Description
The present invention relates to a composition for external application for skin containing a camellia plant cell culture or an extract thereof and a method for producing the same, and more particularly, to an anti-aging external preparation for skin comprising a camellia plant cell culture or an extract thereof as an active ingredient, And a manufacturing method thereof.
Over time, the secretion of various hormones that regulate metabolism is reduced, and the function of immune cells and the activity of cells are lowered, so that the biosynthesis of immune proteins and biologic proteins necessary for the living body is reduced The skin becomes thinner (in the case of endogenous aging) and the elasticity is decreased by intrinsic aging which is caused by external aging and photoaging due to various pollutants and ultraviolet ray externally, Keratinocytes and melanocytes are damaged by UVB. Skin aging is divided into chronologic aging, which occurs in areas that are not exposed to sunlight, and actinic aging, which is a combination of chronologic aging and degenerative changes in the exposed parts of sunlight. In chronological aging, characteristic clinical signs of skin are fine wrinkles, atrophy of dermis, and decrease of subcutaneous fat layer. In the photoaging process, coatse wrinkling and furrowing appear and abnormal elasticity material accumulates and the skin thickens and loosens like leather. The phenomenon seen in chronic sunlight-damaged skin is an abnormal increase in the elastic elastosis and proteoglycan of the upper collagen of the dermis and a significant decrease in collagen, the main protein of the dermis. Collagen gives strength and tension to the skin, which protects the skin from external stimuli or forces, and it accounts for 90% of the dermis. Collagen reduction is closely related to skin and aging. In cells, cellular activity decreases due to endogenous senescence and photoaging, signal transduction system becomes incomplete, biosynthesis of matrix metalloproteinases (MMPs), which degrade skin tissue, is increased, collagen biosynthesis is reduced, and wrinkles are formed and elasticity , And it is known that melanogenesis leading to skin blackening is increased.
On the other hand, the skin barrier (Stratum corneum, skin barrier) consists of dead keratinocyte (intercellular lipid) and intercellular lipids, protects the skin from external stimuli and protects the skin from evaporating moisture It plays a key role in skin health. In other words, it prevents excessive release of water in the body and prevents harmful substances such as chemicals and microorganisms from entering our bodies. It plays an important role in intercellular lipid stability in keratinocyte envelope, which constitutes the surface of dead keratinocytes. The keratinocyte envelope is composed of protein membranes such as involucrin, loricrin, and filaggrin.
The keratinocytes make the skin barrier through the process of differentiation and currency keratinization. Skin barrier function can be aged or destroyed by external factors, and aged skin is easily destroyed by acetone or tape stripping. Damage to the skin barrier can cause skin moisture loss and wrinkles.
In addition, tight junctions consist of one type of cell junction, claudin, tricellulin, junctional adhesion molecule (JAM) and zona occluden (ZO). The tight junction can be divided into a part contained in the cell membrane and an intracellular part. Occludin and claudin are closely related constitutive proteins contained in cell membranes. Occludin is the first transmembrane protein found in adherent synapses and has four transmembrane domains. Occludin is known to regulate the function of tight junctions as well as constituents of tight junctions. Claudin, a close-coupled conformational protein with Occludin, also has four transmembrane domains. The tight junction is a cell-to-cell linkage that fills the gap between neighboring cells, controls the movement of small molecules, controls the permeation of cells between cells, and maintains the polarity of the cells. Recently, it has been reported that tight junctions play an important role in skin barrier function.

Hereinafter, the present invention will be described more specifically.
Camellia japonica Linne is an evergreen bark belonging to the tea and camellia. Camellia is distributed in about 100 species in Southeast Asia. One species is distributed in the southern part of Korea, and many kinds of horticultural varieties that make many changes such as flower shape, color and leaf are widely planted as ornamental plants. It grows up to 5 ~ 15 meters in height and grows in mountains of Jeju Island and southern part of Korea. The bark is grayish brown to yellowish brown, smooth, smooth and glossy, eggplant light brown with no hairs. Leaves are alternate, oval to long oval, thick leather, pointed end, wavy sawtooth on edge. The front side of the leaf is glossy and the back side is pale green. The petiole is about 5mm long.
