摘　　要：目的:合成槲皮素-钼配合物,推测配合物的结构。方法:将钼酸铵与槲皮素按物质的量比4∶3配比,在温度30℃pH2.0条件下作用6 h,合成槲皮质-钼配合物。通过元素分析、热分析、红外光谱、紫外光谱法测定配合物的结构和性质。结果与结论:紫外光谱显示在桂皮酰基处的3-羟基-4-酮基发生配合;红外光谱分析发现可能有水分子参与了配合;元素分析和热分析结果显示有11个H2O参与配合;等摩尔连续变化法和摩尔比法结果一致,确定槲皮素与钼是以物质的量比2∶1配合。配合物化学式推测为C30H22O16Mo.11H2O。Aim ：To synthesize the complex of quereetin and molybdenum,and to search the structure and characteriza- tion of the complex. Methods：The structure and character of the complex were determined based on methods of elemental analysis, thermal analysis, infrared spectrum and ultraviolet spectrum. Results and Conclusion ：The combination of quer- cetin and molybdenum predicted through ultraviolet spectrum might march on 3- hydroxyl-4-ketoyl near cinnamyl; the dis- play of infrared spectrum hinted that H20 involved in the combination; the results of elemental analysis and thermal analysis further demonstrated the quantity of H2Os was 11 ; equimolar series method and mole ratio method had the same conse- quence that the combination of molybdenum and quercetin was 2 ： 1. The chemical formula of complex of quercetin and mo- lybdenum may be C30H22O16Mo·11H2O.
