上記方法で調製した試料2mLをプラスチック容器に加え、LED光源(CL-1501、朝日分光社製)を用いて6mW/cm2のブルーライト(430nm LED:、CL-H1-430-9-1、朝日分光社製)を10分間照射した。なお、実験は遮光下で行い、他の波長の光による影響を排除した。コントロールには原料水溶液の代わりに超純水を添加した。
5%ヒポタウリン水溶液20μLをヒト皮膚組織(KAC社、背中部)の角層側中央に適用し、遮光下で40分間静置した。
ブルーライト(430nm LED 6mW/cm2)を10分間照射し、その後ヒポタウリン水溶液を拭き取り、ただちに高感度冷却CCDカメラ(850S CCD42-40, Spectral Instruments Inc.)によって遮光下でUPEイメージングを行った(撮影時間 10分間)。
ラジカル消去率を評価することによって酸化抑制効果を測定する方法が知られている。よって、本発明者らは上記候補物質についてDPPH Antioxidant Assay Kit(DOJINDO LABORATORIES)を用いて以下の手順により、各候補成分の濃度ごとの酸化抑制効果を調べた。
2. Blank1、Blank2に水を20 μlずつ投入した。
3. 各wellにAssay Buffer 80 μlを加えた。
4. Blank2およびSample blankにエタノール100 μlを加え、ピペッティングでよく混ぜた。
5. SampleおよびBlank1にDPPH working solution 100 μlを加え、ピペッティングでよく混ぜた。
6. プレートを25℃、暗所で30分間インキュベートした。
7. プレートリーダーで517 nmの吸光度を測定(Spectramax 250、Molecular Devices社製)した。
8. Sampleのラジカル消去率(%)を以下の式3により算出した。
