Jun. 6(2), 75-82).
However, hyaluronic acid having the above effects is not effectively absorbed into the skin due to high molecular weight thereof. In addition, a method of injecting hyaluronic acid into the skin through injection is currently being implemented, but this method may cause great irritation. Compared to this method, a method that promotes synthesis of hyaluronic acid in skin cells is more effective. Therefore, research on a method for increasing production of hyaluronic acid in the human body is being actively conducted, but remarkable research results are not yet known.
Meanwhile, reactive oxygen species introduced into the human body from the outside or reactive oxygen species generated in the human body may accelerate aging of the human body or cause cancers. Accordingly, development and research on antioxidants that inhibit oxidation induced by reactive oxygen species are being actively conducted. Antioxidants are widely distributed in the animal and plant kingdoms, and many phenolic compounds, flavonoids, tocopherols, vitamin C, and selenium in fruits and vegetables are known as antioxidants. However, when naturally occurring antioxidants are applied to the skin, it is difficult to obtain sufficient antioxidant effects. Accordingly, although synthetic antioxidants with excellent antioxidant power and low price are widely used, use thereof is limited due to safety concerns such as side effects in the human body.
Meanwhile, with development of transportation, people around the world are moving actively. Accordingly, various infectious diseases and new diseases are rapidly spreading. In the past, the indiscriminate use of antibacterial substances has conferred resistance to various microorganisms, which threatens mankind. In particular, for preservation of perishable products (e.g., cosmetics, pharmaceuticals, or food), there is continuous demand for substances with antibacterial properties for direct cosmetic improvement or therapy against microorganisms that may adversely affect the body.
Pesticides may be broadly divided into fungicides, pesticides, herbicides, and growth regulators. To prevent damage to crops by viruses or microorganisms, fungicides are used. Excessive use of cheap and powerful synthetic antibacterial substances in agriculture has threatened our table. Various antibacterial substances are also used in household products that come into direct contact with the human body. In this case, most of these antibacterial substances are manufactured using inexpensive chemical components. Unfortunately, based on scientific evidence, long-term use of most of these antibacterial substances may be harmful to the human body.
Preservatives, antibacterial substances approved for human use, are added to many products such as food, pharmaceuticals, daily necessities, and cosmetics widely used in our daily life to prevent change in physical properties and preserve the products for a certain period of time. In particular, in the case of products that are in frequent contact with the hand or the human body, such as cosmetics, microorganisms may be introduced from the outside, and the quality of the product may be changed by these microorganisms. In particular, when products used around the eyes are contaminated, eye diseases may be induced. In the United States in the 1920s, there was a case in which a consumer went blind after using mascara contaminated with microorganisms. Accordingly, technologies for securing consumer safety and preserving product quality by preventing contamination of the products by microorganisms have been continuously developed.
Naturally produced substances are also used as the preservatives, but most of the preservatives are chemically synthesized artificial substances. Existing preservatives, such as parabens, are known to be safe and are widely used in household products, cosmetics, and pharmaceuticals. However, paraben preservatives also have problems such as skin allergies (Andrea Counti et al., Contact Dermatitis, 1997, 37;35-36), potential as environmental hormones (Edwin et al., Toxicology and applied pharmacology, 1998, 153;12-19), and generation of resistant bacteria.
Most of natural active substances used as preservatives have not been commercialized due to problems such as coloration, reduced stability, a narrow antibacterial spectrum, and formulation limitation. Only a few natural active substances are being commercialized, such as hinokitiol, which is a cypress extract, magnolol, which is a magnolia extract, and DF-100, which is a grapefruit extract. Accordingly, there is an increasing need for natural antibacterial substances that can replace existing synthetic chemical antibacterial substances. In particular, it is necessary to develop a natural antibacterial substance that reduces the side effects of antibacterial agents and has a wide antibacterial spectrum and formulation stability.
