Description

【産業上の利用分野】
この発明は新規な化粧料、特に優れた美肌効果のあるキノコ抽出物を配合した化粧料に関するものであって、さらに詳しくはキコブタケ(Phellinus)属のキノコ好ましくはメシマコブ(P.yucatensis(Murr.)Imaz.)の天然の子実体、栽培された子実体及び菌床の抽出物に含まれる、美白・抗シワ・抗炎症・保湿効果すなわち美肌効果を有する物質を有効成分として含有する化粧料に関する。
【0002】
【従来の技術及び発明が解決しようとする課題】
メシマコブは抗腫瘍作用を持つことから、従来から健康食品または漢方薬として利用されている。しかし、その供給源としての天然の子実体は入手が難しく、また入手した後も、子実体の個体差による有用性の変動や量産化等実用面での問題点が多い。これらの問題点を回避すべく、メシマコブの菌糸を液体培養し、その培養液及び培養菌糸を入浴剤、頭髪料及び皮膚外用剤に利用することが知られている。一方近年になって、メシマコブの栽培方法が検討され、一定の条件下で子実体が得られるようになってきた。これにより、有効成分の含有率の高い子実体を安定的に入手することが可能になった。
【0003】
このメシマコブの栽培方法に関しては、特開平11−262329 、特開2000−236745等があるが、栽培し得られた子実体についての利用面、有効性等に関しては言及されていない。
【0004】
担子菌類は、胞子が発芽した後、糸状の菌糸が成長し、盛んに分岐して菌糸の網目集合体となった菌糸体を経て、更に塊に結合して分化した菌核となり、特定条件下で子実体を形成する。分化とともに細胞構造の上でも生理活性の上でも大きな違いが生じ酵素分布にも相違が見られるようになる。
【0005】
そのため、自ら栄養物を作り出すことの出来ない担子菌類は必然的に、菌糸や子実体自体に含まれる成分や代謝物は摂取する有機物の種類によって、また分化の段階によってもその種類や量が変動する。培養、栽培した場合は、培地組成の他に更に培養条件、栽培条件にも左右される。
【0006】
従って、液体培養により得られた菌糸と、菌床栽培によって得られた菌糸、菌糸の集合体である子実体とでは各々含有する成分も代謝物も大きく異なっていると考えられる。
【0007】
一方化粧料には、従来から皮膚科学に基づく各種成分が使用されている。例えば、美白成分として、L−アスコルビン酸及びその誘導体、ハイドロキノン、アルブチン、コウジ酸、システイン、グルタチオン、更に植物などの天然物の抽出物が化粧料に用いられている。抗シワ効果のある成分としては、α−ヒドロキシ酸、海藻抽出物、レチノール、ミカン科植物抽出物などが、抗炎症効果のある成分としては、グリチルレチン酸及びその誘導体、アラントイン、甘草抽出物などが用いられている。また、保湿成分としては、グリセリン、1,3−ブチレングリコール等の多価アルコール、アミノ酸やその誘導体、またヒアルロン酸、コンドロイチン硫酸、ケラト硫酸等の高分子ムコ多糖類やその誘導体、更に生体成分であるコラーゲン、エラスチン等のタンパク質が用いられている。これまで、美白及び抗シワ・抗炎症・保湿効果すなわち美肌効果を有する化粧料を処方化する場合、上記有効成分を何種類も組み合わせて、安定性、安全性、抗菌性とのバランスを取りながら、化粧料に配合してきた。しかし、1つの物質で美白・抗シワ・抗炎症・保湿効果等総合的に肌を美しくする美肌効果を期待できるものは少なかった。従って、1つの物質の配合によって、皮膚の美白効果に優れ、シミ、ソバカスの防止と共に、抗シワ効果、抗炎症効果を有し、保湿力も高く、且つ、安定性・安全性の良好な美肌化粧料の開発が望まれていた。
【0008】

【0021】
試料の調製
メシマコブ、キコブタケの天然の子実体、栽培された子実体、菌床抽出物、培養菌糸は、各々水で90〜95℃にて30分間抽出した。その後栽培された子実体、菌床抽出物、培養菌糸を乾燥し、更に99.5%エタノール溶液で60℃にて一晩侵漬し、抽出した。なお、天然のメシマコブ子実体は、長崎県男女群島女島にて採取した物を用いた。天然のキコブタケは、長野県の八ヶ岳山中にて採取したものを用いた。栽培したメシマコブ子実体は、以下の方法によって得られたものを用いた。最初に、上記天然の子実体から無菌的に切片を切除した。この切片をPotato−Dextrose
