采用闭环气提装置对棒炭层壳的挥发性成分进行了收集和GC-MS分析。一些化合物很容易确定的比较测量库质谱和保留指数公布的数据,而其他化合物的参考合成是必需的。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8个立体异构体和使用纯手性固定相的气相色谱分析来确定相对和绝对构型。另一种新的天然产物是6-壬基-2H-吡喃-2-酮。还报道了合成挥发物的抗微生物和细胞毒性作用。
The volatiles from the fungus Daldinia clavata 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-2H-pyran-2-one. The antimicrobial and cytotoxic effects of the synthetic volatiles are also reported.
