Abstract

The volatiles from the fungus were collected by use of a closed-loop stripping apparatus and analysed by GC-MS. A few compounds were readily identified by comparison of measured to library mass spectra and of retention indices to published data, while for other compounds a synthesis of references was required. For one of the main compounds, 5-hydroxy-4,6-dimethyloctan-3-one, the relative and absolute configuration was determined by synthesis of all eight stereoisomers and gas chromatographic analysis using a homochiral stationary phase. Another identified new natural product is 6-nonyl-2-pyran-2-one. The antimicrobial and cytotoxic effects of the synthetic volatiles are also reported.

摘要

使用闭环萃取装置收集真菌挥发物,并通过气相色谱 - 质谱联用仪(GC - MS)进行分析。通过将测得的质谱与谱库质谱以及保留指数与已发表数据进行比较,一些化合物很容易被鉴定出来,而对于其他化合物,则需要综合参考资料。对于主要化合物之一5 - 羟基 - 4,6 - 二甲基辛 - 3 - 酮,通过合成所有八种立体异构体并使用手性固定相进行气相色谱分析来确定其相对和绝对构型。另一种鉴定出的新天然产物是6 - 壬基 - 2 - 吡喃 - 2 - 酮。还报道了合成挥发物的抗菌和细胞毒性作用。
