【産業上の利用分野】
この発明は新規な化粧料、特に優れた抗炎症効果を持つシンビジュームの抽出物と、メラニン産生抑制効果の高いクレマチス(Clematis)属、パッシフローラ(Passiflora)属、ビオラ(Viola)属、およびユーコミア(Eucommia)属植物から選ばれた抽出物を配合した化粧料に関するものである。 さらに詳しくはシンビジューム属に属するバルブ抽出物中に含まれるリポキシゲナーゼ抑制作用に基づく抗炎症効果を有する物質と、保湿効果を有する物質とを有効成分として含有することにより、肌荒れを抑制し、かつメラニン産生抑制成分としてクレマチス(Clematis)属植物、パッシフローラ(Passiflora)属植物、ビオラ(Viola)属植物、およびユーコミア(Eucommia)属植物の抽出物を配合して、日焼けなどによる皮膚の黒色化、シミ、ソバカスを防止、改善する化粧料に関する。
【0002】
【従来の技術】
紫外線などによって引き起こされる皮膚の炎症、黒化、シミ、ソバカスの防止・改善には、抗炎症剤および、チロシナーゼ抑制剤が使用されてきた。 抗炎症剤としては、グリチルレチンやその誘導体が使用されてきた。 このグリチルレチン類は、紫外線などの外的刺激を受けて皮膚組織中に生産される、アラキドン酸の代謝を抑制する作用がある。 すなわち、代謝産物であるロイコトリエン類や、プロスタグランジン類の産生を抑制し、これらアラキドン酸代謝物によって引き起こされる皮膚組織の傷害を予防するものである。 また、チロシナーゼ抑制剤としては、各種動植物からの抽出物を有効成分とするものが殆んどであり、一定の目的を達成できるとの記述が認められる。
【0003】
【発明が解決しようとする問題点】
しかしながら、これらグリチルレチンやその誘導体では、充分な効果は望めなかった。 一方、ステロイド剤は充分な抗炎症効果を発揮するが、連用後に重篤なリバウンド現象が起こり、安全性に大きな問題が生ずる。 また、肌荒れ状態の肌は、皮膚のバリアー機能が障害を受けており皮膚は乾燥状態にある。 そのため抗炎症剤だけでなく、他の保湿剤を添加し、皮膚の状態を改善する必要があった。
さらに、メラニン産生抑制剤に関しては、今までにも多種多様な物質の使用が提案されているが、メラニンの産生機序の複雑さを考慮し、他方、天然産物の多様性に着目すると、天然産物由来のさらなる多種多様な成分を利用する新規なメラニン産生抑制成分の提供が望まれる。 そこで本発明者等は安全性が高く、かつ充分な抗炎症効果を有すると共に、皮膚のバリアー機能を保護し、肌の黒化、シミ、ソバカスの防止・改善効果の高い化粧料を提供することにある。
【問題を解決する手段】
【0004】
本発明者等は、鋭意研究を重ねた結果、ラン科に属するシンビジューム属の抽出物が高いリポキシゲナーゼ抑制作用を有していることを見出した。 本発明におけるラン抽出液は、生体内でアラキドン酸の代謝に作用するリポキシゲナーゼの作用を抑制することにより抗炎症効果を有するものである。 また、それだけでなくシンビジューム植物体中に含有される糖質成分によって高い保湿効果を有する。 シンビジューム抽出物は結合水の割合が高く、乾燥状態においても水分を遊離しにくい性質を持つことが判明した。 したがって、リポキシゲナーゼの作用によって引き起こされる、アラキドン酸代謝物による皮膚組織の様々な炎症に対する改善効果だけでなく、炎症の結果生ずる肌荒れに対しても、その高い保湿作用により、荒れ肌状態の皮膚を改善する効果が期待できるものである。
【0005】
さらに、メラニン産生抑制成分としてクレマチス(Clematis)属植物の威霊仙(Clematis chinensis Osbeck.)抽出物、パッシフローラ(Passiflora)属植物のパッションフラワー(Passiflora incarnata L.)抽出物、ビオラ(Viola)属植物のワイルドパンジー(Viola tricolor L.ssp.Arvensis Murr.)抽出物、およびユーコミア(Eucommia)属植物の杜仲(Eucommia ulmoides Oliv.)抽出物に高い効果を見出した。 そして、これらメラニン産生抑制成分とシンビジューム属から抽出される成分を配合した化粧料は、抗炎症効果に優れるとともに保湿効果が高く、日焼けなどによる皮膚の黒色化、シミ、ソバカスを防止、改善する効果に優れたものであることを見いだし、本発明の完成にいたった。
【0006】
すなわち、本発明はラン科の属するシンビジューム属から得られた抽出物と、クレマチス(Clematis)属植物の威霊仙(Clematis chinensis Osbeck.)抽出物、パッシフローラ(Passiflora)属植物のパッションフラワー(Passiflora incarnata L.)抽出物、ビオラ(Viola)属植物のワイルドパンジー(Viola tricolor L.ssp.Arvensis Murr.)抽出物、およびユーコミア(Eucommia)属植物の杜仲(Eucommia ulmoides Oliv.)抽出物を含有することを特徴とする化粧料を提供するものである。 ここで、クレマチス(Clematis)属植物として威霊仙(Clematis chinensis Osbeck.)、パッシフローラ(Passiflora)属植物としてパッションフラワー(Passiflora incarnata L.)、ビオラ(Viola)属植物としてワイルドパンジー(Viola tricolor L.ssp.Arvensis Murr.)、およびユーコミア(Eucommia)属植物として杜仲(Eucommia ulmoides Oliv.)抽出物を例示したが、特にこの植物に限定されるものではない。