Broth(Difco社製)2.4%と寒天1.5%より調製したポテト・デキストロース寒天培地上に置き、24℃で2週間培養後、得られた菌糸を桑の原木に接種した。24℃で6ヶ月間培養後形成された子実体をメシマコブ子実体の栽培物とした。菌床は、桑のオガクズ、水、米ぬかより調製したオガクズ培地に、天然の子実体から上記の方法により分離した菌糸を接種後24℃で3ヶ月間培養し、培地中に菌糸が蔓延した状態のものを用いた。これら子実体の栽培物及び菌床は、(株)生物機能工学研究所(大阪市阿倍野区阪南町1丁目43番17号)より入手した。液体培養の菌糸は、グルコース15g、エビオス錠(田辺製薬(株))1.5gを馬鈴薯抽出液(馬鈴薯200gに水1500mlを加え煮沸後、ろ布ろ過し1500mlにフィルアップしたもの)に溶解後、pH6.0に調整し、120℃15分殺菌した30℃に冷却後、天然の子実体から上記方法により分離した菌糸を接種し、24℃で2週間通気攪拌培養して得られたものを用いた。上記抽出液を乾燥後、この乾燥エキスを1.0%濃度になるようにPBS(−)溶液に溶解し、試料とした。なお、菌糸培養液はこの抽出処理を行わなかった。陽性対照として用いたアルブチンは、市販の試薬を用いてPBS(−)溶液に溶解した。試料は全て、0.2μmメンブレンフィルターで除菌ろ過を行った。これらを用いて各種効果試験を行った。

メラニン産生抑制効果の測定
皮膚の黒化には色素のメラニンが深く関与していると考えられる。すなわち、メラニンが紫外線などの外的刺激を受けて肌の皮膚組織で生産され、その結果、肌の黒化が促進され、シミ・ソバカス・色黒等の症状が引き起こされると考えられている。よって、肌の美白作用の確認法としてメラニン産生抑制効果に着目し、今回、マウスメラノーマ細胞によるメラニン産生抑制試験を行った。
【0023】
細胞培養
培養液は、牛胎児血清5.0%を加えたダルベッコMEM(D−MEM)培地を用いた。細胞は、マウスメラノーマB−16
F−10を直径8cmのシャーレに植え付けた。植え付け量は4×10/cmとした。植え付けの翌日、調製した抽出物試料を乾燥物濃度にして表1の濃度になるよう添加を行い、添加後3日後に試験を終了した。
【0024】
評価方法
直径8cmシャーレに増殖した細胞をセルスクレーパーで集め、透明な遠心チューブに入れ3,000rpm、10分遠心し細胞を集めた。集まった細胞ペレットの色を肉眼判定し、5段階表示をした。
【0025】
(判定基準)
5:コントロールと比較してより黒い、4:コントロールと同じ、3:コントロールと比較してやや白い、2:コントロールと比較して白い、1:コントロールと比較してかなり白い
【0026】
表1にメラニン産生抑制効果試験の測定結果を示す。メシマコブ、キコブタケの子実体の天然物及び栽培物、菌床の抽出物は各試料とも、コントロール群及び比較対照として用いた培養菌糸抽出物、菌糸培養液に比べて高いメラニン産生抑制効果を認めた。

コラゲナーゼ活性阻害効果の測定
近年、老化に関する研究が進められ、皮膚老化の原因としては、第一には加齢が重要な因子であり、さらに紫外線による影響が皮膚老化に関わる直接的な因子として挙げられている。皮膚老化の具体的な現象としては、皮膚真皮におけるコラーゲンやエラスチンの減少、ヒアルロン酸をはじめとするムコ多糖類の減少、紫外線による細胞の損傷などが知られている。コラーゲンに関しては、コラゲナーゼ、即ちMMP−1(マトリックスメタロプロテアーゼ)が皮膚の真皮マトリックスの主な構成成分であるタイプI,IIIコラーゲンを分解する酵素として知られている。その発現は紫外線の照射により大きく増加し、コラーゲンの減少、変性の原因の一つとなり、皮膚のシワ形成等の大きな要因の一つであると考えられる。コラゲナーゼ活性を阻害することはコラーゲンを保護し、線維を形成するマトリックスを保護することとなり、皮膚の老化を防ぐうえで重要である。即ち、コラゲナーゼの活性を抑えて皮膚の線維成分を保護し、皮膚のハリ、弾力を回復・維持することで皮膚のシワ・タルミといった老化現象を防止し、若々しい肌の状態を維持することができる。よって、今回、メシマコブの抗シワ効果の確認法として、コラゲナーゼ活性阻害に着目し、MMP−1活性の測定を行った。
【0029】
細胞の培養
