实验结果显示DNA对各配体及配合物的紫外吸收峰、各配体及配合物对DNA的紫外吸收峰都有着不同程度的影响。随着DNA的加入,配体的在230nm和290nm附近的紫外吸收峰逐渐减小,并产生红移现象。随着去甲斑蝥素酰胺酸的镧(Ⅲ)配合物的加入,DNA在260nm处的紫外吸收峰增强;去甲斑蝥素酰胺酸的钕(Ⅲ)配合物的加入,使得DNA在260nm处的紫外吸收峰减弱。而DNA的加入使得配体、配合物的荧光强度有或多或少的减弱。同时两种配体对EB-DNA体系的荧光具有猝灭作用,表明配体与EB争夺与DNA的结合位点,从而使体系中游离的EB增多。以上结果说明配体极有可能与DNA发生插入作用,而配合物与DNA的作用方式较复杂。

The experimental result shows DNA to each matching the body and cooperating with purple outside of the thing to absorb the peak , each matches the body and cooperates with things to have influence in various degree to absorb the peak on purple outside of DNA. With the joining of DNA, absorb the peak to reduce gradually purple outside near 230nm and 290nm to match the body, and the red phenomenon of moving emerges. As the lanthanum (¢ó ) going to the plain acyl amine and acid of first Chinese blister beetle cooperates with the joining of the thing , DNA absorbs the peak to strengthen purple outside of 260nm place ; Go to the plain acyl amine and sour neodymium (¢ó ) of first Chinese blister beetle to cooperate with the joining of the thing , make DNA absorb the peak to weaken purple outside of 260nm place . And what made the intensity of fluorescence matching the body , cooperating with the thing have more or less in joining of DNA subsided. At the same time it has sudden f
