Abstract: 
A comparative study of substances fluorescing at 365 nm found in the skin and fins of xiphophorine fish [Platypoecilus maculatus, Xiphophorus helleri guentheri, X. montezumae cortezi and hybrids] was carried out by means of TLC and fluorometry. Groups of single xanthophores, xanthoerythrophores and melanophores were examined by means of micro cellulose thin layers. Fifteen spots could be found in thin-layer chromatographs. Nine compounds were identified as pteridines, 5 remained unknown, but may also be pteridines while one is riboflavin. The macropterinophore pattern controlled by the locus Dr (= dorsal red) and the macromelanophore pattern of Sd (= spotted dorsal) were investigated with regard to their pteridine content in 4 purebred strains and 6 hybrid genotypes. While some genotypes contain only the colorless pteridines: isoxanthopterin, ranachrome-3 and biopterin (limited pattern); others additionally possess the colored pteridines: neodrosopterin, drosopterin, isodrosopterin and sepiapterin (complete pattern). The amounts of pteridines found depend on the types and the numbers of chromatophores.
