中文摘要：

利用分光光度法（UV）研究了不同摩尔比的Cu2＋与槲皮素的配合物生成过程,并采用多元分辨-交替最小二乘法（MCR-ALS）对实验数据进行分析.结果表明在中性条件下,Cu2＋与槲皮素只生成一种最终产物（吸收峰值为295nm）,中间经历了吸收峰值为438nm的过渡态.MCR-ALS分辨的结果为Cu2＋-槲皮素配合物的形成机理提供了理论依据.

英文摘要：

The reaction process of Cu2＋ and quercetin with different molar ratio were studied in this paper using ultraviolet-visible absorption spectroscopy（UV）.Experimental data were analyzed by multivariate curve resolution-alternating least squares（MCR-ALS）.It was shown that there were two products,intermediate product with the absorption peak at 438 nm and final product with the absorption peak at 295 nm.