紫外線照射時に、ケラチノサイトから産生される物質により、線維芽細胞のMMP−1活性が促進される。よって、MMP−1活性の阻害効果を調べるため、以下の実験を行った。細胞は人胎児皮膚ケラチノサイト(Clonetic社)を用い、培地はGIBCO社のケラチノサイトSFM合成培地にて培養した。直径8cmのシャーレ(50cm)に人皮膚ケラチノサイト細胞をコンフルーエントになるまで培養した。コンフルーエントになった細胞に調製した試料を添加し、24時間培養した。培養後、培養液を捨てUV−B20mJ/cm照射した。その後、増殖因子添加物無添加のケラチノサイトSFM培地10mlで4時間培養し、その培養液を回収した。次に牛胎児血清15%を加えたHam’s F−12培地で正常人皮膚線維芽細胞を12wellシャーレに培養した。線維芽細胞がコンフルーエントになった時に培地を捨て回収した増殖因子添加物無添加のケラチノサイトSFM培地を1mlずつ12wellに添加し、48時間培養後、培養液のMMP−1活性を測定した。
【0030】
MMP−1活性の測定
MMP−1活性の測定は、12wellシャーレ(培地1ml)で48時間培養した線維芽細胞の培養液400μlを取り、4M−NaCl 40μlを添加し(株)ヤガイI型コラゲナーゼ活性測定キットにて活性型MMP−1の測定を行った。
【0031】
表2に各種試料のMMP−1活性測定の結果を示す。表2に示したように、紫外線照射により、MMP−1活性は62から120に上昇した。これに対して、メシマコブ、キコブタケの子実体の天然物及び栽培物、菌床の抽出物は各試料とも、紫外線照射のコントロール群及び比較対照として用いた培養菌糸抽出物、菌糸培養液に比べて高いMMP−1活性抑制効果を示した。

IgE抗体産生抑制効果の測定
アトピー性皮膚炎などにより代表されるアレルギー炎症において、マスト細胞から放出される、ロイコトリエンおよびトロンボキサンなどに代表される種々のケミカルメディエーターがアレルギー炎症反応に対し大きな役割を果たしていることが知られている。そしてこの反応は、免疫グロブリンE(IgE)抗体が細胞膜上の受容体に結合することがその原因となっている。このような状態においてアレルゲン等の刺激性物質が体内に侵入したとき、これが細胞膜上に結合したIgEに結合することによりケミカルメディエーターが放出され、アレルギー炎症を引き起す。事実アトピー患者等の血清中または組織中のIgE抗体の濃度は、健常人の当該濃度に比較して高い値を示すことが知られている。従ってIgE抗体の産生を抑えることができるならば、それによってアレルギー炎症の予防および/または治療に効果を発揮するものと考えられる。よって、肌の抗炎症効果の確認法としてIgE抗体産生抑制に着目し、IgE抗体産生量の測定を行った。陽性対照として用いたエピガロカテキンガレートは、市販の試薬100mgにジメチルスルホキシド(DMSO)を500μlとPBS(−)9.5mlを加えて溶解し試料溶液とした。
【0034】
細胞の調製
細胞はB細胞株であるU266細胞を用いた。培地はRPMI 1640培地に10mMのHEPES、1mMのピルビン酸ナトリウム、4.5g/lグルコース、1.5g/l炭酸水素ナトリウム、15%牛胎児血清を添加した培地で培養した。
【0035】
IgE産生量の測定
U266細胞を上記培地で培養し、5×10/mlの細胞を96wellに300μl/wellずつ植え付る。調製した試料を各種濃度添加し、37℃で24時間.培養した。培養後、660nmの吸光度を測定し、細胞増殖度とした。IgE量の測定は、(株)医学生物学研究所のMESACUP IgEテストを用いて行った。IgE産生度は細胞数当たりのIgE産生量をコントロール群と比較して算出した。

The present invention relates to a novel cosmetic, particularly a cosmetic containing an excellent skin-beautifying mushroom extract, and more particularly, a mushroom belonging to the genus Phellinus, preferably P. yucatensis (Murr.). The present invention relates to a cosmetic comprising, as an active ingredient, a substance having a whitening effect, an anti-wrinkle effect, an anti-inflammatory effect, a moisturizing effect, that is, a skin-beautifying effect, which is contained in extracts of natural fruit bodies, cultivated fruit bodies and fungus beds.