【0007】
本発明の化粧料に用いる前記シンビジューム抽出物、威霊仙抽出物、パッションフラワー抽出物、ワイルドパンジー抽出物、および杜仲抽出物の調製法は特に限定されないが、例えば種々の適当な有機溶媒を用いて低温下から加温下で抽出される。 抽出溶媒としては、例えば、水;メチルアルコール、エチルアルコール等の低級1価アルコール;グリセリン、プロピレングリコール、1,3-ブチレングリコール等の液状多価アルコール;アセトン、メチルエチルケトン等のケトン;酢酸エチルなどのアルキルエステル;ベンゼン、ヘキサン等の炭化水素;ジエチルエーテル等のエーテル類;ジクロルメタン、クロロホルム等のハロゲン化アルカン等の1種または2種以上を用いることが出来る。 就中、水、エチルアルコール、1,3-ブチレングリコールの1種または2種以上の混合溶媒が特に好適である。
【0008】
シンビジューム、威霊仙、パッションフラワー、ワイルドパンジー、および杜仲の抽出は生のまま、あるいは乾燥した植物体を重量比で1〜1000倍量、特に10〜100倍量の溶媒を用い0℃以上、特に20℃〜40℃で1時間以上、特に3〜7日間行うのが好ましい。
【0009】
以上のような条件で得られる抽出物は、抽出された溶液のまま用いても良いが、さらに必要により濾過等の処理をして、濃縮、粉末化したものを適宜使い分けて用いることが出来る。
【0010】
本発明の化粧料における各種抽出物の配合量は、蒸発乾燥分に換算して一般的に0.001〜20.0重量%が好ましく、特に0.01〜5.0重量%の範囲が最適である。 含有量が0.001重量%未満であると充分な効果が発揮されず、20.0重量%以上加えても効果はほぼ一定である。
【0011】
本発明の化粧料の剤形は特に限定されず、化粧水、乳液、クリーム、パック、パウダー、スプレー、軟膏、分散液、洗浄料等種々の剤形とすることができる。
こうして得られた抽出物は、毛髪用組成物または皮膚外用組成物(化粧料または薬剤)に常用されている希釈剤、アニオン性界面活性剤、非イオン性界面活性剤、カチオン性界面活性剤、両性界面活性剤、高級アルコール、油分、保湿剤、増粘剤、溶剤、使用性向上剤、防腐剤、酸化防止剤、金属イオン封鎖剤、紫外線防止剤、粉末、その他の活性物質、色剤、香料等を目的とする剤形に応じて適宜使用して製剤化することができる。
【0012】

【0014】
【実施例1】
植物抽出物の調製
前記各種乾燥植物体それぞれの5gに抽出溶剤100mlを加え、室温でときどき撹拌しながら7日間抽出し、濾過して各抽出液を得た。 これら各抽出液を減圧濃縮し、下記測定方法による、測定試料とした。
【0015】
【実施例2】
リポキシゲナーゼ抑制効果の測定
<測定原理>
アラキドン酸を基質とする反応によりプロスタグランデイン類、ロイコトリエン類が生成され生体に対する炎症作用を引き起こす。 そこで、アラキドン酸からロイコトリエン類への反応を促進する酵素である5-リポキシゲナーゼの反応生成物である5-HETEの生成量を測定し抗炎症効果の測定を行うものである。
(1)試料溶液の調製
シンビジューム属植物のバルブから得た抽出物を、エタノール水溶液により各種濃度に溶解したものを試料溶液として調製した。
(2)測定法
ラット由来好塩基球細胞株 RBL-1をFBS 10%を加えたイーグル MEM 培地で培養する。 培養後、細胞を採集し、PBS(+)溶液に1×107/mlの細胞を分散させた。 そこに試料溶液を50μl加え、37℃、5分間保温し、アラキドン酸 50μgとCaイオノフォア A 23187、1μg を加え、37℃、20分間インキュベートした。 その後、冷エタノール4mlを加えて反応を停止し、2000rpm、10分間遠心分離し、上清を減圧濃縮した。 残査をHPLC分析用の移動相30μlの溶解し、その 2μlを取ってHPLC分析を行った。
(3)HPLCによる分析
カラム:NUCLEOSIL 3 C 18
サイズ:6.0×150mm(6A)
検出 : UV 240 nm
溶媒 :CH3CN:MeOH:H2O:AcOH=350:150:250:1
流速 :1.0ml/min.で行い、PGB2(プロスタグランディンB2)を内部標準として使用した。 HPLCによる分析条件は、上記の条件で行った。 これら条件により、標準試薬およびRBL-1細胞を用いた試験系で反応を進行させた結果、標準試薬の5-HETEは12.8min.付近に、内部標準のPGB2は5.7min.付近に、ピークが認められた。 また、細胞系で反応させたアラキドン酸は、標準試薬の5-HETEと同じ位置にピークが認められた。
【0016】
表1にリポキシゲナーゼ抑制試験の測定結果を示す。
表1の結果から明らかなように、いずれの試料においてもリポキシゲナーゼ抑制作用を示している。 なかでも、エタノール溶液によるシンビジューム抽出物には、特に高い抗炎症効果があることが判明した。
【0017】
【表1】
