— Differential fluorometry with sodium dithionite showed pterin‐like signals in extracts of Phycomyces sporangiophores. After iodine oxidation, pterin, biopterin and neopterin could be separated. The concentrations determined for these three pterins exceed the calculated minimal concentration of 3 times 10 −7 M for the photoreceptor.
