卟啉在生命机体的新陈代谢中扮演重要角色。本文研究了在室温条件下不同溶剂中卟啉的荧光光谱,发现在N,N-二甲基甲酰胺中卟啉荧光信号强且稳定,同时基本上不受离子强度的影响。N,N-二甲基甲酰胺亦能很好的萃取血样中的卟啉,是一种适合于血样卟啉荧光分析的新型溶剂。 Porphyrins play an important role in the metabolism of living organisms. Fluorescence spectra of porphyrins in different solvents at room temperature were studied in this paper. It was found that the fluorescence signal of porphyrin in N, N-dimethylformamide was strong and stable, while it was not affected by the ionic strength. N, N-dimethylformamide also can well extract porphyrin in blood sample, which is a new solvent suitable for fluorescence analysis of porphyrin in blood sample.
