Description

【0001】
【発明の属する技術分野】
本発明は、相乗的に増強された活性酸素種消去作用を有し、生体内外の酸化ストレスに起因する皮膚の老化防止や損傷を防止し得る皮膚外用剤に関する。更に詳しくは、ブナ属植物抽出物と、活性酸素種消去作用を有する成分とを併用して成る皮膚外用剤に関する。
【0002】
【従来の技術】
紫外線や生体内代謝により、体内には過酸化水素をはじめとしてヒドロキシラジカル,一重項酸素,スーパーオキシドといった活性酸素種が生じ、これらが生体に種々の悪影響を及ぼすことは良く知られている。特に、皮膚組織に関しては、かかる活性酸素種が皮膚脂質の過酸化だけでなく、しわ形成,真皮構成成分の変性等、皮膚の老化現象に深くかかわることが示唆されてきた。
【0003】
このような活性酸素種に起因する皮膚の老化,損傷を防止或いは改善するため、これらを消去する物質の検索が古くから行われており、ビタミンE群化合物や、茶タンニンなどの植物由来タンニン類、カロテノイド、又は他の動植物の抽出成分などが使用されている。
【0004】
しかしながら、従来用いられてきた活性酸素種消去剤は、安定性が悪かったり、消去作用が弱く不十分であったりして、特に複雑な処方系の皮膚外用剤に配合した場合、満足な効果の得られないものが多かった。
【0005】
【発明が解決しようとする課題】
従って、本発明は活性酸素種の消去作用を相乗的に高め、複雑な生体内における過酸化反応を有効に防止し、皮膚の老化及び損傷を効果的に防止又は改善し得る皮膚外用剤を得ることを目的とする。
【0006】
【課題を解決するための手段】
上記課題を解決するべく種々検討したところ、本発明者はブナ属植物の抽出物と、活性酸素種消去作用を有する植物抽出物或いは成分とを併用することにより、種々の皮膚外用剤に配合しても安定で、さらに活性酸素種消去活性が低下しないばかりか、相乗的に高められることを見いだし、本発明を完成するに至った。
【0007】
ブナ属植物の皮膚外用剤への応用としては、エタノール抽出物を有効成分とする上皮形成製剤(特公平4−33765号公報),ヨーロッパブナ抽出物を有効成分とする痩身剤(フランス特許第266228号公報),ブナ科ウラジロガシ抽出物を有効成分とする口腔用組成物(特開平6−298633号公報),ブナ科植物の種皮及び殻斗抽出物を抗酸化剤として含有する化粧料(特開平7−126618号公報),ブナの木の幼芽からの抽出物のケラチノサイト蛋白合成促進作用(特開平9−227397号公報)等がすでに開示されている。今回、ブナ属植物抽出物と、活性酸素種消去作用を有する植物抽出物或いは成分を併用することにより、生体組織,特に皮膚組織における活性酸素種消去作用が相乗的に高められることが見いだされた。かかる相乗作用の得られる機序は明らかではないが、それぞれの活性酸素種消去作用の安定化,生体内の連鎖的な酸化反応における消去作用の増強などが考えられる。

【0026】
【作用】
本発明の作用を示すために、まず各種植物抽出物の製造例を示す。
【0027】
[製造例1〜10]
各植物の表1に示した部位500gを、表1に示した溶媒1000mlに浸漬し、室温で一週間静置することにより抽出した。その後、植物体を濾別除去し、溶媒を減圧留去した後、得られた固形分を各溶媒にて再溶解して50mlとし、製造例1〜8を得た。

