Abstract

The present invention relates to a composition comprising a mixture of a fermented chenopodium faberi callus culture extract and a pomegranate-derived exosome, and provides a cosmetic composition having more excellent skin moisturizing, anti-inflammatory, anti-aging and wrinkle-improving effects than the use of the fermented chenopodium faberi callus culture extract or the pomegranate-derived exosome alone.

Description

Cosmetic composition comprising fermented velvet flower callus culture extract and mixture of pomegranate-derived exosomes
Technical Field
The present invention relates to a cosmetic composition comprising a fermented edelweiss callus culture extract and a mixture of exosomes derived from punica granatum, which has effects of moisturizing skin, anti-inflammatory, anti-aging or improving wrinkles.
Background
Anti-inflammatory, whitening, skin moisturizing and anti-wrinkle are always a focus of attention as a beautiful and anti-aging mark. With this concern, products for whitening, moisturizing and anti-aging skin are actively being introduced in the cosmetic market, and as consumer interest increases, demand is increasing, and related cosmetic industries are growing into high added value industries.
Recently, according to many studies, many materials have been developed which can maximize not only an anti-inflammatory effect and an effect of promoting skin moisturizing ability but also an anti-wrinkle effect by changing the activity of a collagen synthesis-related element that generates wrinkles, and the demands of research and consumers have increased.
Endoplasmic reticulum means a microcapsule having a membrane structure with a diameter of about 20nm to 5 μm, and is classified into exosomes (exosomes), exosomes (ectosomes), microbubbles (microvesicles), microparticles (microparticles), and the like according to its size and composition. Wherein exosomes are substances secreted outside cells in all living cells such as animal cells, microorganisms, plants, body fluids, etc., and are substances having a size of 50nm to 200nm as a means of intercellular communication. Exosomes consist of phospholipid bilayers resembling cell membranes, which efficiently and easily transmit corresponding signals inside the cell by transmitting proteins to the target cells, and which can complex signals because a variety of secondary metabolites and substances related to genetic information can be delivered at once. But has the disadvantages of high manufacturing cost and poor price competitiveness.
In addition, in the development of conventional cosmetic materials, plant cells cultured from velvet flowers in plant resources, adventitious root cultures, or extracts thereof are used, and fermentation processes are also performed. However, unlike these prior studies, studies on efficacy differences based on the mixing ratio of exosomes are very little.
Thus, in the present invention, it was confirmed that in the case of preparing a complex by mixing a fermented chenopodium faberi callus culture extract and a pomegranate-derived exosome, wrinkle improvement, skin moisturizing, anti-inflammatory effects can be promoted and enhanced as compared to the case of using the fermented chenopodium faberi callus culture extract or the pomegranate-derived exosome alone, thereby completing the present invention.

