摘　　要：以红茶提取物、绿茶提取物为考察对象,考察了红茶提取物和绿茶提取物的单独及联合应用的防晒、保湿、抗氧化、美白、抗衰老等功能,测试了二者在以上功能联合应用是否具有协同增效作用。结果表明,红茶、绿茶提取物在保湿、抗氧化、美白、抗衰老等功能上,联合应用比二者单独应用效果更强,其中2 g/L红、绿茶提取物混合物在抑制酪氨酸酶、弹性蛋白酶方面的联合指数CI仅为0.29和0.054,协同增效效果显著。The black tea extract and green tea extract was taken as the object of investigation.This experiment determined the functions of sunscreen,moisturizing,anti-oxidation,whitening and anti-aging of black tea extract and green tea extract alone and in combination,and whether the two have synergistic effects.The results showed that the combined application of black tea and green tea extracts had a stronger effect on moisturizing,anti-oxidation,whitening and anti-aging functions than the two alone.The combined index CI of 2 g/L black tea and green tea extracts mixture in inhibiting tyrosinase and elastase was only 0.29 and 0.054,showing a significant synergistic effect.
