Immunohistochemistry technology was used to evaluated tyrosine hydroxylase of DA synthesis. DA, 5-hydroxytryptophan(5-HT) and their respective metabolic products 3,4 -dihydroxyphenylacetic, homovanillic are also precisely quantified in this research by using high-pressure liquid chromatography with electrochemical detector. The main metabolism monoamine oxidase of DA was processed too. RESULTS:WD can increase the synthesis and the metabolism process of DA .

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.