Problems to be solved by the invention
The present invention is directed to a cosmetic composition comprising a mixture of a fermented chenopodium faberi callus culture extract and an exosome derived from punica granatum as active ingredients, and having effects of improving skin moisture, anti-inflammatory, anti-aging and improving wrinkles.
Solution for solving the problem
In order to achieve the above-described object, the present inventors have confirmed that when a fermented velvet flower callus culture extract and a pomegranate-derived exosome are used in a mixture in a certain ratio, the results thereof show that the effects of improving wrinkles, skin moisturizing, and anti-inflammatory effects and the like can be improved, and that the effects of improving wrinkles, skin moisturizing, and anti-inflammatory effects are improved as compared to the use of a velvet flower callus culture extract or a pomegranate-derived exosome alone, thereby completing the present invention.
The present invention provides a cosmetic composition comprising a mixture of a velvet flower (Leontopodium alpinum) callus culture extract and an exosome derived from pomegranate pulp as an active ingredient.
The cosmetic composition of the present invention contains a natural extract as an active ingredient, not only has excellent biosafety, but also minimizes skin irritation. In particular, the plant cell culture extract of the velvet flower and the exosome derived from the pomegranate act on the skin at the same time, so that the synergistic effect of the plant cell culture extract and the exosome derived from the pomegranate can obviously enhance the functions of anti-inflammation, anti-aging, wrinkle improvement, skin moisture preservation and the like.
The above-mentioned mixture of fermented edelweiss callus culture extract and pomegranate-derived exosomes can be mixed in an amount of 0.1 to 10 weight% relative to the total weight of the cosmetic composition.
In addition, the above mixture can be obtained by mixing the fermented velvet flower callus culture extract and the pomegranate-derived exosomes in a weight ratio of 1:9 to 9:1, and in a specific embodiment, the present inventors confirmed that the fermented velvet flower callus culture extract and the pomegranate-derived exosomes in a weight ratio of 9:1, 7:3, 5:5, 3:7 are more excellent in wrinkle improvement, skin moisturization and anti-inflammatory effects in the case where the fermented velvet flower callus culture extract contained in the mixture is identical to or more than the pomegranate pulp-derived exosomes, and tested.
In the above-mentioned extract of the callus of the velvet flower, the term "callus" is a plant cell or an adventitious root culture, and may refer to a plant cell mass formed by division of the velvet flower plant cell.
The above-mentioned velvet flower callus culture extract may be a fermented extract obtained by inoculating a lactobacillus (lactobacillus sp.) strain.
The fermentation refers to a process of decomposing an organic substance by using enzymes possessed by a microorganism itself. The fermented metabolic substances contain various amino acids, organic acids and antioxidant substances beneficial to skin, so that skin metabolism is promoted, and skin texture is elastic and smooth. In addition, the particles become smaller through the fermentation process, so that the absorption rate is good, and the skin problem or allergic side effect can be relieved.
The above fermented extract can be prepared by the following means: the extract is naturally dried or dried by using a device such as a rotary vacuum concentrator or a freeze dryer, and the culture or extract is diluted in a solvent, preferably purified water, at a certain concentration, and then inoculated with a microorganism for fermentation, that is, lactobacillus sp, and fermented.
The lactobacillus strain may be lactobacillus pentosus (Lactobacillus pentosus), lactobacillus brevis (Lactobacillus brevis), lactobacillus plantarum (Lactobacillus plantarum), lactobacillus casei (Lactobacillus casei) or lactobacillus acidophilus (Lactobacillus acidophilus), but is not limited thereto.
The cosmetic composition of the present invention can be used for moisturizing skin, anti-inflammatory, anti-aging or improving skin wrinkles.
The term "skin moisturization" as used above means all the actions of maintaining the skin tissue steady state by properly adjusting the moisture loss (moisture evaporation) or the like of the skin. The skin moisturizing effect may be accompanied by various additional skin improving effects such as a keratolytic effect and a skin irritation reducing effect.