The present inventors confirmed that 109 plant extracts reduced the total amount of melanin and tyrosinase activity in melanocytes of the skin to obtain a skin whitening effect, promoted skin regeneration and improve skin elasticity or reduce skin wrinkles by promoting collagen synthesis and inhibiting collagenase activity in the fibroblasts of the skin, obtained an anti-inflammatory or a skin soothing effect by inhibiting NO generation, obtained a moisturizing effect by increasing the amount of moisture in the skin by promoting production of hyaluronic acid in fibroblasts, obtained an antioxidant effect by scavenging free radicals, and obtained a broad antibacterial effect against various bacteria. Based on these results, the present inventors conducted further studies to complete the present invention.
Therefore, the present invention has been made in view of the above problems, and it is one object of the present invention to provide a composition for skin whitening, skin regeneration, elasticity improvement, wrinkle suppression, inflammation suppression, skin soothing, skin moisturizing, oxidation inhibition, or bacterial inhibition comprising, as active ingredients, one or more plant extracts selected from the group consisting of Island thistle (scientific name: Cirsium nipponicum (Maxim.)

In the present invention, the term “anti-wrinkle effect” refers to suppressing or inhibiting formation of wrinkles on the skin or alleviating already formed wrinkles.
In the present invention, the term “anti-inflammatory effect” refers to suppressing inflammation. Inflammation is a kind of defense mechanism of a living tissue against a certain stimulus and refers to a complex lesion associated with three responses: tissue deterioration, circulatory disturbance and exudation, and tissue proliferation. More specifically, inflammation is part of innate immunity, and as in other animals, human innate immunity recognizes patterns on the surface of cells that are specific to pathogens. Phagocytes recognize cells having such a surface as foreign cells and attack pathogens. When pathogens break through the body's physical barriers, an inflammatory response occurs. The inflammatory response is a non-specific defense action that creates a hostile environment for microorganisms that invade a wound site. In the inflammatory response, when a wound is formed or an external infectious agent enters the body, white blood cells responsible for the initial stage of the immune response penetrate the site of infection and express cytokines. Accordingly, the expression level of intracellular cytokines is an indicator of inflammatory response activation. Examples of skin diseases related to inflammation include atopic dermatitis, psoriasis, erythematous diseases triggered by radiation, chemicals, burns, etc., acid burn, bullous dermatosis, lichenoid-type diseases, itching caused by allergies, seborrheic eczema, rosacea, pemphigus vulgaris, erythema multiforme, erythema nodosum, balanitis, inflammatory hair loss such as alopecia areata, and cutaneous T-cell lymphoma, but the present invention is not limited thereto. In addition to an anti-inflammatory effect, a cosmetic having an anti-inflammatory effect has a skin soothing effect.
In the present invention, the term “moisturizing effect” refers to increasing the moisture content of the skin, reducing the roughness of the skin, and keeping the skin moist. The “moisturizing effect” is related to maintaining the flexibility of the skin by supplying moisture to the skin or blocking evaporation of moisture from the skin and maintaining a smooth surface by inducing uniform exfoliation of dead skin cells. When the skin moisturizing effect is increased, skin elasticity may be increased, and skin wrinkles may be reduced.
In the present invention, the term “antioxidant effect” refers to inhibiting oxidation of cells by highly reactive free radicals or reactive oxygen species (ROS) that are generated by oxidative stress due to intracellular metabolism or ultraviolet rays. The “antioxidant effect” is associated with reducing cell damage by removing free radicals or reactive oxygen species.
In the present invention, the term “antibacterial effect” refers to ability to resist bacteria, and comprises all mechanisms performed to protect the human body from microorganisms such as bacteria, fungi, and yeast. In addition, in the present invention, the “antibacterial effect” may mean inhibiting growth of bacteria in the oral cavity, and the bacteria may be bacteria such as the Streptococcus genus and the Porphyromonas genus. Specifically, the bacteria may be selected from the group consisting of Streptococcus mutans, Streptococcus sanguinis, Streptococcus sanguinis, Streptococcus salivarius subsp. thermophilus, and Porphyromonas gingivalis.
