摘要:
A filamentous fangus Ascomyceters Hypocreaceae Hypomyces (Fr.) Ful SP. was obtained from the western mountainous area of Yunnan province of China,and cultured in the laboratory. A chemical component of the metabolite of the fungus had been identified as Elsinochrome A (EA) by UV spectrum,elemental analysis, MS, 1H NMR,13C NMR and X-ray analysis. Under appropriate condit ions,the chloroform solution of EA was mixed with the chloroform solution of dibenzylamine (DBA). Irradiation of the mixed compound with a visible-light exhibits stronger absorption as observed by a Varian E-115 ESR measurement. The results suggest that EA cause DBA to convert to oxynitride radical.
