本研究主要利用簡易有機反應方法合成一系列(多羥基苯亞甲基)-(羥基苯)胺化合物,進一步以體外試驗進行抑制酪胺酸酵素的能力,並與維生素C及麴酸比較其美白的功效。 In this study we aim to originally synthesize a series of highly productive (polyhydroxy-benzylidene)-(hydroxy-phenyl)amines and observe their In vitro efficacy test for skin-whitening by the tyrosinase inhibition test.