In the present invention, the term “effective amount” or “comprising as an active ingredient” means an amount of extracts capable of exhibiting a whitening effect, promoting regeneration of damaged skin, reducing wrinkles, inhibiting inflammation, exhibiting a moisturizing effect, inhibiting or alleviating cell oxidation, or exhibiting a broad antibacterial effect against various bacteria.

Hereinafter, embodiments of the present invention will be described in detail. However, the following examples are only illustrative of the present invention, and the content of the present invention is not limited to the following examples.
A 70% aqueous ethanol solution was added to the whole plant, roots, sterns, leaves, fruits, flowers, shoots, branches, bark, sap, bulbils, or seeds of each of plants 1 to 112. At this time, the 70% aqueous ethanol solution was added in a volume corresponding to 20 times the mass of each plant tissue. Then, extraction was performed at room temperature for 3 days, and then filtration under reduced pressure was performed. Then, the filtered extracts were concentrated and dried using a rotary evaporator (Buchi, Switzerland) to prepare plant extracts.
After a sample was added to the culture medium of B-16 mouse melanoma cells, a whitening effect was confirmed by measuring the total amount of melanin at the cellular level (Lotan R., Lotan D. Cancer Res. 40:3345-3350, 1980), Before the experiment, toxicity evaluation was performed on mouse melanoma cells to select a concentration without toxicity, and then whitening evaluation was performed at the concentration.
The sample was added to the culture medium so that the final concentration is the treatment concentration shown in the table below. As a control, arbutin was added to the culture medium at a concentration of 200 ppm. B-16 melanoma cells treated with the sample or arbutin were cultured for 3 days.
Thereafter, the cells were removed from a culture vessel and centrifuged, 1 ml of sodium hydroxide solution (1N concentration) was added to the centrifuged cell pellet, heating was performed at 80° C. for 10 minutes to dissolve melanin, and using a spectrophotometer, absorbance at 400 nm was measured to measure the amount of melanin produced.
The amount of melanin was determined according to absorbance per unit cell number (1×106 cells). In addition, based on a non-addition control group, the relative total amount of melanin in the experimental group treated with each sample was calculated as inhibition rate (%), and the results are summarized in the table below.
Each sample was added to the culture medium of human-derived fibroblasts to confirm the effect of promoting synthesis of type I collagen at the cellular level. Measurement of synthesized collagen was quantified using a Procollagen Type I C-Peptide Enzyme Immuno Assay KIT (PICP ETA kit). To measure the amount of synthesized collagen, each sample was added to a fibroblast culture medium (DMEM culture medium). After cell culture for 48 hours, the culture medium was taken, and the degree of synthesis of type I collagen at each concentration was measured at 450 nm using a spectrophotometer using the PICP ETA kit.
For comparison of the effects, a collagen synthesis level was measured in the same manner for the culture medium of untreated fibroblasts (negative control) and a sample (positive control) to which TGFb was added to a final concentration of 10 ppb. A collagen production increase rate was calculated as the ratio of relative collagen production to the negative control group, and the results are shown in the table below.
To check the anti-inflammatory effect and skin trouble alleviation effect of each sample, an experiment was conducted to evaluate inhibition of nitric oxide (NO) formation by the GRIESS method using the RAW264.7 cell line (ATCC number: CRL-2278).
