Abstract
An industrially advantageous process for producing an inosine-guanosine mixture having a higher weight ratio of guanosine/inosine than a starting mixture of nucleoside crystals and inosine subtantially free of guanosine from which comprises adjusting an aqueous fluid containing 10 to 30% by weight/volume of a nucleoside mixture to a pH of 9.1 to 9.5, wherein the total amount of inosine and guanosine is more than 95% by weight based on dry matters and the weight ratio of guanosine/inosine is 0.5 to 1, separating the resultant solids and then crystallizing inosine from the resulting solution.
