produced by a number of marine diatoms around the world yet are very easily oxidized during senescence to yield several isomeric allylic 9‐hydroperoxides. Elucidation of the electron ionization mass spectrometry (EIMS) fragmentation pathways of the trimethylsilyl (TMS) derivatives of the alcohols (obtained by reduction of the corresponding 9‐hydroperoxides) is essential for their characterization and quantification
C 25三不饱和高支化异戊二烯(HBI)烯烃是由世界各地的许多海洋硅藻生产的,但在衰老过程中很容易被氧化,生成几种异构的烯丙基9-氢过氧化物。阐明醇的三甲基甲硅烷基(TMS)衍生物(通过还原相应的9-氢过氧化物获得)的电子电离质谱(EIMS)裂解途径对于在天然样品中进行表征和定量至关重要。
