摘　　要：以曲克芦丁为配体、Nd3+作为形成体制备曲克芦丁钕配合物,探索曲克芦丁与Nd3+反应生成配合物的适宜条件,通过紫外光谱、红外光谱、质谱等手段对其进行表征。结果表明:TXT中4-C=O的氧原子和5-OH的氧原子与Nd3+发生螯合生成Nd(TXT)2]3+,TXT与Nd3+反应的适宜条件为曲克芦丁与钕的物质的量之比为2∶1、p H=7.0、反应温度55℃、反应时间4 h。Serials experiments were carried out to found the optimal condition of the formation of troxerutin and Nd3＋. Finally, the complexes were characterized with ultraviolet（UV）, Fourier transferred infrared（FTIR） and mass spectroscopy methods. The experimental results indicate that Nd3＋ can form an 1∶2 complexes [Nd（TXT）2]3＋ with troxerutin via coordinated oxygen atoms on 4-carbonyl and 5-hydroxyl groups. The optimal process is that 2 mol troxerutin and 1 mol Nd3＋heated to 55 ℃ in neutral aqueous solution with stirring by 4 hours.
