Benefits of technology

[0021]3,5-di-o-methyl-gartanin derived from a white rose petal extract or white rose petal has a whitening effect by suppressing melanin production through a mechanism of inhibiting tyrosinase activity and has effects of enhancing skin elasticity and alleviating a wrinkle through a mec

Problems solved by technology

Various causes of the wrinkle generation have been reported and first, when the skin is exposed to excessive UV, decomposition of collagen as a skin ingredient is accelerated and thus the skin elasticity is lost and the wrinkle may be generated.
Further, when the skin is excessively dried by an excessive change in temperature, a decrease in humidity, wind, or the like, the skin function as a barrier to the outside is deteriorated and the wrinkle is generated.
As a result, the wrinkle is generated due to functional and structural damages and thus the skin aging is accelerated.
Particularly, in recent years, whitening cosmetics using the placenta extracts have been in the limelight, but in the placenta extracts, the supply amount is limited and the use there is limited in a combination of ethical issues.
However, in these whitening ingred

example 1

Preparation of White Rose Petal

[0063]The white rose petal used in the present invention was collected at Jincheon, Chungbuk, Korea in May, 2010 and then completely dried under the sun and used. The completely dried petal was grinded and powdered by using a rotor speed mill (Laval Lab Inc., Laval, Que), sterilized by using a 70% ethanol spray, dried at 80° C., and then stored at 4° C. before usage.

Preparation of White Rose Petal Extract

[0064]The prepared dried white rose petal powder was divided into two parts and extracted with ethanol or water.

[0065]First, the ethanol extract was deposited by using 70% ethanol 10 times larger than a volume of the white rose petal powder and extracted for 24 hours at room temperature. An extracted suspension was filtered by a Whattman filter (No. 1) and the filtrate was concentrated under a vacuum at 50° C. and freeze-dried to obtain the extract. Samples obtained from the ethanol extract were continuously fractioned through n-hexane ethyl acetat (EA), chloroform, n-butanol (BuOH), and distilled water, and the obtained fractions were dried by an evaporator. Then, the obtained products were used for the experiments.

example 3

Analysis of Collagen Matrix Metalloproteinase-1 Inhibitory Effect of White Rose Petal Extract

[0066]As part of measuring a wrinkle alleviation effect of the white rose petal extract, effects of inhibiting activity of collagen matrix metalloproteinase-1 (MMP-1) of the extracts were measured with reference to the guideline of “beauty-related functional tests (pp. 821-858)” of Korea health official compendium research society foundation.

[0067]When simply describing the effect, 25 mg of bovine tendon collagen was dissolved in a 0.05 M tris(hydroxymethyl)-methyl-2-aminoethane sulfonate (TES) buffer and then left for 15 minutes at 37° C. Next, a test material for each concentration was added and then additionally reacted with collagenase type-1 for 5 hours at 37° C. 0.2 mL of a reaction solution was taken and added to 1 mL of a buffer [14% ninhydrin in methyl cellosolve (2-methoxyethanol)+0.2 M sodium citrate with 0.71 mM stannous chloride]. The reaction solution was boiled for 20 minutes,...

Abstract

Provided is a functional cosmetic composition of white rose extract and a gartanin derivative compound isolated therefrom, and specifically, to a cosmetic composition for skin whitening and skin wrinkle alleviation containing, as active ingredients, white rose petal extract and gartanin derivative compounds isolated therefrom. The white rose extract and gartanin derivative compound, according to the present invention, are safe without causing side effects on the skin, prevent melanin production through a mechanism inhibiting tyrosinase activity, thereby having a whitening effect, and exhibit a wrinkle alleviation effect by a mechanism inhibiting MMP-1 activity, and thus the composition, of the present invention, containing the same as active ingredients, can be utilized as a material for functional cosmetics for skin whitening and wrinkle alleviation without causing skin irritation.

Description

TECHNICAL FIELD[0001]The present invention relates to a functional cosmetic composition including, as an active ingredient, white rose extract, and more particularly, to a functional cosmetic composition having skin whitening and wrinkle alleviation functions including, as an active ingredient, white rose extract.BACKGROUND ART[0002]The skin is a defense organ on the front line of the human body which protects the body from external stimuli and even from the aesthetic point of view, an interest thereof has been gradually increased. Accordingly, studies on a variety of functional cosmetics are actively conducted and among the studies, various functional cosmetics for wrinkle alleviation and whitening functions are being launched.[0003]Skin aging is largely divided into two types of intrinsic aging and extrinsic aging according to a cause thereof. The intrinsic aging is an aging process which is naturally caused while a physiological function of the living body is deteriorated as the ...
