1956 Jrnl. Biochem. (Tokyo) 43 643 To estimate the fluorescence of flavin separately from similar fluorescent substances in living body, the procedure of converting flavins to lumiflavin is of excellent one [sic].
1962 S. Udenfriend Fluorescence Assay vii. 243 Riboflavin can also be converted to the more highly fluorescent derivative, lumiflavin, by photodecomposition in alkaline solution, the formation of lumiflavin involving cleavage between the ribitol and flavin ring.
