| 摘要 |
水晶冰花(Mesembryanthemum crystallinum)，又被称为ice plant。本发明揭露水晶冰花之水萃取物及松醇(水晶冰花主成份)可抑制皮肤细胞中生成黑色素(melanin)的酪胺酸酶(tyrosinase)活性，并抑制UV放射线对黑色素生成之促进效应。此外，水晶冰花之水萃取物及松醇可减缓UV放射线对皮肤细胞所造成的毒杀效应并抑制自由基生成。本发明揭露水晶冰花及松醇可应用于皮肤美白之产品。 Mesembryanthemum crystallinum, has also called as ice plant. This invention presented that the water extracts ofMesembryanthemum crystallinum(WEM) or which major compound, D-pinitol, could suppress tyrosinase activity to inhibit melanin production, and attenuated UV-ray-induced melanin generation in skinocytes. In addition, WEM or D-pinitol also attenuated the toxic effects and free radical levels in the UV-ray-treated skinocytes, suggesting that WEM or D-pinitol may be applied as “skin-whitening agent” |