The flowering period of camellia is from 12 to the following April, and the fruit is autumn. One red flower blooms on the tip of branch or leaf axil. There are many calyxes and fallen, and there is no peduncle. Five to seven petals spread diagonally and have many stamens. When petals fall on the petals, they fall together. Anther is yellow and style is divided into 3 pieces. Rounded seeds and berries are 2 to 3 cm long, ripen in red in autumn, and split into three halves, with dark brown seeds in them. The seeds are close to the elliptical shape and have a corner on the back (back) of about 2cm in length and 1.5cm in diameter. In the old days, oil made from seeds was called 'camellia oil' and was used as the head oil of the ladies.
It is called 'Camellia japonica Linne for albipetala H.Chang'. The Camellia sasanqua Thunberg, which originated from Japan, is distinguished from the Camellia japonica var. Hortensis Mak. By the fact that the leaf is smaller than the camellia and the underside of the petal is not attached, and the petal is spread almost horizontally.
Other names of camellia are camphor (camphor), camellia (camphor), camphor (camphor), camellia (camphor), camellia Tree, camellia, interpretation, and camellia oil.
The collection time of the camellia buds is sampled from the spring equinox to the bloom (April 20). Generally, when the bud is convex and the flower is about to bloom, collect it and dry it in the sun or put it in a weak fire, wrap it in paper, seal it, keep it in a dry and well ventilated place.
Camellia japonica contains leucoanthocyanin and anthocyanin. Fruit contains oil, camellin, thachysaponin, hydrolyzed thachysaponin, camelliagenin A, B, C, and leaves contain I-epicatechol and d-catechol.
Telomerase is composed of catalytic subunit telomerase reverse transcriptase (TERT) and telomerase RNA component (TERC) and plays an important role in telomere length regulation, aging and tumorigenesis. In addition, it participates in the regulation of DNA repair, chromatin remodeling, and metabolism through various cellular signaling. Indeed, many recent studies have demonstrated that the function of telomerase is regulated by interactions with various genes.
Most normal human somatic cells become shorter by telomic DNA every time cell division occurs due to the DNA end replication problem. Increasing shortening of telomere is an important mechanism to regulate cell senescence and cellular replication restriction. Telomerase plays an important role in maintaining telomere length, and nucloeytic degradation and end-to-end fusion occur to prevent cell death or recombination.
Above the role of telomerase in maintaining telomere length, several evidences about the physiological function of telomerase have been suggested. For example, when telomerase is expressed, cell survival increases even if cellular stress is induced, and it is known that TERT plays a role independently of telomerase activity in protecting cells from cell death. Therefore, TERT is involved in aging independently of telomere length control, which is a main function of TERT.
In other words, it is known that telomerase, which is a reverse transcription enzyme that maintains telomere length by inducing cell senescence in normal cells, is closely related to the promotion of differentiation and mitotic organization of cells.
In the present invention, in order to understand the possibility as an anti-aging material, it is confirmed that the cambrian plant cell culture or its extract is effective as an anti-aging material through the activity on the promoting activity of collagen production and the indicators related to the differentiation of keratinocytes In addition, we confirmed the action of promoting filaggrin production, which is an indicator of skin cell differentiation, that is, promoting the proliferation and differentiation of keratinocytes, thereby increasing the production of filamentous green cells.
In one aspect, the present invention relates to a method for producing a camellia plant cell culture characterized in that plant cells are isolated from a tissue of Camellia japonica plant and cultured.
In the present invention, a camellia plant is a concept including a camellia tree and a camellia flower. For example, the structure of a camellia plant may be a camellia or a seed of a tree, a camellia of a camellia, an ovary of a camellia, a camellia, Roots and so on.
In the present invention, the cultivation of the plant cells may be performed by separating and culturing the cells from the seeds, laver, ovary or petal of Camellia sinensis.
The placenta of the plant is an important part that regulates seed breeding, such as an animal-derived placenta. It is a part of the ovary in the pistil (ovary, ovary). It is usually on the edge of the carpel, which forms the ovary. It also occurs in the base of the ovary, or in the shape of a column standing upright in the ovary from the base.
In the present invention, the cultivation of the plant cells may be performed by separating and culturing the cells from seeds, leaves, stems, or roots of the camellia.
