摘要:

报道了从中国云南西部山区筛选到一株丝状真菌Ascomyceters Hypocreaceae Hypomyces (Fr.) Ful SP.,并在实验室成功地进行培养. 这株真菌代谢产物的化学组分是痂囊腔菌A(EA),并经紫外光谱、元素分析、MS、1H NMR、13C NMR和X-衍射鉴定. 在适当的条件下将痂囊腔菌素A(EA)氯仿溶液和二苄胺(DBA)氯仿溶液混合. 用可见光照射混合液,在Varian E-115ESR仪上可以得到强吸收. 得到的数据表明,EA可以诱导DBA转变成氧氮自由基.

Abstract:

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 conditions, 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.

Key words: ESR, Elsinochrome A, Photochemistry, Biosynthesis
