Abstract
An aqueous solution of flavin mononucleotide (FMN) was photostabilized by addition of caffeine and purine bases. However it was destabilized by the addition of pyrimidine bases or p-cyclodextrin, which are generally known to stabilize dyes. Caffeine and purine bases supres s the decoloration of FMN by the formation of a complex with FMN. The fluorescence intensity of FMN decreased by addition of caffeine and purine bases but did not change by addition of pyrimidine bases of β-cyclodextrin. The difference UV spectra of FMN-caffeine complex had a peak at 493nm and this absorption peak was due to the pyrazine ring of FAIN: The quinone moiety of FMN molecule is considered to be covered by caffeine but not to be covered by pyrimidine bases or β-cyclodextrin.