The term "anti-inflammatory" refers to the effect of inhibiting inflammation, and it is known that the regulation of inflammatory response is very complex, which enhances the recovery system in the organism and reduces damage. However, if the inflammatory reaction continues due to repeated tissue injury or regeneration, excessive Reactive Oxygen Species (ROS) are generated in the cells associated with inflammation, and permanent gene deformation is caused. That is, ROS are closely related to inflammatory responses that regulate various cellular actions in the body.
The above "improvement of wrinkles" refers to a phenomenon of inhibiting or preventing the skin from generating wrinkles, or relieving wrinkles that have been generated.
In addition, the present invention provides a method for preparing a mixture composed of a fermented chenopodium faberi callus culture extract and an exosome derived from punica granatum, comprising the steps of: preparing a velvet flower callus culture extract; fermenting the velvet flower callus culture extract; preparing exosomes by using pomegranate pulp; and mixing the fermented velvet flower callus culture extract and exosomes isolated from pomegranate pulp in a certain ratio to prepare a mixture.
In the step of separating the exosomes from the above-mentioned pomegranate pulp, after pulverizing the portion of the pomegranate pulp, distilled water is used as a solvent, and heat-treated at a temperature of 60 to 70 ℃ for 2 to 3 hours, thereby performing hot water extraction, and then cooling and filtering to obtain exosomes. Specifically, the above-mentioned pomegranate pulp-derived exosomes can be obtained by the following steps: step (a), adding distilled water into the pomegranate pulp raw material and crushing; step (b), centrifugally separating the crushed material, and filtering supernatant to separate and remove dead cells and foreign matters; step (c) of subjecting the filtered supernatant to ultra-high speed centrifugation to form a primary particle layer comprising exosomes; a step (d) of subjecting the supernatant, which has been subjected to the centrifugation in the step (c), to centrifugation again to form a secondary particle layer containing exosomes; and (e) separating exosomes from the pomegranate pulp by re-suspending the primary and secondary particle layers in purified water. More specifically, the above-mentioned pomegranate pulp-derived exosomes can be obtained by the following steps: step (a), adding distilled water with the weight ratio of 20 times to the pomegranate pulp raw material, crushing, and stabilizing the crushed material for 24 hours at the temperature of 4 ℃; step (b), after centrifugally separating the crushed material by using a centrifugal separator, taking only supernatant fluid of the crushed liquid to separate and remove dead cells and foreign matters; step (c) of filtering the supernatant to remove residues; step (d), centrifugally separating the supernatant by using a super-high speed centrifugal separator, and precipitating exosomes to form a primary particle layer; step (e), after the supernatant is subjected to centrifugal separation again by using a super-high speed centrifugal separator, precipitating additional exosomes to form a secondary particle layer; step (f), repeating the steps (d) and (e) 2 to 3 times to isolate high purity exosomes; and (g) separating exosomes from the pomegranate pulp by re-suspending the particle layer formed in the above step in purified water.
The mixture of the velvet flower callus culture extract and the pomegranate-derived exosomes prepared by the above method may be formulated into various forms of cosmetic compositions by conventional methods.
The cosmetic composition may be in the form of a lotion, astringent, nourishing lotion, nourishing cream, massage cream, eye essence, cleansing cream, facial mask, powder, body cream, body essence, body wash, hair dye, shampoo, conditioner, hair setting agent, hair tonic, ointment, gel, cream, patch, spray, powder, skin adhesive type, etc., but is not limited thereto.
In addition, for each dosage form, in addition to the above-described essential components, one of ordinary skill can appropriately select and combine other components according to the kind of other dosage forms, the purpose of use, and the like.
The above cosmetic composition can be provided in all dosage forms suitable for topical application. For example, it can be provided in the form of a solution, oil-in-water emulsion, water-in-oil emulsion, suspension, solid, gel, powder, paste, microneedle, foam, or aerosol composition. The composition of such dosage forms may be prepared according to methods conventional in the art.
The cosmetic composition of the present specification may further comprise functional additives other than the compounds of the present specification and ingredients contained in conventional cosmetic compositions.

