If such conditions are deepened, the antioxidant defense network existing in the living body may be destroyed, Thereby promoting adult diseases and aging.

Therefore, it is necessary to protect the cell membrane by destroying the free radicals mediated by free radicals, ultraviolet rays, and inflammation that occur during the metabolism of the body and to proliferate cells by regenerating already damaged cells by active metabolism The skin can be maintained.

On the other hand, melanin is oxidized by tyrosinase to tyrosine (DOPA, 3,4-dihydro xyphenylalanine), converted to dopaquinone by redox oxidation, and then converted to non-enzymatic oxidation Reaction. Melanin protects the skin organs below the dermis by blocking ultraviolet rays, and at the same time, it plays a useful role in protecting the damage of proteins and genes in skin caused by free radicals generated in the skin of the skin. However, when melanin is produced more than necessary, It causes aging and causes hyperpigmentation such as spots or freckles. Melanin has the ability to remove reactive oxygen species, but sometimes melanin itself generates free radicals. It also reduces or oxidizes other substances by catechol or quinone in the melanin structure, and melanin itself has the property of free radicals do. Therefore, inhibition of melanin production may result in a skin whitening effect.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood by those skilled in the art that these embodiments are merely illustrative of the present invention and that the scope of the present invention is not construed as being limited by these embodiments.

Example 1. Preparation of Artemisia cinerea extract

Artemisia Capillaris ; AC; After 1 ~ 2 times of washing with distilled water and drying for 1 ~ 2 days at 20 ~ 60 ℃, 1,500 ml of alcohol, methanol or distilled water was added to 1,000 g of dried eggplant. And extracted at room temperature for 12 to 36 hours. Thereafter, the mixture was naturally filtered using a filter paper having a pore size of 5 쨉 m or less. The filtrate was concentrated by using a vacuum concentrator to a Brix of about 3 to 6 as measured by a sugar content meter, lyophilized, And homogenized to obtain 96.7 g of Artemisia sp.

Example 2. Preparation of fractionated organic solvent

2000 ml of ethyl acetate mixed solution (1000 ml of ethyl acetate, 1000 ml of water) was added to 96.7 g of the extract of Artemisia japonica extract (ethanol extract) of the present invention prepared through the alcohol (ethanol) in Example 1 at room temperature for 12 to 36 hours The ethyl acetate fraction and the water fraction were separated and filtered to prepare the ethyl acetate fraction and water fraction of the present invention, respectively.

The obtained ethyl acetate fraction (52.2 g) was further suspended in 1,400 ml of 90% methanol mixed solution (700 ml of 90% methanol, 700 ml of hexane) and extracted at room temperature for 12 to 36 hours. The residue was divided into a 90% methanol layer and a hexane layer The fractions were respectively separated / filtered to produce the methanol fraction and hexane fraction of the present invention.

Example 3. Preparation of fractionated fractions (Fr. 1 to Fr. 7) of organic solvent fraction

In order to obtain a sub-fraction exhibiting activity among the methanol fractions prepared in Example 2, 5 g of a 90% methanol fraction was used as a solvent, and a YMC-DispoPack AT SIL-25 column was used as a solvent containing ethyl acetate and hexane as a solvent. MPLC (LC-Forte / R, YMC) was performed. Starting with a solvent (20% ethyl acetate solution) with a ratio of ethyl acetate and hexane of 20:80 and gradually increasing the amount of ethyl acetate in the solvent until the concentration of ethyl acetate reaches 100% The solvent was flowed at a flow rate of 30 ml / min for 60 minutes. At this time, three wavelengths of 254 nm, 285 nm, and 356 nm were detected as the UV wavelength, and each fraction was fractionated based on the eluted peak to obtain a total of 7 fractions. This is named Fr.1 to Fr.7, and the time and solvent concentration of each fraction are shown in the table below.

Figure 112015059201423-pat00002

The fractions isolated in each step were concentrated with a vacuum concentrator, lyophilized and homogenized with a mixer in the absence of moisture. The process of obtaining the extract of the present invention and its fractions is shown in FIG.