[0002]
[Prior art and problems to be solved by the invention]
Meshimakobu has been used as a health food or traditional Chinese medicine since it has an antitumor effect. However, it is difficult to obtain a natural fruit body as a supply source, and even after it is obtained, there are many problems in practical use such as fluctuations in usefulness due to individual differences of fruit bodies and mass production. In order to avoid these problems, it is known that the mycelium of Meshimakobu is subjected to liquid culture, and the culture solution and the cultured mycelia are used for bathing agents, hair preparations, and skin external preparations. On the other hand, in recent years, cultivation methods of Meshimakobu have been studied, and fruit bodies have been obtained under certain conditions. Thereby, it became possible to stably obtain fruit bodies having a high content of active ingredients.
[0003]
Regarding methods for cultivating Meshimakobu, there are JP-A-11-262329, JP-A-2000-236745, and the like, but there is no mention of the utilization aspect, effectiveness and the like of the fruit bodies obtained by cultivation.
[0004]
Basidiomycetes, after spores germinate, grow mycelial mycelia, go through actively branched mycelia that become mycelial mesh aggregates, and then bind to clumps and become differentiated fungal nuclei under specific conditions To form a child body. Along with differentiation, there is a big difference in cell structure and physiological activity, and there is a difference in enzyme distribution.
[0005]
For this reason, basidiomycetes that cannot produce their own nutrients inevitably have different types and amounts of components and metabolites contained in the mycelium and fruit bodies themselves depending on the type of organic matter consumed and the stage of differentiation. To do. In the case of culturing and cultivating, in addition to the medium composition, it also depends on the culturing and cultivation conditions.
[0006]
Therefore, it is considered that the mycelia obtained by liquid culture, the mycelia obtained by the mycelia cultivation, and the fruit bodies that are aggregates of mycelia have different components and metabolites.
[0007]
On the other hand, various ingredients based on dermatology have been used in cosmetics. For example, as a whitening component, L-ascorbic acid and its derivatives, hydroquinone, arbutin, kojic acid, cysteine, glutathione, and extracts of natural products such as plants are used in cosmetics. Anti-wrinkle ingredients include α-hydroxy acid, seaweed extract, retinol, citrus extracts, and anti-inflammatory ingredients include glycyrrhetinic acid and its derivatives, allantoin, licorice extract, etc. It is used. The moisturizing components include polyhydric alcohols such as glycerin and 1,3-butylene glycol, amino acids and derivatives thereof, high molecular mucopolysaccharides and derivatives such as hyaluronic acid, chondroitin sulfate, and keratosulfuric acid, and biological components. Some proteins such as collagen and elastin are used. Until now, when formulating cosmetics that have whitening and anti-wrinkle / anti-inflammatory / moisturizing effects, that is, skin-beautifying effects, combine various active ingredients to balance stability, safety and antibacterial properties. Has been blended into cosmetics. However, there are few things that can be expected to have a skin-beautifying effect that makes the skin beautiful, such as whitening, anti-wrinkle, anti-inflammatory, and moisturizing effects. Therefore, by combining one substance, it has excellent skin whitening effect, prevents spots and freckles, has anti-wrinkle and anti-inflammatory effects, high moisturizing power, and good stability and safety. Development of the fee was desired.

