[Invention Title]
A COSMETIC COMPOSITION COMPRISING TISSUE CULTURED PANAX GINSENG C.
A. MEYER ADVENTITIOUS ROOT ITSELF AND A PREPARING METHOD THEREOF
[Technical Field]
The present invention relates to a cosmetic composition comprising
tissue-cultured adventitious roots itself of a ginseng, and to a preparing
method thereof. This application claims priority from Korean Patent
Application No. 10-2007-0005237 filed on January 17, 2007 in the Korean
Intellectual Property Office, the disclosure of which is incorporated
herein by reference in its entirety.
[Background Art]
Generally, functional cosmetics comprising a plant extract is
prepared through multiple steps such as seeding, culturing, harvesting,
washing, drying, dipping, aging, and filtering for a cosmetic composition.
Therefore, there is a drawback that the process for preparing the cosmetics
requires long time and high cost.
It is possible that a large amount of ingredients having a high
purity can be obtained in short time in the case of an extraction or
supercritical extraction method using a solvent . However, the ingredients
extracted by the extraction method have problems in their stability such
that they can be precipitated due to light, air, temperature or the like,
or their colors can be changed with the passage of time. Accordingly, upon
adding the ingredients to a cosmetic composition, there is caused a problem
that they may affect the properties of the cosmetic composition.
Since the extracts are typically obtained through dipping or aging
for a short time without aging for a sufficient period, they have a problem
that a sufficient effect of extraction of effective ingredients is hardly
expected. Further, since the effective ingredients cannot be extracted
in a large amount without further isolation and/or purification step,
cosmetics comprising a high concentration of the effective ingredients
is hardly prepared with the extract itself.
A consumer to purchase functional cosmetics cannot recognize
visually the presence and contents of an extract containing the effective
ingredients, and cannot but purchase and use depending on only labeled
ingredients on the package of a cosmetic.
In order to improve the above-described problems, a preparing
method for cosmetics comprising a plant itself, not a plant extract, was
proposed. However, the method has a drawback that cost is required for
sterilizing the plant and a product having uniform quality cannot be
achieved due to its different size, harvesting places and periods of the
plant added to composition.
A cosmetic composition comprising an undifferentiated callus using
a recent tissue culture technique was disclosed in Korean Patent No.637342.
A callus means a cell mass of which function is not determined. Accordingly,
a callus has been known to have different types and contents of effective
ingredients from those of the differentiated plants.
A korean wild ginseng ("Sansam"), which is an example of a plant
containing a large amount of a functional ingredient, belongs to Panax
ginsengC. A. Meyer (hereinafter "ginseng") of the Araliacea family, and
grows natural Iy in a mountain. A korean wi Id ginseng belongs to a flowering
plant and angiosperms, in which a peduncle grows with leafs and a stalk
upon budding, and to a semi-shade plant.
A korean wild ginseng has been recorded as a "mysterious herb" in
Dongeui Bogam (the integration of traditional Korean medicine).
Traditionally, it has been thought to be a celebrated medicinal herb as
a rare herb, and as a result, it has been used as a therapeutic agent for
various diseases and a nutrient supplement.
The main component of a ginseng is a glycoside. The mixture of
glycosides is hydrolyzed with an acid to give a free sugar such as glucose,
rhamnose, sucrose and fructose, and aglycone, and to give panaxadiol and
panaxatriol, β-sistosterol and oleanolic acid as a saponin glycoside.
Panacene, which is a sesquiterpenoid compound, is an aromatic component.
Further, it has been known that other components, such as β-sistosterol,
stigumasterol ; alkaloid; flavonoids such as kaempherol, trifolime, and
panasenoid; vitamins such as B complex, nicotinic acid, pantothenic acid,
folic acid and biotin; trace elements such as manganese, copper, vanadium,
cobalt, arsenic, germanium, phosphorus, aluminum and nickel ; germanium
cell enzyme; and enzymes such as amylase, and phenolase, are contained.
According to the results from clinical research, it has been found
that a ginseng has an efficacy such as antidiabetic effect, anticancer
effect, cardio-stimulation, regulation of blood pressure, stimulation of
liver function, stimulation of stomach, stress relief and restorative
activity, stamina enhancement , stimulation of brain function, anti-aging
activity, radiation protection, effect on anemia and hematopoiesis,
immunity enhancement, ant i-inflammatory effect and asthenia improving
effect. The efficacy of the korean wild ginseng is similar to that of a
cultivated ginseng, but the korean wild ginseng is more excellent with
respect to the pharmacological effect.
Generally, a korean wild ginseng is divided into four categories
in Korea, i.e. ("Cheonjong, Jijong, Injong, Jangnoi"). Specifically,
Cheonjong (natural wildginseng) naturally occurs from wild seeds; Jijong
is propagated, for which animals or birds eat and excrete their seeds;
Injong is cultured by human! and Jangnoi (wild simulated ginseng) is
obtained by collecting the seed, seeding in the mountain, and artificially
growing it in a wild state. A seed of the wild ginseng does not easily
germinate, and even if the seed sprouts or germinates, it can survive just
few years . Therefore, the wi Id ginseng is a rare plant which it is difficult
to culture.