Plant tissue culture is a technique in which a living small plant tissue is aseptically cultured in vitro to grow plant cells, organs and plants according to the purpose of culture. Plant tissue culture can be attributed to the basic characteristics of plants. Plant tissue culture technology is based on the use of differentiating totipotency to regenerate plants from plant somatic cells, a unique feature of plants. Namely, plants can be regenerated from these cells and tissues by culturing single cells (including protoplasts), leaves and root sections of plants in a medium supplemented with specific nutrients and growth regulators. The ability of these plants to have differentiating totipotency is a strategy for survival from harsh environments and herbivorous damage for the fixation and long-term survival of plants. Therefore, plants can be said to have the ability to regenerate lost organs again. The plant tissue cells isolated from the parent plant have the potential to be reproduced as a complete plant when cultured in a suitable culture environment, that is, plants having typical performance are of academic importance such as embryology, but they are also utilized for practical use of cosmetic raw materials .
In the present invention, the plant cell may be cultured in a culture medium containing a plant growth regulator. In particular, the culture medium may be cultured in a culture medium containing NAA (alpha -naphthalene acetic acid) or 6-BAP (6-Benzylaminopurine) And then culturing the plant cells in a medium containing all of them.
In the present invention, the NAA (alpha -naphthalene acetic acid) may be contained at 1-10 mg / L, preferably 2-8 mg / L, 4-6 mg / L, and the 6-BAP may be 0.01-1 mg / L, preferably 0.05-0.5 mg / L, and 0.08-0.3 mg / L.

Such convergent action may be said to have an effect of forming an insoluble film on the surface of the skin and mucous membranes by external application or contents and consequently protecting the locality or densifying the tissue to reduce the permeability of the cell membrane.
The convergence of the skin is divided into two types: chemical convergence and physical forestation. Chemical convergence refers to temporary constriction of sweat glands and pores by substances that coagulate proteins like tannins. On the other hand, physical convergence refers to the temporary shrinkage of sweat glands and pores by using cold water on the skin or by lowering the temperature of the skin due to the volatilization of ethanol. In addition, such skin convergence is caused by summer stress or stress, skin trouble occurs when more sebum occurs, and the skin trouble becomes more and more reddened. Skin relaxation means relaxation of such skin troubles , And is an action distinct from skin convergence.

Experimental Example 6: Skin Convergence Effect Test of the composition for external application for skin according to the present invention
Astringency is defined as a binding reaction in Latin derived from as (to) and stringere (bind) in Latin. Convergence in the skin refers to the phenomenon that skin proteins contract with the polymer flavonoids to form a crosslink, causing the skin to contract. Commonly known as astringents are organic acid metal salts, inorganic metal salts and alcohols, and metal salts and inorganic metal salts are not suitable for cosmetic applications because they cause skin toxicity or skin diseases. Ethanol and isoflopanol are used as the astringent agents in alcohol, but when the use of ethanol is more than 20%, it can cause serious skin irritation. Therefore, there is a growing interest in convergence of natural products. Convergence of the skin to the skin is divided into two types: chemical convergence and physical convergence. The chemical convergence is inhibited by excessive substances such as tannin, Refers to the temporary contracting of pores, whereas physical convergence refers to the temporary shrinkage of sweat glands and pores by using cold water on the skin or by lowering the skin temperature by volatilization of ethanol. In cosmetics, astringents function to shrink the enlarged pores in the face area, and are used to temporarily tighten the skin by giving elasticity and pulling to give sensual satisfaction and make-up function. In addition to possessing moisture and moisturizing ingredients in the stratum corneum, it has convergence action and suppression of sebum secretion, has a refreshing feeling of use, and has a function of preventing the erasure of make-up.
In order to measure the skin convergence effect of the cambial plant cell culture extract obtained according to Example 1, blood protein (hemoglobin) similar to skin protein was used. Each sample solution and hemoglobin solution (500ppm) were mixed in a ratio of 1: 1, shaken, and centrifuged at 1,500 rpm for 3 minutes, and the absorbance was measured at 576 nm. The measurement of convergence effect was expressed by the absorbance reduction rate of the sample solution addition group and the no addition group.
