| 摘 要： | 优化了超滤分离竹叶提取液中茶多酚(TP)的工艺条件,并进行了茶多酚在化妆品中应用的功能评价。通过正交试验得到超滤分离的最优工艺为:操作温度35℃,压力0.10 MPa,原料液质量浓度为0.21 mg.mL-1,pH=7。所得产品经生物活性试验研究表明,茶多酚对酪氨酸酶活性有明显的抑制作用和较强的清除DPPH自由基、羟自由基和超氧阴离子的能力,美白乳液中添加w(TP)=1.5%就能明显降低皮肤内黑色素含量。茶多酚可作为化妆品中的天然添加剂。

| Abstract: | Optimal conditions for separation of tea-polyphenols(TP) from extract solution of bamboo leaf by ultra filtration were identified,and the functions of application of tea-polyphenols in cosmetics were assessed on experimental basis.Through orthogonal designed tests,the optimal conditions were identified as follows:operating temperature 35 ℃,operating pressure 0.10 MPa,mass concentration of tea-polyphenols in the extract 0.21 mg·mL-1,and pH=7.Results of biological activity test of the TP showed that the TP displays significant inhibition effect on the activity of tyrosinase and excellent capabilities for scavenging DPPH free radicals,hydroxyl free radicals and superoxide anions.Addition of 1.5% TP(mass fraction) in whitening lotion is able to reduce the content of melanin in human skin significantly and displays excellent effect on human skin whitening.The TP can be used as natural additive in cosmetics. |