[0021]
Sample Preparation Natural fruit bodies, cultivated fruit bodies, fungus bed extracts, and cultured mycelium of Mushroom Cob, mushrooms were each extracted with water at 90 to 95 ° C. for 30 minutes. Thereafter, the cultivated fruiting bodies, fungus bed extract, and cultured mycelium were dried and further immersed in a 99.5% ethanol solution at 60 ° C. overnight and extracted. In addition, as a natural Meshimakobu fruiting body, the thing collected in the Nagasaki Prefecture Gender Archipelago Mejima was used. Natural mushrooms were collected from the Yatsugatake Mountains of Nagano Prefecture. The cultivated Meshimakobu fruiting body was obtained by the following method. First, a section was excised aseptically from the natural fruiting body. This section was converted to Potato-Dextrose.
It was placed on a potato dextrose agar medium prepared from Broth (manufactured by Difco) 2.4% and agar 1.5%, and cultured at 24 ° C. for 2 weeks. The fruit body formed after culturing at 24 ° C. for 6 months was used as a cultivated fruit body. The fungus bed was inoculated with mycelia isolated from natural fruit bodies in the sawdust medium prepared from mulberry sawdust, water and rice bran, and cultured at 24 ° C for 3 months. The thing of was used. The cultivars and fungus beds of these fruit bodies were obtained from Research Institute for Biofunctional Engineering (43-17, Hannan-cho, Abeno-ku, Osaka). The mycelium of liquid culture is dissolved in 15 g of glucose and 1.5 g of Ebios tablets (Tanabe Seiyaku Co., Ltd.) in a potato extract (boiled with 1500 ml of water after adding 1500 ml of water, filtered through a cloth and filled up to 1500 ml). , Adjusted to pH 6.0, sterilized at 120 ° C. for 15 minutes, cooled to 30 ° C., inoculated with mycelia separated from natural fruit bodies by the above method, and cultured by aeration and stirring at 24 ° C. for 2 weeks. Using. After the extract was dried, the dried extract was dissolved in a PBS (−) solution to a concentration of 1.0% to prepare a sample. The mycelium culture solution was not subjected to this extraction treatment. Arbutin used as a positive control was dissolved in a PBS (−) solution using a commercially available reagent. All samples were subjected to sterilization filtration with a 0.2 μm membrane filter. Various effect tests were conducted using these.
[0022]
Measurement of melanin production inhibitory effect It is considered that the pigment melanin is deeply involved in skin darkening. That is, it is considered that melanin is produced in the skin tissue of the skin by receiving external stimuli such as ultraviolet rays, and as a result, the blackening of the skin is promoted and symptoms such as spots, freckles, and darkness are caused. Therefore, focusing on the melanin production inhibitory effect as a method for confirming the skin whitening effect, a melanin production inhibition test using mouse melanoma cells was conducted this time.
[0023]
Dulbecco's MEM (D-MEM) medium supplemented with 5.0% fetal bovine serum was used as the cell culture medium. Cells are mouse melanoma B-16
F-10 was planted in a petri dish having a diameter of 8 cm. The planting amount was 4 × 10 3 / cm 2 . The day after planting, the prepared extract sample was added to a dry product concentration so as to have the concentration shown in Table 1, and the test was terminated 3 days after the addition.
[0024]
Evaluation Method Cells grown in a petri dish having a diameter of 8 cm were collected with a cell scraper, placed in a transparent centrifuge tube, and centrifuged at 3,000 rpm for 10 minutes to collect the cells. The color of the collected cell pellet was visually judged and displayed in five levels.

[0028]
Measurement of Collagenase Inhibitory Effect In recent years, research on aging has been promoted, and as the cause of skin aging, firstly aging is an important factor, and further, the influence of ultraviolet rays is cited as a direct factor related to skin aging It has been. Specific phenomena of skin aging are known such as a decrease in collagen and elastin in the skin dermis, a decrease in mucopolysaccharides including hyaluronic acid, and cell damage due to ultraviolet rays. With regard to collagen, collagenase, that is, MMP-1 (matrix metalloprotease) is known as an enzyme that degrades type I and III collagen, which is the main component of the dermal matrix of the skin. Its expression is greatly increased by ultraviolet irradiation, which is one of the causes of collagen decrease and degeneration, and is considered to be one of the major factors such as skin wrinkle formation. Inhibiting collagenase activity protects collagen, protects the matrix that forms the fibers, and is important in preventing skin aging. In other words, it suppresses the activity of collagenase to protect the fiber components of the skin, and restores and maintains the elasticity and elasticity of the skin to prevent aging phenomena such as skin wrinkles and tarmi, and to maintain a youthful skin condition. Can do. Therefore, this time, as a method for confirming the anti-wrinkle effect of Meshimakobu, focusing on collagenase activity inhibition, MMP-1 activity was measured.
