Eremothecium ashbyiiの菌体から分離されたG化合物(クロマトグラフィーの応用 第29報)

抄録

Detailed explanation was made on the isolation of G compound from the mycelium of Er. ashbyii, and its purification. The composition of this compound was established as C₁₃H₁₈O₆N₄. A key compound for elucidating the structure of G compound was isolated as yellow needles, m.p. 340∼345°(decomp.), from the photochemical decomposition products of the latter, and it was identified as 6, 7-dimethyllumazine from its Rf value and ultraviolet and infrared spectra. From these facts and from the analysis of the infrared spectrum of G compound, the structure shown was assigned to the compound.[chemical formula]
