|September 24, 1976
Abstract:
2-Amino-4-hydroxypteridine compounds were isolated as the Crithidia factor from spinach chloroplasts by DEAE-Sephadex A-50, DEAE-cellulose, Sephadex G-25, and thin-layer chromatography. One of the compounds was characterized as 6-hydroxymethylpterin by gas-liquid chromatography-mass spectrometry and by comparison with authentic specimen.