ブナ属植物抽出物と、活性酸素種消去作用を有する成分を併用した場合の、紫外線による細胞傷害に対する防御効果を次に示す。
【0030】
マウスケラチノサイトを喜多野等による修正MCDB153培地にて37℃で24時間培養した後、リン酸緩衝塩溶液にて2回洗浄後、ハンクス緩衝液に交換して、表2及び表3に示す各試料をそれぞれ添加し、FL−20S・Eランプを光源として300mJ/cm2の中波長紫外線(UVB)を照射した。照射後、ケラチノサイトをMCDB153培地中で37℃で24時間インキュベートし、ニュートラルレッド法により細胞生存率を求め、UVBを照射しない対照培養系の生存率を100%として、各試料を添加した場合の生存率を表し、表2及び表3に示した。
【0031】
【表2】
Figure 0003849269
【0032】
【表3】
Figure 0003849269
【0033】
表2及び表3に示したとおり、ハンクス緩衝液に交換した後、活性酸素種消去剤を添加しないでUVBを照射した場合(試料25)は対照培養系の47.2%まで細胞生存率が落ち込むことが認められ、ヨーロッパブナ抽出物を添加した試料11でも46.8%の細胞生存率であり、ヨーロッパブナ抽出物単独では防御効果が認められなかった。また、ハマメリタンニン又は製造例2〜製造例10をそれぞれ単独で添加した試料14〜試料25においては、細胞生存率の上昇は認められるものの、十分な上昇は得られていない。一方、製造例1のセイヨウブナ抽出物と、ハマメリタンニンなどの活性酸素種消去剤の双方を添加した試料(試料1〜試料13)においては、細胞生存率の大幅な回復が認められており、特にヨーロッパブナ抽出物と、ハマメリタンニンと、各種植物抽出物を併用した試料11〜試料13においては、95%以上の高い細胞生存率を示した。
【0034】
【実施例】
さらに本発明の特徴について、実施例により詳細に説明する。
【0035】
次に示す処方にて、皮膚用クリームを調製した。処方中の有効成分については、表4に示した。
Figure 0003849269
製法:(1)〜(5)を混合後加熱溶解して75℃とし、これに混合,加熱溶解して75℃とした(6)〜(9)及び(12)を添加して乳化し、冷却後40℃にて(10)及び(11)を添加,混合する。

本発明の上記実施例について、皮膚の老化防止効果を皮膚のしわ発生に対する防止効果を評価することにより検討した。ヘアレスマウスに長波長紫外線(UVA)を照射するとしわの発生が促進されるが、このUVAによるしわ発生に対する防止効果を評価した。ヘアレスマウス5匹を1群とし、各群について実施例及び比較例をそれぞれ1日1回背部に塗布し、1J/cm2/週のUVAを50週間照射し、ヘアレスマウスにおけるしわの発生状況を観察し、表5に示す判定基準に従って点数化して行った。この際、精製水のみを塗布した群を対照とし、比較例としては、上記皮膚用クリーム処方中の有効成分のかわりに、表6に示す成分を配合したものを用いた。結果は各群の平均値を算出し、UVA照射日数との関係により表7及び表8に示した。
【0038】

【表8】
Figure 0003849269
【0042】
表7及び表8に示されるように、対照群においては、UVA照射日数が40週を越える頃には形成されたしわの深さが中程度にまで達し、50週後には深いしわの発生が認められていた。これに対し、本発明の実施例塗布群では、いずれにおいても50週後に微小なしわが認められた程度で、しわの発生は顕著に抑制されていた。一方、有効成分として、セイヨウブナ抽出物或いはハマメリタンニンなどを単独で含有する比較例塗布群では、しわの発生防止効果は認められるものの、実施例塗布群に比較してはるかに小さく、殆どのマウスで軽微なしわの発生が認められていた。
【0043】
さらに、上記の本発明の実施例1〜実施例13及び比較例1〜比較例12について、使用試験を行った。使用試験は、日常戸外で作業するパネラー10名を一群とし、各群にそれぞれ実施例及び比較例をブラインドにて顔面及び手に使用させ、しわ及び皮膚弾性の変化を観察し、表9に示す基準にて評価して行った。使用期間は4月〜3月の1年間とした。結果は、平均値を算出し、表10に示した。
【0044】
【表9】
Figure 0003849269
【0045】
【表10】
Figure 0003849269
【0046】
表10において、有効成分を含有しない比較例1使用群では、しわの増加と皮膚弾性の低下が認められている。これに対して、本発明の実施例使用群では、しわの減少及び皮膚弾性の明確な上昇が認められていた。一方、ブナ抽出物及びハマメリタンニンなどの活性酸素種消去剤のみを含有する比較例2〜比較例12使用群では、比較例1に比べてしわの増加や皮膚弾性の低下に対する防止効果は認められるものの、これらに対して顕著な改善傾向を示すには至っていなかった。
【0047】
なお、本発明の実施例使用群において、使用試験期間中皮膚刺激性や感作性を認めたパネラーはいなかった。