Recently, to solve the drawbacks such as a rareness of the wild
ginseng and high value-added of the products, a method for
mass-propagating the adventitious roots using the root tissue of a wild
ginseng and the technique of the plant tissue culture had been known.
Accordingly, the adventitious roots of a wild ginseng having uniform and
excellent quality can be cultured in a large amount and a short period
comparatively, which will be used for various foods or as a raw material.
For example, in the case of preparing an alcoholic beverage, a cultivated
ginseng, a Japanese apricot , gold was added and aged to improve its flavor,
and a cultivated ginseng itself was contained in a beverage to enhance
trust for the product with visual effect. However, a cosmetic composition
comprising adventitious roots itself of a wild ginseng has not been
published or disclosed yet.
Therefore, the inventors of the present invention have made
extensive studies on preparation of a cosmetic composition, which stably
comprises effective ingredients of a ginseng. They have found that the
ingredient dip-extracted from the adventitious roots of a ginseng was
uniformly maintained by adding a tissue-cultured adventitious roots
itself of a ginseng to a cosmetic composition, and that user satisfaction
was high in a sensory test, thereby completing the present invention.

1-2. Test for effect of promoting collagen biosynthesis
To confirm the anti-wrinkle effect of the cosmetic composition
according to the present invention, the effect of promoting collagen
biosynthesis was measured using fibroblasts. Mouse fibroblast (3T3-L1,
KCLB 10092.1, Korean Cell Line Bank) were cultured using DMEM medium
(Dulbecco's Modified Eagle's Medium, Invitrogen, USA) containing 10 %
(v/v) FBS (fetal bovine serum, BioWhittaker, MD, USA) and 1% (v/v)
penicillin-streptomycin (BioWhittaker, MD, USA) under the condition of
5% CO2 and 37°C . After eel 1 culture, the eel Is were col lected with treat ing
trypsin. The collected cells were seeded in a 24-well plate at a
concentration of IxIO 5 cells/in-C/well , followed by culturing for 24 hours.
After cell culture, each cosmetic compositions prepared according to the
formulations in Example 3 and 4, and Comparative Examples 3 and 4 were
diluted to 0.01%. The cells were treated with the diluted cosmetic
compositions and cultured for 24 hours, followed by using for the following
experiment .
In order to confirm whether collagen biosynthesis was enhanced in
the fibroblast or not, the supernatant of the cultured cells was collected
to determine the amount of collagen.
Specifically, 1 mi of a dye reagent (prepared by dissolving 0.1 g
of a sirius red reagent (BDH, UK) in 100 ml of saturated picric acid) was
added to 100 μi of the supernatant. The mixture was subjected to reaction
under slow stirring at room temperature for 30 minutes. Sirius red is an
anionic pigment, which specifically binds to collagen. After 30 minutes
reaction, a collagen-pigment complex was precipitated by a centrifuge at
over 5000Xg for 20 minutes.0.5 M of NaOH was added to the precipitate
to dissolve at room temperature for 5 minutes. Absorbance of the solution
was measured using a micro well plate reader at 540 nm. The result was
shown in Tables 9 and 10. The results were compared with the absorbance
values of the non-test group to evaluate the effect of promoting collagen
biosynthesis.

hydrochloric acid was added thereto to adjust the pH to 2.0. The solution
was placed in a separatory funnel . The equal amount of chloroform was added
thereto. The solution was vigorously shaken and left to separate an aqueous
layer. After the operation was repeated twice times, the obtained aqueous
layer was concentrated under reduced pressure at 60 ° C . 1 N of sodium
hydroxide was added thereto to adjust the pH to 6.5. Further, purified
water was added thereto to be a volume of 20 ml,. The solution was filtered
and a phosphate buffer (pH 6.5) was added to 5 ml of filtrate to be a volume
of 10 ml as a test solution.10 μl of the tyrosinase enzyme solution was
added to 170 μl of the test solution, and left at 37°C for 10 minutes.
20 μl of the substrate solution was added thereto. The reaction was carried
out at 37°C for 10 minutes, and immediately left in ice for 5 minutes.
Absorbance was measured using an ELISA reader (UV max kinetic microplate
reader 01414, Molecular Devices, USA) at 490 nm. The absorbance measured
was substituted into Equation 1 to calculate the inhibition ratio of
tyrosinase activity. The result was shown in the following Table 11 and
12. A phosphate buffer (pH 6.5) instead of the test solution was added
to prepare a blank solution. Further, a phosphate buffer (pH 6.5) instead
of the substrate solution was added to prepare a calibration solution.