Specifically, RAW264.7 cells, which are macrophages of mice, were subcultured several times, and the cells were seeded at a cell density of 3×105 cells per well in a 24-well plate, followed by cell culture for 24 hours. Then, the final concentration was replaced with the diluted cell medium as shown in the table below. At this time, as a positive control, the cells were treated with L-NG-monomethylarginine (L-NMMA), a NO-production inhibitor, to a final concentration of 5 ppm and cultured for 30 minutes. Then, the cells were treated with lipopolysaccharide (LPS) as a stimulus at a concentration of 1 μg/ml and cultured for 24 hours. 100 μl of the supernatant was transferred to a 96-well plate, 100 μl of a GRIESS solution was added thereto, and then reaction was performed at room temperature for 10 minutes. Then, absorbance at 540 tun was measured, and the NO inhibitory effect of each sample was determined based on the absorbance, and the results are shown in the table below
Human-derived fibroblasts (human dermal fibroblasts) cultured in a DMEM culture medium containing 10% fetal bovine serum at a cell density of 1×105 cells/mL, and 500 μl of the cell culture medium was added to each well of a 24-well plate. After incubation for 18 hours, the samples were diluted with a DMEM culture medium without fetal bovine serum, and each sample was added at the following concentrations. As a positive control, epidermal growth factor (EGF), which is known to promote hyaluronic acid production, was added at a concentration of 10 ppb. After incubation for 24 hours, the cell culture medium was recovered, and the concentration of hyaluronic acid was measured using a Hyaluronan ELISA kit (R&D Systems).
In addition, based on the hyaluronic acid concentration (100%) of a non-addition control group, the hyaluronic acid concentrations of the experimental groups treated with each sample were quantified, and the results are shown in the following table.
To confirm antioxidant activity, free radical scavenging activity was measured using DPPH. DPPH was purchased from Sigma Co., Ltd. (USA). First, a standard DPPH ethanol solution with a concentration of 1.5 mM (0.06 mg/ml) was prepared. Then, ethanol was added to each extract and ascorbic acid as a reference material, which is known as an antioxidant, to prepare samples at a concentration of 0.1%, and serial dilution was performed. Then, the sample and the standard DPPH solution were added in the same ratio and stirred, followed by reaction at 37° C. for 30 minutes. Then, absorbance was measured at 517 nm. At this time, addition of ethanol instead of the sample was used as a control. Free radical scavenging ability was measured by calculating IC50, which is half maximal inhibitory concentration, and the results are shown in the following table. IC50 is a general method of expressing free radical scavenging ability as the concentration of ascorbic acid and extract required to remove 50% of free radicals of a non-addition control group.
MICs were measured for fermented cultures of Staphylococcus aureus and Aspergillus niger.
MIC measurement for Staphylococcus aureus was performed using Mueller Hinton broth, an optimal culture medium, at a bacterial concentration of 106 CFU/mL at 37° C. for 24 hours. MIC measurement for Aspergillus niger was performed using potato dextrose broth at a bacterial concentration of 105 CFU/mL at 30° C. for 48 hours. The serial dilution method was used for both bacteria, and the MIC of fermentation culture was confirmed by visually comparing the turbidity between wells after the incubation was completed.
The minimum inhibitory concentration of each extract was expressed as % (w/v), and MIC (%) in each table means % (w/v) unless otherwise stated.
Antibacterial activity experiment was performed to confirm the preventive or therapeutic effect on dental caries and periodontitis of each sample. To confirm the effect of inhibiting the growth of oral pathogens, an antibacterial activity test was conducted by using the paper disc test method using Streptococcus mutans, a representative bacterium that causes dental caries, and Porphyromonas gingivalis, a representative bacterium that causes periodontal diseases.
After increasing the activity of each oral pathogen under the optimal culture conditions shown in the table below, each pathogen was cultured in an optimal medium for about 4 to 6 hours so that the turbidity of the culture medium was set to Macfarland turbidity No. 0.5 (1.5×108), and then 0.1 ml of each oral pathogen was spread evenly on a plate medium. Thereafter, each sample was added at a concentration of 10 mg/disc and left for 1 hour for absorption drying. Then, each oral pathogen was cultured at the optimum temperature for 24 to 48 hours, and then the size (diameter, mm) of a growth inhibition ring was measured.