[0029]
The substance produced from keratinocytes promotes MMP-1 activity of fibroblasts when the cells are irradiated with ultraviolet rays. Therefore, in order to investigate the inhibitory effect of MMP-1 activity, the following experiment was conducted. Human fetal skin keratinocytes (Clonetic) were used as the cells, and the medium was cultured in a keratinocyte SFM synthesis medium from GIBCO. Human skin keratinocyte cells were cultured in a petri dish (50 cm 2 ) having a diameter of 8 cm until they became confluent. The prepared sample was added to the confluent cells and cultured for 24 hours. After culturing, the culture solution was discarded and irradiated with UV-B 20 mJ / cm 2 . Thereafter, the cells were cultured for 4 hours in 10 ml of keratinocyte SFM medium to which no growth factor additive was added, and the culture solution was collected. Next, normal human skin fibroblasts were cultured in a 12-well petri dish in Ham's F-12 medium supplemented with 15% fetal calf serum. When the fibroblasts became confluent, the culture medium was discarded and the collected keratinocyte SFM medium without addition of growth factor was added to 12 wells in an amount of 1 ml and cultured for 48 hours, and then the MMP-1 activity of the culture was measured.
[0030]
Measurement of MMP-1 activity MMP-1 activity was measured by taking 400 μl of a culture solution of fibroblasts cultured in a 12-well petri dish (1 ml of medium) for 48 hours and adding 40 μl of 4M-NaCl, potato type I collagenase activity. Active MMP-1 was measured with a measurement kit.
[0031]
Table 2 shows the results of measuring MMP-1 activity of various samples. As shown in Table 2, MMP-1 activity increased from 62 to 120 by ultraviolet irradiation. On the other hand, the natural and cultivated fruit and fruit extract of Mishima Kobu, Mushroom, and fungus bed extract were compared to the cultured mycelium extract and mycelium culture solution used as a control group for UV irradiation and as a comparative control for each sample. It showed a high MMP-1 activity inhibitory effect.

[0033]
Measurement of IgE antibody production inhibitory effect In allergic inflammation represented by atopic dermatitis, various chemical mediators such as leukotriene and thromboxane released from mast cells play a major role in allergic inflammation reaction. It is known that This reaction is caused by the binding of immunoglobulin E (IgE) antibody to a receptor on the cell membrane. In this state, when a stimulating substance such as an allergen enters the body, it binds to IgE bound on the cell membrane, thereby releasing a chemical mediator and causing allergic inflammation. In fact, it is known that the concentration of IgE antibody in the serum or tissue of an atopic patient or the like shows a higher value than that of a healthy person. Therefore, if the production of IgE antibody can be suppressed, it is considered that it exerts an effect on the prevention and / or treatment of allergic inflammation. Therefore, focusing on IgE antibody production suppression as a method for confirming the anti-inflammatory effect of the skin, the amount of IgE antibody production was measured. Epigallocatechin gallate used as a positive control was dissolved in 100 mg of a commercially available reagent by adding 500 μl of dimethyl sulfoxide (DMSO) and 9.5 ml of PBS (−).
[0034]
Preparation of cells U266 cells, a B cell line, were used as cells. The medium was cultured in a RPMI 1640 medium supplemented with 10 mM HEPES, 1 mM sodium pyruvate, 4.5 g / l glucose, 1.5 g / l sodium bicarbonate, 15% fetal calf serum.
[0035]
Measurement of IgE production amount U266 cells are cultured in the above medium, and 5 × 10 5 / ml cells are planted in 96 wells at 300 μl / well. Various concentrations of the prepared sample were added and the temperature was 37 ° C. for 24 hours. Cultured. After culturing, the absorbance at 660 nm was measured to determine the degree of cell proliferation. The amount of IgE was measured using the MESACUP IgE test of the Institute of Medical Biology. The degree of IgE production was calculated by comparing the amount of IgE production per cell number with that of the control group.