【0018】
【実施例3】
保湿性試験
【測定法】
示差走査熱量測定装置(DSC)の試料パンに測定用試料を正確に測り取り、湿度0%下に3日間放置した後、試料の重量を測り乾燥重量とした。 さらに、湿度100%下に3日間放置し、試料の重量を測り吸湿重量とした。 吸湿重量から乾燥重量を引いた値を全水分量とした。 次に昇温速度15℃/min.で -50℃から20℃まで昇温し、その時に発生した熱量を0℃付近の水の有する熱量333mJ/mgで割った値を自由水量とした。 最後に、全水分量から自由水量を差し引いた値を結合水量とした。
【0019】
表2に保湿性試験の測定結果を示した。 表2の結果から明らかなように、シンビジューム抽出物は、対照試料のヒアルロン酸と比較して、高い結合水を含有していることが判明した。 なかでも50%エタノール抽出物にはヒアルロン酸の約9倍の結合水を含有でき、保湿効果が高いことが明らかとなった。

メラノサイトによるメラニン産生抑制効果の測定
つぎに威霊仙抽出物、パッションフラワー抽出物、ワイルドパンジー抽出物、および杜仲抽出物のメラニン産生抑制効果について、マウスメラノーマ細胞によるメラニン産生抑制試験について述べるが、ここに記載された実施例に限定されないのは言うまでもない。
【0022】
試料の調製
威霊仙抽出物、パッションフラワー抽出物、ワイルドパンジー抽出物、および杜仲抽出物をそれぞれ10mg、ポリオキシエチレン硬化ヒマシ油 5mg、牛胎児血清1mlを秤取し、良く溶解した後、ダルベッコMEM培養液10mlに加えた。 培養液を超音波処理により透明に溶解した後、除菌濾過を行い試料を調製した。
【0023】
細胞培養
マウスメラノーマ細胞 B-16 株を用いて、実験を行った。 培地にはダルベッコ MEM 培養液に牛胎児血清10%を添加した。 パッションフラワー抽出物は水抽出物、50%エタノール水溶液抽出物、100%エタノール抽出物を培地にそれぞれ100ppmの濃度になるように添加した。 また、美白効果の陽性対照物質としてコウジ酸を用いた。 メラニン量の測定は培養後細胞を2N-NaOHに溶解し、400nmの吸光度を測定した。 また、細胞数は2N-NaOHに溶解した細胞溶解液の一部を Bio-Rad 社のプロテインアッセイキットにより600nmの吸光度で測定し、タンパク量に換算した。 メラニン産生量は、単位タンパク量あたりのメラニン量の割合で計算した。
【0024】
実験結果
表 3にマウスメラノーマ B-16 細胞に及ぼす各植物抽出物のメラニン産生抑制効果を示した。陽性対照であるコウジ酸は、細胞毒性のかからない上限濃度である100ppm添加で22%のメラニン産生抑制度であった。 一方、パッションフラワー抽出物は、細胞毒性がかからない濃度の300ppm添加で水抽出物が53%、50%エタノール水溶液抽出物が46%、100%エタノール抽出物が38%のメラニン産生抑制効果であり、パッションフラワー抽出物に高い美白効果が認められた。 ワイルドパンジー抽出物は、細胞毒性のかからない300ppmの添加濃度で水抽出物が38%、50%エタノール水溶液抽出物が35%のメラニン産生抑制効果であった。 100%エタノール抽出物は細胞毒性のかからない100ppm添加濃度で25%のメラニン産生抑制効果であり、ワイルドパンジー抽出物には高い美白効果が認められた。 威霊仙抽出物は、100ppm添加濃度で水抽出物が51%、50%エタノール水溶液抽出物が22%、100%エタノール抽出物が15%のメラニン産生抑制効果であり、威霊仙抽出物に高い美白効果が認められた。 杜仲抽出物は、200ppm添加濃度で水抽出物が46%、50%エタノール水溶液抽出物が33%、100%エタノール抽出物が36%のメラニン産生抑制効果であり、杜仲抽出物に高い美白効果が認められた。

As an inhibitory ingredient, extracts of Clematis genus plant, Passiflora genus plant, Viola genus plant, and Eucommia genus plant are blended, and skin blackening due to sunburn, stains, The present invention relates to a cosmetic that prevents and improves buckwheat.
[0002]
[Prior art]
Anti-inflammatory agents and tyrosinase inhibitors have been used to prevent and ameliorate skin inflammation, blackening, spots, and freckles caused by ultraviolet rays. As an anti-inflammatory agent, glycyrrhetin and its derivatives have been used. These glycyrrhetins have the effect of inhibiting the metabolism of arachidonic acid, which is produced in the skin