Abstract
The acid-soluble nucleotides were extracted from the tubers of Jerusalem artichoke with perchloric acid, and separated and purified by means of adsorption on and elution from active charcoal, repeated chromatography on columns of Dowex 1 (CI-), followed by paper chromatography. The following nucleotides have been characterized and/or identified: 5'-AMP, 3'-AMP, ADP, ATP, 5'-GMP, 2'-GMP, 3'-GMP, 2', 3'-cyclic GMP, GDP, GTP, 5'-UMP, UDP, UTP, NADP, UDP-glucose, UDP-galactose, UDP-fructose, UDP-N-acetyl-hexosamine and GDP-mannose.** Neither cytosine ribonucleotides nor deoxyribonucleotides have been detected. The significance of these observations is discussed.
