摘要

研究濒危藏药肉叶金腰内生真菌Cladosporium sp.J6次级代谢产物。采用硅胶、LH-20凝胶、C-18反相硅胶及HPLC等柱色谱技术对Cladosporium sp.J6的次级代谢产物进行研究；采用波谱分析及与文献比对等方法进行化合物结构鉴定；结果从肉叶金腰内生真菌Cladosporium sp.J6的发酵提取物中分离得到5个化合物，分别鉴定为alternariol (1)、alternariol 5-O-methyl ether (2)、β-咔啉(3)、尿嘧啶(4)和尿嘧啶核苷(5)。关于金腰属植物内生真菌次级代谢产物研究是首次报道。

Abstract

To study the secondary metabolites of endophytic Cladosporium sp.J6 from endangered Chrysosplenium carnosum from Tibet. The chemical constituents were isolated and purified by silica gel

Sephadex LH-20

ODS-18 column chromatography

and HPLC; their structures were identified by NMR and MS analysis

or comparison with literatures. Five compounds were isolated from the fermentation products of Cladosporium sp.J6; their structures were identified as alternariol (1)

alternariol 5-O-methyl ether (2)

β-carboline (3)

uracil (4)

and uridine (5). This report was about secondary metabolites of endophytic fungus from Chrysosplenium Tourn. ex L. for the first time.
