Description

本発明は、細胞賦活剤及び該細胞賦活剤を含有する皮膚の老化防止作用を有する皮膚外用剤に関する。   The present invention relates to a cell activator and a skin external preparation containing the cell activator and having an anti-aging effect on skin.

皮膚の表皮および真皮は、表皮細胞、線維芽細胞、およびこれらの細胞の外にあって皮膚構造を支持するコラーゲン等の細胞外マトリックスにより構成されている。若年の皮膚においては線維芽細胞の増殖は活発であり、線維芽細胞、コラーゲン等の皮膚組織の相互作用により水分保持、柔軟性、弾力性等が確保され、皮膚は外見的にもはりや艶があってみずみずしい状態に維持される。ところが、紫外線、乾燥等の外的因子の影響や加齢により、線維芽細胞の増殖が遅くなり皮膚等の保温機能や弾力性が低下する。そして、皮膚ははりや艶を失い、肌荒れ、皺等の老化症状を呈するようになる。   The epidermis and dermis of the skin are composed of epidermal cells, fibroblasts, and an extracellular matrix such as collagen that is outside these cells and supports the skin structure. In young skin, fibroblasts are actively proliferating, and skin retention such as fibroblasts and collagen ensures water retention, flexibility, elasticity, etc. There is a fresh state. However, due to the influence of external factors such as ultraviolet rays and drying and aging, the proliferation of fibroblasts is slowed, and the heat retaining function and elasticity of the skin and the like are lowered. The skin loses its elasticity and luster, and exhibits aging symptoms such as rough skin and wrinkles.

上記機構による皮膚の老化を防止・改善するために、線維芽細胞の賦活や増殖促進作用を有する成分として、ビワ抽出物、α−ヒドロキシ酸、6−ベンジルアミノプリン、プリムラ・シッキメンシス抽出物等が開示されている(特許文献1〜4)。しかしながら、上記成分等の中には、化粧料などに配合した場合の安定性及び安全性の点に問題がある場合もあることから、より安定性の高い、細胞賦活効果を有する素材が望まれていた。   In order to prevent / improve skin aging due to the above mechanism, loquat extract, α-hydroxy acid, 6-benzylaminopurine, Primula sickimensis extract, etc. are used as components having fibroblast activation and growth promoting action. (Patent Documents 1 to 4). However, some of the above components may have problems with stability and safety when blended in cosmetics and the like, and thus a material with higher stability and a cell activation effect is desired. It was.

一方、ラン科植物から得られた水溶性の抽出物を含有する化粧料やカトレヤの植物抽出物を含有する皮膚外用剤が提案されているが、これらの抽出物の細胞賦活作用についてはなんら記載されていない(特許文献5及び6参照)。   On the other hand, cosmetics containing water-soluble extracts obtained from orchidaceae plants and skin external preparations containing plant extracts of Cattleya have been proposed, but there is no description about the cell activation effect of these extracts. (See Patent Documents 5 and 6).

[参考例2 大豆抽出物の製造]
大豆の種子10gに、70vol%含水エチルアルコール100mLを加え、室温にて3日間抽出を行った後ろ過し、更に溶媒を除去して大豆抽出物0.05gを得た。
[Reference Example 2 Production of soybean extract]
To 10 g of soybean seeds, 100 mL of 70 vol% hydrous ethyl alcohol was added, extracted at room temperature for 3 days, filtered, and the solvent was removed to obtain 0.05 g of soybean extract.

[細胞賦活作用試験例]
24ウエルマイクロプレートに培地を適量とり、ヒト新生児由来の線維芽細胞を播種し、37℃、二酸化炭素濃度5%中にて静置した。翌日、参考例1で得たカトレヤ抽出物の最終濃度が0(対照)、2、20、200μg/mLとなるように試料を添加し混和した。培養4日目に培地を交換し、再度試料を添加した。翌日、5mg/mLになるように作製したMTT溶液を各ウエルにそれぞれ100μLずつ添加した。4時間培養したのち、培地を除去し、イソプロパノールを用いて生成したホルマザンを溶解した。マイクロプレートリーダーを用いてリファレンスを630nmとし570nmで吸光度を測定した。
また、比較例としてすでに細胞賦活作用のあることが知られている参考例2で得られた大豆抽出物についても同様の試験を行った。
各試料を添加して生育させた細胞数を対照の細胞数と比較し、その細胞増殖率を指標として細胞賦活効果を評価した。また、細胞数は、あらかじめ求めておいた細胞数と吸光度から検量線を作成し、その検量線から算出した。
[Cell activation test example]
An appropriate amount of the medium was placed in a 24-well microplate, seeded with fibroblasts derived from a human newborn, and allowed to stand at 37 ° C. in a carbon dioxide concentration of 5%. On the next day, the sample was added and mixed so that the final concentration of the Cattleya extract obtained in Reference Example 1 was 0 (control), 2, 20, and 200 μg / mL. On day 4 of culture, the medium was changed and the sample was added again. On the next day, 100 μL of the MTT solution prepared to 5 mg / mL was added to each well. After culturing for 4 hours, the medium was removed and the formazan produced using isopropanol was dissolved. The absorbance was measured at 570 nm using a microplate reader with a reference of 630 nm.
Moreover, the same test was done also about the soybean extract obtained by the reference example 2 already known to have a cell activation effect as a comparative example.
The number of cells grown by adding each sample was compared with the number of control cells, and the cell activation effect was evaluated using the cell proliferation rate as an index. The number of cells was calculated from a calibration curve prepared from the cell number and absorbance obtained in advance.