Comparative example 2: preparation of Granati-derived exosomes-
In order to separate exosomes from the pomegranate pulp, purified water in an amount of 20 times by weight is added to the portion of the pomegranate pulp and soaked, and then crushed by a crusher. Thereafter, in order to increase the purity of exosomes, the pulverized pomegranate is centrifugally separated at 3000 to 4000xg for 10 minutes using a centrifugal separator, and only the supernatant is taken except for the pellet layer to separate and remove the residues. For the supernatant obtained in the present process, centrifugal separation was performed at 10000 to 15000xg for 20 to 30 minutes using an ultra high speed centrifugal separator (ultra high speed centrifugal), and in order to further improve the purity of the obtained supernatant, further improvement of the purity was attempted by filtering the supernatant and separating and removing the residue. The exosomes present in the high-purity supernatant were centrifuged at 100000 to 150000xg by means of an ultra-high-speed centrifugal separator for 2 to 4 hours, and then the exosomes were precipitated in the pellet layer. Exosomes were prepared by suspending exosomes as the final particle layer in sterile distilled water again, dispersing them.

Experimental example 5 evaluation of NO production inhibitory Capacity
In a 96-well plate (well plate) at 5X 10 4 Cell/well amounts after inoculation with RAW264.7, culture was performed under cell culture conditions. After 24 hours, the culture medium was removed and washed with PBS, and the cells were starved using DMEM medium without FBS. The next day, a concentration of test substance was treated with 5. Mu.g/ml lipopolysaccharide (Lipop olysaccaride, LPS) and incubated. After 24 hours, the same amount of cell culture solution and griess reagent (griess reagent) were added and mixed, and then reacted at room temperature for 15 minutes. Absorbance was measured at 560nm, and the amount of Nitrogen Oxides (NO) as an inflammatory mediator was determined using a standard curve obtained from Sodium nitrite (Sodium nit rite). The amount of final NO was converted to the amount of NO in each certain protein and compared with a negative control group, and is shown in fig. 9.
From the experimental results, it was confirmed that NO inhibitory activity was excellent in the case of the mixed-fermented chenopodium falciferum callus culture extract and the pomegranate-derived exosomes. In particular, the NO production-inhibiting activity was most excellent when the mixing ratio of the fermented velvet flower callus culture extract and the pomegranate-derived exosomes was 7:3 (example 2). Therefore, the effect of inhibiting NO generation was more excellent when the fermented velvet flower callus culture extract and the pomegranate-derived exosomes were used in combination than when the fermented velvet flower callus culture extract and the pomegranate-derived exosomes were used alone, and the effects due to the optimum mixing ratio were confirmed, and are shown in table 9.

Experimental example 6 evaluation of TNF-alpha production inhibitory Activity ]
In Dulbecco 'modified Eagle' medium (DMEM) supplemented with 10% (v/v) fetal bovine serum, streptomycin and penicillin at about 37℃with 5% CO 2 Macrophage RAW264.7 was cultured and 1×10 5 Cell/well amounts were seeded in 96-well plates.
Next, the compositions prepared according to examples 1 to 4 and comparative examples 1 and 2 were treated in accordance with the concentrations, stimulated with LPS (5. Mu.g/mL) and cultured for 24 hours, and then cell culture broth was recovered and the amount of TNF-. Alpha.was measured using an enzyme-linked immunosorbent assay kit (ELISA kit) (R & D System Inc. Minneapolis, minnesota). The amount of TNF- α was quantified using the TNF- α standard curve for each concentration contained in the Kit (Kit).
In addition, indomethacin (20. Mu.g/mL) was used as a positive control group by treatment instead of the sample, and was used in comparison with the TNF-. Alpha.inhibitory activity of the sample.
From the experimental results, it was confirmed that the LPS-treated group induced production of TNF-. Alpha. 929.3pg/mL, which was increased by about 4.1-fold in statistical significance when compared to the negative control group (226.3 pg/mL). In examples 2 to 4, production of TNF-. Alpha.was demonstrated in 579.0pg/mL, 644.38pg/mL and 811.23pg/mL, and in particular, it was confirmed that example 2 showed an inhibitory activity having a statistically significant meaning of about 37.7% as compared with the LPS control group. Furthermore, the mixed fermented raw material of the velvet flower callus culture extract and the pomegranate-derived exosomes appears to increase TNF- α inhibitory activity in a concentration-dependent manner. It was finally confirmed that example 2 has the most excellent TNF-. Alpha.inhibitory activity among examples 2 to 4.
Therefore, it was confirmed that the effect of suppressing TNF- α production was more excellent when the fermented velvet flower callus culture extract and the pomegranate-derived exosomes were used in combination than when the fermented velvet flower callus culture extract (comparative example 1) and the pomegranate-derived exosomes were used alone (comparative example 2), and the mixing ratio was very important, and this is shown in table 10.
