摘要：The present studies were made to elucidate whether the enzymic formation of inosinic acid from various raw materials was possible. 1. The preparation of crystalline Ba-inosinate was attempted from whale or rabbit muscle by the Astern's method, and pure Na-salts were prepared by ion-exchange chromatography. 2. Concerning with the investigation on the natural sources for the inosinic acid formation, it was confirmed that adenine, hypoxanthine, guanine, xanthine, uracil, and thymine were widely distributed in biological materials. 3. Finally, the enzymic formation of nucleosides and nucleotides was carefully tested with animal tissue homogenate, and the formation of inosine and inosinic acid from hypoxanthine and D-ribose was realized with paper chromatography using rat-liver or shellfish homogenate.