Experimental Example 1. Measurement of Anti-inflammatory Activity of Artemisia capillaris Extract

Induction of nitric oxide by induction of inflammatory reaction was measured by greiss reagent after stabilization of nitrite to nitrate. The inhibitory activity of nitric oxide (NO), an indicator of cellular inflammation, was determined by measuring the amount of nitrate produced during LPS - induced inflammation. Specifically, RAW264.7 cells were cultured in 96-well plates at a cell density of 5 X 10 4 cells / ml in DMEM containing 10% (v / v) FBS, 100 units / ml penicillin and 100 ug / ml streptomycin seeded by ㎕ were incubated for 6 hours in an incubator of 37 ℃, 5% CO 2 condition. After that, 150 μl of the cell culture supernatant was centrifuged, and then 100 μl of the supernatant and 100 μl of the Griess reagent were reacted for 5 minutes, and an ELISA reader And the absorbance at 540 nm was measured. At this time, the NO inhibitory activity of each treatment was determined by comparing the relative amounts of NO produced as a final product based on the standard NaNO 2 , and the activity was determined as an index of anti-inflammatory activity. The amount of NO produced in the group to which LPS alone was added was regarded as 100%, and the addition of the sample was evaluated in terms of%.

As a result, LPS was a control group that induced inflammation reaction. Normal cells were not treated with LPS, and thus, NO inhibitory effect was not obtained. In addition, (See FIG. 2). From these results, it was found that the extract of Artemisia princeps of the present invention exhibits anti-inflammatory activity.

Experimental Example 2. Antioxidant activity measurement of Artemisia sp.

The antioxidative activity of free radical scavenging ability was measured by confirming the ability of reducing or canceling the free radical DPPH, that is, the oxidation inhibiting activity. DPPH was used as a measure of antioxidant activity because it was decolored and reduced by a sample with a relatively stable free radical having a deep purple color. L-ascorbic acid was used as a positive control and DPPH (1,1-diphenyl-2-picryl hydrazyl) method was used for comparison. 200 μl of 0.2 mM DPPH ethanol solution was successively diluted 2-fold with the extract of Artemisia japonica extract, reacted at room temperature for 30 minutes, and the absorbance at 517 nm was measured. The free radical scavenging activity was determined using the following equation, and the electron donating ability was expressed by the absorbance reduction rate of the sample solution addition group and no addition group.

Free radical scavenging ability (%) = (1 - absorbance of sample addition group / absorbance of no addition group) X 100

As a result, DPPH radical scavenging activity was increased in a concentration dependent manner when the extract was treated by concentration, and about 84% of radical scavenging activity was observed at 100 ㎍ / ml treatment concentration. (See Fig. 3). Thus, it was found that the extract of Artemisia princeps of the present invention exhibits antioxidant activity.

Experimental Example 3. Measurement of whitening activity of Artemisia princeps

(1) preparation of cells

In the experiment for measuring whitening activity according to the present invention, melanoma-producing mouse-derived melanoma cells (B16F10 mouse melanoma cell) were used. The culture medium was 10% (v / v) FBS, 100 units / ml penicillin and 100 α-MEM containing streptomycin was used. The culture conditions were 5% CO 2 and 37 ° C.

(2) Cytotoxicity measurement

B16F10 cells were cultured in 96-well microplates at a concentration of 1 × 10 3 cells / well. After the cells were cultured for 48 hours, the supernatant was removed. MTT solution (100 μl) was treated at 36 ° C for 4 hours according to the measurement method of MTT (3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide) and then the culture solution was removed and 50 μl of DMSO was treated And the absorbance was measured with an absorbance meter (ELISA) at 540 nm. The measured values were calculated by the following formula.

