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
通过使用闭环汽提装置收集来自真菌Daldinia clavata的挥发物,并通过GC-MS进行分析。通过比较库质谱图和保留指数与公开数据,可以轻松鉴定出几种化合物,而对于其他化合物,则需要合成参考文献。对于一种主要化合物5-羟基-4,6-二甲基辛-3--3-酮,其相对和绝对构型是通过合成所有八种立体异构体并使用同手性固定相进行气相色谱分析确定的。另一个确定的新天然产物是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。
