Description

A skin-care agent containing the extract of Mycoleptodonoides aitchisonii fruit body}

The present invention relates to a composition for external application for skin containing a fruity body extract of true needle mushroom, and more particularly to a composition for external application for skin containing a filtrate obtained from a fruity body extract of true needle mushroom.

Skin aging can be divided into two types: intrinsic (chronological aging) and phtoaging (Gilchrest BA: J. Am . Acad . Dermatol ., 21, 610-613 (1989). Endogenous aging is a naturally occurring aging phenomenon that is accompanied by decreased physiological function of the body as age increases [Braverman IM et al . : J. Invest . Dermatol ., 78, 434-443 (1982)]. Photoaging means that the skin is repeatedly exposed to light to change the appearance or function of the skin [Ridder GM et al . : J. Am . Acad . Dermatol ., 25, 751-760 (1991)]. In addition, skin aging may be caused by the activation of free radicals with UV rays, stress, disease conditions, environmental factors, wounds, age, and when this condition is intensified, destroys the antioxidant defenses in vivo, cells and Damage to tissues promotes adult disease and aging. More specifically, lipids, proteins, polysaccharides and nucleic acids, which are major constituents of the skin, are oxidized to destroy skin cells and tissues, resulting in skin aging. In particular, the oxidation of proteins causes severe hyperinflammation of collagen, hyaluronic acid, elastin, proteoglycans, and fibronectin, which are connective tissues of the skin, which interferes with skin elasticity. Mutation, cancer induction, and immune function.

Therefore, it is necessary to protect the cell membranes by abolishing reactive oxygen species that are mediated by the body's metabolic processes, ultraviolet irradiation, and inflammatory reactions, and regenerate already damaged cells by active metabolism to proliferate the cells Can be restored and healthy skin can be maintained. In aging, not only active oxygen species but also MMP (Matrix metallopretease) is involved. In vivo, the synthesis and degradation of extracellular matrix such as collagen are properly regulated, but the synthesis is reduced as aging progresses and the collagen- Expression of matrix metalloproteinases (MMPs) is promoted, and skin elasticity is lowered and wrinkles are formed. Ultraviolet exposure also activates these degrading enzymes. Therefore, there is a demand for development of a substance capable of controlling the activation of MMP induced in the cell by ultraviolet light or inhibiting its activity. Until now, the raw materials used as cosmetic materials mostly inhibited only the activity of degrading enzyme (MMP).

On the other hand, melanin is converted from tyrosine to dopa and dopaquinone by the action of tyrosinase existing in pigment cells, and is generated by dopachrome. Melanin is present in the skin, protects the body from ultraviolet light and has an important function in regulating hormone secretion in the body. However, when melanin is overproduced, it is known that it forms spots and freckles, promotes skin aging, and plays an important role in skin cancer induction. Therefore, research and development are actively conducted to prevent melanin overproduction. (Japanese Patent Laid-open No. 4-93050) and plant extracts inhibit tyrosinase (Japanese Patent Laid-open Publication No. 4-9320), hydroquinone (Japanese Patent Laid Open No. 6-192062), kojic acid Activity and is used as a whitening cosmetic, but its stability is poor in cosmetic formulations, it is decomposed to cause coloration, odor, or efficacy at a biological level, its effect is unclear, or its safety is a problem. to be.

On the other hand, atopic dermatitis is a typical disease in people with atopic dermatitis. Although the cause of atopic dermatitis has not been clarified yet, 70% of patients with atopic dermatitis have a history of atopy, and in allergic people It is known to be one of the diseases caused by genetic factors and immune diseases because it is associated with allergic rhinitis, asthma, and other allergic diseases. In the treatment of atopic dermatitis, medicines such as corticosteroids, which can expect high pharmacological effects, are used, but side effects of corticosteroids are problematic, and the use of corticosteroids causes the rebound It is also well-known that a later severe worsening of the affected part occurs. As a countermeasure for such side effects, nonsteroidal anti-inflammatory drugs or antihistamines, which do not contain hormones such as corticosteroids, are used, but since it is difficult to cure, there is an urgent need to develop an atopic dermatitis improving agent or treatment without side effects.

Recently, in order to reduce skin irritation caused by various chemicals, much attention has been focused on functional cosmetics having functions such as antioxidant, wrinkle relief, whitening, and itching relief obtained from natural extracts. For example, U.S. Patent No. 5,972,341 discloses a wrinkle-reducing effect of an extract of Commiphora mukul. Japanese Patent Application Laid-Open No. 9-672662 discloses an extract of seaweed having a hyaluronidase inhibitory effect, Japanese Patent Application Laid-Open No. Hei 2-245087 discloses an antioxidative effect of Sargassum sp. Extract on the skin texture improvement effect of Fucoidan extracted from Wakame, Patent No. 0431076 discloses a cosmetic composition for improving the healing of atopic skin including a white, black, echinacea, and fermented soybean extract, Korean Patent No. 0511494 discloses an extract and composition for treating atopic dermatitis including at least one of Hashuo, .

In addition, androgenetic alopecia is directly dependent on the amount of androgen, which is dependent on androgen hormones. Accordingly, many studies have recently been reported for the prevention and treatment of hair loss through inhibition of androgen activity. On the other hand, when the function of the sebaceous gland is activated by the increase of the secretion of the male hormone, the excess sebum produced in the hair follicle is stagnated in the hair follicle due to the overgrowth of the hair follicle wall. 5-alpha-Reductase is one of the male hormones present in male hormone reactive tissues such as sebaceous glands, hair follicles, prostate, and epididymis, as a result of male hormone-induced hair loss and acne. , An enzyme involved in the metabolism of testosterone into dihydrotestosterone, and requires NADPH for its conversion. In addition, testosterone is involved in male sexual impulses, skeletal muscle increase, male external genitalia, scrotum growth, spermatogenesis, and the like, and dehydrotestosterone is involved in tissues such as acne, sebum increase, hair loss, and prostatic hyperplasia. In particular, after puberty, excessive secretion of male hormones causes acne and hair loss. To prevent excessive production of dihydrotestosterone, an active form of male hormone produced by 5-alpha-reductase, 5-alpha-reductase Studies have been actively conducted to develop anti-hair loss and anti-acne agents using an azide inhibitor.

In order to solve such skin problems, many cosmetics using natural products or medicinal and edible mushroom extracts have recently been developed to reduce skin irritation caused by various chemical substances and the like. As a cosmetic composition using the mushroom extracts known so far, there have been proposed a cosmetic composition comprising a mixture of a mushroom (Korean Patent No. 0340185), a mushroom, a skimmer mushroom (Korean Patent No. 0681703, No. 0076537), a mushroom (Korean Patent No. 0438009) And the research on the anti-aging effect of these extracts has been continued.

Mushrooms which are used for medicinal and edible purposes are many examples and kinds, but mushrooms which are used and studied as cosmetic composition are still known as a part.

On the other hand, Mycoleptodonoides It is a kind of edible mushroom which is called aurasin mushroom and is a fruit-flavored mushroom. The fruiting body has no mushroom sack. It has a soft meat quality and becomes strong when dried. Is shaped like a tooth. Mycelium is 2 hyphae of thick film and thin film. The bottom layer of fleshy layer is needle mushroom type, needle is pointed, length is 3 ~ 10 mm and becomes yellowish when dried. In addition to the pharmacological effects such as blood pressure strengthening action, blood sugar enhancing action, brain function improvement effect, anticancer and anti-diabetic action, it is expected to be excellent in nutrition. However, in Korea, . ≪ / RTI >
