Organ-specific patterns of pteridines in bufo viridis

1. 1. A comparative study of pteridine distribution in different organs of Bufo viridis larvae was made in order to investigate the existence of organ-specific patterns. 2. 2. By using column and paper chromatography, three drosoproteins, 2-amino-4-hydroxypteridine-6-carboxylic acid, xanthopterin, isoxanthopterin, bufochrome, 2-amino-4-hydroxypteridine, hynobius-blue, biopterin, sepiapterin and isosepiapterin were found. 3. 3. A scheme of pteridine biosynthesis in Bufo viridis larvae is proposed. 4. 4. The occurrence of specific patterns in the organs is discussed with respect to their various derivations from the germ layers. © 1967