Cytotoxicity (%) = (1-absorbance of sample addition group / absorbance of no addition group) X 100

As a result of comparing the survival rate of cells treated with B16F10 cells at various concentrations, the survival rate of B16F10 cells was not decreased, and thus it was confirmed that the B16F10 cells were not toxic to Melanoma cells (see FIG. 4).

(3) Measurement of intracellular melanin concentration

B16F10 cells were cultured in 6-well microplates at a concentration of 2 × 10 4 cells / well, and the samples were cultured for 48 hours, and the supernatant was removed. Cells were collected in tubes and melanin was eluted from the cells with NaOH and absorbance was measured at 405 nm.

When B16F10 cells were treated with the extract of Artemia japonica extract at different concentrations, melanocyte production was induced by stimulation of melanoma cells with α-MSH (Melanocyte Stimulating Hormone) Melanin production was inhibited. When the extract was administered at a concentration of 12.5 / / ml or more, the effect of inhibiting melanogenesis was excellent and the effect was excellent at a concentration of 12.5-100 / / ml, preferably 50-100 / / ml. In particular, when the concentration of Artemisia sp. Extract was 50 μg / ml, melanogenesis was suppressed to a degree similar to that of the control without α-MSH treatment (see FIG. 5). In addition, when melanin was extracted from cells and expressed as a concentration value, it was confirmed that melanogenesis was inhibited in a concentration-dependent manner (see FIG. 6).

(4) Measurement of intracellular tyrosinase activity

B16F10 cells were cultured in 6-well microplates at a concentration of 2 × 10 4 cells / well, and the samples were cultured for 48 hours, and the supernatant was removed. The cells dissolved in the buffer were reacted with L-DOPA (L-3,4, -dihydroxyphenylalanine) and absorbance was measured at 475 nm.

As a result of measuring the degree of inhibition of the enzymatic activity of the extract of Artemisia cinerea against the enzyme tyrosinase (tyrosinase), which is the most related to melanin formation in melanoma cells, melanoma cells were stimulated with α-MSH to induce melanogenesis , Tyrosinase activity was also increased (about 157% of tyrosinase activity was found in α-MSH treatment), and tyrosinase activity was inhibited in a concentration-dependent manner upon treatment with Artemisia sp. Extract (tyrosinase activity at a concentration of 50 μg / and about 107% when melanin without α-MSH was taken as 100%) (see FIG. 7). When the extract was administered at a concentration of 12.5 / / ml or more, the effect of inhibiting tyrosinase activity was excellent and the effect was excellent at a concentration of 12.5-100 / / ml, preferably 50-100 / / ml.

(5) Summary of results

As shown in Experimental Examples 1 to 3 of the present invention, the extract of Artemisia princeps of the present invention showed anti-inflammation, antioxidant or skin whitening activity, and the composition containing it as an active ingredient contained 12.5 to 100 ㎍ / ml, preferably 25 to 100 占 퐂 / ml, more preferably 50 to 100 占 퐂 / ml, exhibits excellent anti-inflammatory, antioxidative and whitening activity. It was confirmed that the same or similar effect was obtained at a concentration of 100 / / ml or more in the case of treatment with 100 / / ml, and the above-mentioned preferable concentration was in accordance with the concentration used in cell treatment in vitro , The present invention is not limited thereto.

Experimental Example 4. Measurement of whitening activity of organic solvent fraction

In order to confirm whether each of the organic solvent fraction (ethyl acetate fraction, water fraction, methanol fraction, and hexane fraction) of the present invention produced in Example 2 exhibited similar activity to the extract of Artemisia princeps, The intracellular melanin concentration was measured to confirm the whitening activity.

Specifically, the mouse-derived melanoma cells (B16F10 mouse melanoma cell) producing melanin were used for the measurement of whitening activity, and the culture medium was prepared by adding 10% (v / v) FBS, 100 units / ml penicillin and 100 unit / Α-MEM containing mitomycin was used. The culture conditions were 5% CO 2 and 37 ° C. For measurement of intracellular melanin concentration, B16F10 cells were cultured in a 6-well microplate at a concentration of 2 × 10 4 cells / well, and each sample (extract or fraction) was added to each concentration and cultured for 48 hours to remove the supernatant . Cells were collected in tubes and melanin was eluted from the cells with NaOH and absorbance was measured at 405 nm.

