A marine red alga, Porphyra tenera is one of the most important algae in Japan, and little has been known about its biochemical aspects. The present paper deals with the separation and identification of the nucleotides and their contents in the alga. The fresh sample laver was frozen and ground under liquid nitrogen. The nucleotide fraction was extracted from the ground laver with PCA, and separated by means of an activated charcoal, followed by fractionation by ion exchange chromatography, Dowex 1, Cl form being employed. The following nucleoside and nucleotides have been identified; Inosine, UMP, AMP, ADP, IMP, UDP, UDP-sugar, ATP, IDP, GTP and IDP-sugar ? or IDP-sugar-like substance. The sum of the contents of these identified was 0.69μmole/g•fresh. The contents of ATP, 0.21μmole/g•fresh, was the highest in all nucleotides and the next was ADP.
