[1]

The present invention refers to around [kays[kays] qualities (LimoniumTetragonum)Effective for skin whitening composition are disclosed.

[2]

The interior of the body from the environment of our various external skin protecting the most outside a body organ while the largest engine we are disclosed. The bottom of the keratinocytes (keratinocytes) number in these skin billion, or macrophage (macrophage) (Langerhans cells) skin immune is responsible for with gel one [su[su] cell, enter the dermal fibroblast (fibroblasts), and the like present oligonucleotide which is responsible for generating pigment (melanocytes).

[3]

Melanin is a biomacromolecule can be an oligonucleotide synthesized from exterior environments of UV black skin protects cells which serves to protein complex are disclosed. However human melanin generating an excess of melasma, ephelis or the like and can even cause skin cancer form (J. P. Ortonne and J. J. Nordlund, The pigmentary system: physiology and pathophysiology, eds. J. J. Norlund, R. E. Boissy, V. J. Hearing, R. A. King and J. P. Ortonne, 489, Oxford University Press, New York, 1998).

[4]

The melanin is present in proteins involved in number and it is sour with the mote but Ohit is sour with the mote but Oh oligonucleotide number generated by the action of (tyrosinase related protein). Specifically it is sour with the mote but Oh number (tyrosinase) by tyrosine (tyrosine) to be used as a waveguide (DOPA, 3, 4 a-dihydroxyphenylalanine), ear waveguide it is a jade city number as a function of the waveguide into a waveguide quinone (dopaquinone) (dopaoxidase) after being oxidized again, it is sour with the mote TRP-a 1 number related protein (5, 6 a-dihydroxy indole-a 2 non-carboxylic acid oxidase) and TRP provided 2 (dopachrome tautomerase) generated by the action of. Number it is sour with the mote, transcription factor MITF (microphthalmia non-associated transcription factor) TRP-a 1 and TRP-a 2 is expressed by is promoted, MITF is ERK (extracellular signal-a regulated kinase) is activated if a billion over known number expression (DS Kim, et al. , J Cell Sci. 2003;116: 1699 - 706).

[5]

Generating a first step number participates to it is sour with the mote but Oh since melanin for inhibiting a second operation end studies find number number number whitening it is sour with the mote but Oh immunohistochemical studies (Kor. J. Pharmacogn. , 44 (3): 220, 2013). The majority of the current number and number are employed primarily whitening number such it is sour with the mote but Oh inhibitor, hydroquinone (hydroquinone) (arbutin, beta-D non-glucopyranoside) in which it is glycoside is arbutin, kojic acid (kojic acid) having inhibitory activity on both it is sour with the mote but Oh number like whitening number are disclosed. Hydroquinone (hydroquinone) is arbutin glycoside in which it is tolerable number it is sour with the mote but Oh (arbutin, beta-D non-glucopyranoside) a substance inhibiting the activity and, kojic acid (kojic acid) number it is sour with the mote but Oh chelating activity to tyrosine in the waveguide, waveguide quinone progressed into a substance inhibiting the process are disclosed (Korean J. Plant Res. , 26 (5): 526, 2013; J. Korean Soc. Food Sci. Nutr. , 41 (2): 156, 2012).

[6]

However said whitening number number number is long-term in use both these synthetic whitening synthetic whitening is dermatitis, carbostyril derivatives for, back counter evidence, like the side effects of have, such as Taiwan some countries medical expert defined an acceptable concentration etc. available without prescription. Synthesis whitening human skin irritation and side effects to the safety door number number of these cookies to relatively small natural genuinely looking for extended studies in whitening material progressing disclosed.

2 Na-friendly salt lifestylearound [kays[kays] qualitieswith in [kays[kays] qualitative wondermentsyear lifestylethe seashoresalt lifestyle NaOCl in a rechargeable and high extraction process into plants belonging (Korean J. Ecol. , 13:9 - 18, 1990; Korean J. Ecol. , 6:167 - 176, 1983), forming a number of offshore the southwest gene in our area near room side guide seven cotton seconds, it does, old Mr. the herbs, etc. [kays[kays] grasses phones distribution (Korean J. Ecol. , 13:9 - 18, 1990; Korean J. Ecol. , 6:167 - 176, 1983). For example greater strength from the root [kays[kays] qualitative respects (Ocean Research 20:167 - 178; 1998) and NO3, health food or functional cosmetics to physiologically active ascertained [kays[kays] qualitative respects if a high safety is inserted into the can.

[8]

The present invention refers to melanin formation billion number based on skin whitening activity around [kays[kays] qualities extract number as the use of such disclosure as follows.

[9]

[1]

Disclosed is a skin whitening composition using an extract of Limonium tetragonum, which shows the melanin production inhibitory activity in a concentration-dependent manner when being treated on melanoma cell line B16F10 cells of mice stimulated by α-MSH, which is a melanin production inducer. The extract of Limonium tetragonum is obtained by using water, ethanol, or a mixed solvent thereof. The skin whitening composition of the present invention can be commercialized into foods, cosmetics, medicines, etc., and can have relatively less side effects compared to synthetic skin whitening agents since Limonium tetragonum roots have been used for edible purposes.
