The volatiles emitted by agar plate cultures of the xylarialean fungus Hypoxylon invadens were investigated by use of a closed loop stripping apparatus in combination with GC–MS. Several aromatic compounds were found that could only be identified by comparison to all possible constitutional isomers with different ring substitution patterns. For the set of identified compounds a plausible biosynthetic scheme was suggested that gives further support for the assigned structures.
通过使用闭环蒸馏装置结合GC-MS,研究了木霉目真菌侵袭性低氧木属琼脂平板培养物释放的挥发性物质。发现了几种芳香化合物,只能通过与具有不同环替换模式的所有可能构成同分异构体进行比较才能确定其身份。针对已确定的化合物组合,提出了一个合理的生物合成方案,进一步支持了所确认的结构。