tissue under external stimuli such as ultraviolet rays. That is, it suppresses the production of metabolites leukotrienes and prostaglandins and prevents skin tissue damage caused by these arachidonic acid metabolites. Further, as tyrosinase inhibitors, most of them contain extracts from various animals and plants as active ingredients, and it is recognized that a certain purpose can be achieved.
[0003]
[Problems to be solved by the invention]
However, sufficient effects cannot be expected with these glycyrrhetin and its derivatives. On the other hand, the steroid agent exhibits a sufficient anti-inflammatory effect, but a serious rebound phenomenon occurs after continuous use, causing a serious problem in safety. Further, the rough skin is damaged in the barrier function of the skin, and the skin is in a dry state. Therefore, it was necessary to add not only anti-inflammatory agents but also other moisturizing agents to improve the skin condition.
Furthermore, regarding melanin production inhibitors, the use of a wide variety of substances has been proposed, but considering the complexity of the melanin production mechanism, while focusing on the diversity of natural products, It is desired to provide a novel melanin production-suppressing component using a wide variety of components derived from products.

[Example 3]
Moisturizing test [Measurement method]
A sample for measurement was accurately measured on a sample pan of a differential scanning calorimeter (DSC) and left for 3 days under 0% humidity, and then the weight of the sample was measured to obtain a dry weight. Furthermore, the sample was allowed to stand for 3 days under a humidity of 100%, and the weight of the sample was measured to obtain a moisture absorption weight. A value obtained by subtracting the dry weight from the moisture absorption weight was defined as the total water content. Next, the temperature was raised from −50 ° C. to 20 ° C. at a rate of temperature rise of 15 ° C./min., And the value obtained by dividing the amount of heat generated at that time by the amount of heat of 333 mJ / mg of water near 0 ° C. was defined as the free water amount. Finally, the value obtained by subtracting the free water amount from the total water amount was defined as the combined water amount.
