中文摘要：

本文合成了槲皮素铬（Ⅲ）配合物,采用红外、紫外、热分析及元素分析等方法对其结构进行了表征,并研究了配合物清除羟基自由基、超氧阴离子自由基和DPPH自由基的活性.研究结果表明,配合物的分子式为[Cr（C15H9O7）2Cl·H2O]·7H2O,配合物较配体具有更强的清除羟基自由基、超氧自由基和DPPH自由基活性.

英文摘要：

Having synthesized the complex Cr（Ⅲ） - quercetin（[Cr（C15H9O7）2Cl·H2O]·7H2O） and characterized it with the methods of IR spectra, UV- spectra, thermal analysis and elemental analysis etc., the free radical （·OH,·O2, DPPH·） scavenging activities of the complex were investigated in this paper. The results showed that free radical scavenging activities of the complex on OH·, O2· and DPPH ·were obviously stronger than that of the quercetin.
