摘　　要：曲酸(KA)与4种金属离子配位反应得到相应的曲酸金属配合物KA-Fe(Ⅲ),KA-Cu(Ⅱ),KA-Mn(Ⅱ)和KA-Zn(Ⅱ),采用红外光谱、差热-热重分析和紫外光谱对其金属配合物进行了结构表征,并进行了对酪氨酸酶的抑制作用研究。结果表明,KA-Fe(Ⅲ),KA-Zn(Ⅱ)和KA-Mn(Ⅱ)对酪氨酸酶的抑制效果显著,对应的IC50为25,18和62μmol·L-1(曲酸IC50为70μmol·L-1),根据抑制机理分析,该系列金属配合物的抑制类型属于非竞争性抑制。Four kinds of metal complex of kojic acid（ KA）,KA- Fe（ Ⅲ）,KA- Cu（ Ⅱ）,KA- Mn（ Ⅱ） and KA- Zn（ Ⅱ） were prepared by complexing reaction through kojic acid and metal ion compounds. Their chemical structures were characterized by infrared spectra,differential thermal gravimetric analysis and ultraviolet spectra. Their tyrosinase inhibitory action was examined. Results showed that the tyrosinase inhibitory effect of KA- Fe（ Ⅲ）,KA- Zn（ Ⅱ） and KA- Mn（ Ⅱ） are remarkable. Their corresponding IC50 is 25,18 and62 μmol·L^-1respectively（ while IC50 of kojic acid is 70 μmol·L^-1）. Based upon analysis of their inhibitory mechanism,the type of inhibitory action of this series of compound is all considered as non- competitive inhibition.