【発明の効果】
以上詳述したように、本発明により、活性酸素種消去作用が相乗的に増強され、生体内外の酸化ストレスに起因する皮膚の老化や損傷を防止し、更に有効に改善しうる皮膚外用剤を提供することができた。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an external preparation for skin that has a synergistically enhanced action of eliminating reactive oxygen species and can prevent skin aging and damage caused by oxidative stress inside and outside a living body. More specifically, the present invention relates to an external preparation for skin comprising a combination of a beech genus plant extract and a component having an action of eliminating reactive oxygen species.
[0002]
[Prior art]
It is well known that active oxygen species such as hydroxyl radical, singlet oxygen, and superoxide are generated in the body due to ultraviolet rays and in vivo metabolism, and these have various adverse effects on the living body. In particular, regarding the skin tissue, it has been suggested that such reactive oxygen species are deeply involved in not only skin lipid peroxidation but also skin aging such as wrinkle formation and dermis component degeneration.
[0003]
In order to prevent or improve skin aging and damage caused by reactive oxygen species, search for substances that eliminate them has been conducted for a long time. Vitamin E group compounds and plant-derived tannins such as tea tannins , Carotenoids, or other animal and plant extracts are used.
[0004]
However, the reactive oxygen species scavengers that have been used in the past have poor stability, and the scavenging action is weak and insufficient. There were many things that could not be obtained.
[0005]
[Problems to be solved by the invention]
Therefore, the present invention synergistically enhances the action of scavenging reactive oxygen species, effectively prevents peroxidation in a complex living body, and obtains a skin external preparation that can effectively prevent or improve skin aging and damage. For the purpose.
[0006]
[Means for Solving the Problems]
As a result of various studies to solve the above-mentioned problems, the present inventor formulated a beech genus plant extract and a plant extract or component having an action of eliminating reactive oxygen species into various skin external preparations. However, the present invention has been found to be stable and not only to reduce the active oxygen species elimination activity but also to increase synergistically, thereby completing the present invention.
[0007]
As an application to the skin external preparation of a beech genus plant, an epithelial preparation containing an ethanol extract as an active ingredient (Japanese Patent Publication No. 4-33765), a slimming agent containing a European beech extract as an active ingredient (French Patent No. 266228) No.), a composition for oral cavity containing a beech family radish extract as an active ingredient (Japanese Patent Laid-Open No. Hei 6-298633), a cosmetic containing a seed coat of beech plant and a shell fungus extract as an antioxidant (Japanese Patent Laid-Open No. 7-126618), keratinocyte protein synthesis promoting action of an extract from beech tree buds (Japanese Patent Laid-Open No. 9-227397) and the like have already been disclosed. This time, it has been found that the combined use of a beech genus plant extract and a plant extract or component having a reactive oxygen species scavenging action synergistically enhances the reactive oxygen species scavenging action in living tissue, particularly skin tissue. . The mechanism by which such synergistic action is obtained is not clear, but stabilization of each reactive oxygen species scavenging action and enhancement of scavenging action in a chain oxidation reaction in vivo can be considered.
