茶多酚的超滤分离及其在化妆品中的应用
Separation of tea- polyphenols by ultra filtration and its applications in cosmetics
摘要
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.关键词
