The structures of two blue-fluorescent substances, asperopterfn-A and -B, isolated from <I>Aspergillus oryzae</I> were investigated. Asperopterin-B was identified as 2-amino-3,4,7,8-tetrahydro-6-hydroxymethyl-8-methyl-4,7-dioxopteridine (<B>7</B>) by studying its chemical degradation, p<I>K</I><SUB>α</SUB> values, and UV spectra; the structure was confirmed by synthesis. Asperopterin-A was shown to be the β-D-ribofuranoside of <B>7</B>, 2-amino-3,4,7,8-tetrahydro-8-methyl-4,7-dioxo-6-pteridinylmethyl β-D-ribofuranoside (<B>10</B>).
