This research utilized the method of organic synthesis, researching different amounts and positions of hydroxy-substituted benzoic acid and serotonin into amide reaction, so as to produce a series of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10). Accordingly, this study conducts the following four tests. I. The activity of antioxidant and the experiment of ability to scavenge DPPH free radical, II. The ability of overall antioxidant—the activity of TEAC, III. The activity test of inhibit Tyrosinase, and IV. The study of absorbing UV / VIS Spectrophotometers. This study use trolox, arbutin, and octyl salicylate as the control groups, and to test the ability of anti-oxidation, the activity of inhibit Tyrosinase, and the ability of absorbing UV. This research ultimately intends to investigate the applied value of those compounds into cosmetics.

本研究主要利用有机合成的方法，将不同数量及不同位置的羟基取代苯甲酸化合物与色洛冬宁进行醯胺化反应后，得到一系列的多羟基取代之N-色洛冬宁苯甲醯胺衍生物（化合物1 ~ 10），进行四种不同活性测试方法：一、清除DPPH自由基能力抗氧化活性测试；二、总抗氧化能力活性测试；三、抑制酪胺酸酶活性美白测试；四、紫外线／可见光光谱仪吸收测试，并以水溶性维生素E、熊果素、水杨酸辛酯当作对照组，探讨其抗氧化能力、抑制酪胺酸酶的活性能力与吸收紫外线能力，再进一步探讨其应用於化妆品上的价值。
