A fluorescent metabolite present in seven members of the genus Rhizopus was isolated. This compound appeared green before spray treatment and purple after spray treatment with p-anisaldehyde in visible light. Subsequent purification and structural elucidation of the isolated compound yielded 1-[2,6,10,14-tetramethyl-17-carbomethyl heptadecyl]-1-[2,6,10,14-tetramethyl-17-methanoyl heptadecyl]-benzene.