(1) Ethanol extract, (2) Ethyl acetate fraction, (4) Ethanol extract, (2) Ethyl acetate fraction, (3) Water fraction, ) Methanol fraction inhibited melanogenesis of cells in a concentration-dependent manner. In contrast, (3) water fraction and (5) hexane fraction did not inhibit the melanin production inhibitory activity (see FIGS. 8 and 9) .

The IC 50 value refers to the inhibitory concentration 50 (fifty), the inhibition concentration or the inhibition concentration. When the size of any reaction A is assumed to be 100%, the size of reaction A is reduced to 50% If possible, the concentration of B at that time is called the IC 50 of B for reaction A. If the IC 50 value is 1.4 μg / ml, it means that only 1.4 μg / ml is required to inhibit any reaction to 50%. As a result, the smaller the IC 50 value, the stronger the ability to inhibit the reaction. The IC 50 values of (1) ethanol extract, (2) ethyl acetate fraction and (4) methanol fraction showing whitening activity were compared and the results are shown in the table below.

Figure 112015059201423-pat00003

As can be seen from the above results, the extract was prepared by extracting Artemisia japonica with ethanol and then sequentially extracted with a mixed solution of ethyl acetate and water and a mixed solution of 90% methanol and hexane. As a result, the ethyl acetate extract had the same weight 2.15 times, and the methanol fraction exhibited a high whitening activity (ability to inhibit melanin formation) of 3.74 times as much as the same weight.

As a result of TLC (Thin Layer Chromatography), it was confirmed that a substance expected to be an active ingredient exists only in a fraction exhibiting whitening activity upon irradiation with UV at a wavelength of 365 nm (see FIG. 10 (c)).

In conclusion, the ethyl acetate fraction and the methanol fraction thereof of the present invention show much higher whitening activity than the Artemisia sp. Extract, which can be expected because the active ingredient is concentrated.

Experimental Example 5. Measurement of whitening activity of fractionated fractions of Artemisia sp.

In order to confirm whether each of the fractions (Fr. 1 to Fr. 7) of the fragrant organic solvent fraction of the present invention produced in Example 3 exhibited similar activity to the extract of Artemisia princeps or its organic solvent fraction, The intracellular melanin concentration was measured in the same manner as in the method described in (3) to confirm whitening activity.

As a result, it was confirmed that whitening activity (inhibitory activity on melanin formation) was observed in Fr 1 to Fr 5 subfractions, which was obtained by treating a 90% methanol fraction with a 20% to 66.6% ethyl acetate solution, Which means that the activity is much better.

In conclusion, the extract of Artemisia japonica extract or its organic solvent fraction of the present invention exhibits excellent whitening activity. Particularly, the fractions obtained by sequentially treating the ethanol extract of Artemisia wisdomini with ethyl acetate and 90% methanol are mixed with 20% to 67% of ethyl It was found that the supernatant fractions obtained by further separation using acetate as a solvent showed the best activity. In particular, it was confirmed that the activity of inhibiting melanin formation was very high in Fr.1 to Fr3 and Fr.5 in which the concentration of ethyl acetate was 20 to 50% or 55 to 66%.

In addition, when compared with 500 ug arbutin used as a positive control, it was confirmed that melanin was hardly produced even when the fraction of the present invention was treated with 30 ug of 17-fold lower concentration. Thus, the fraction according to the present invention has a low concentration And thus it can be used effectively as an active ingredient of various compositions such as cosmetics, soaps, medicines or foods.

Having described specific portions of the present invention in detail, it will be apparent to those skilled in the art that this specific description is only a preferred embodiment and that the scope of the present invention is not limited thereby. It will be obvious. Accordingly, the actual scope of the present invention will be defined by the appended claims and their equivalents.
