美国白蛾性信息素中两主要成分的质谱研究

Study on the Two Pheromone Compounds of Hyphantria Cunea by Mass Spectrometry

摘要: 人工合成美国白蛾性信息素的两个主要成分即 (9z,1 2 z) -十八碳二烯醛 I及 (9z,1 2 z,1 5 z) -十八碳三烯醛 ,应用 GC/MS证实其结构。依照 EI谱分子裂解的主要特征碎片 ,讨论了两个分子的具体裂解途径

Abstract: Two pheromone compounds of Hyphantria cunea, (9 z,12 z)-octadecadienal Ⅰ and (9 z,12 z,15 z)-octadecatrienal Ⅱ, are identified by GC/MS. The fragment routes of characteristic are discussed on the basis of EI mass spectra.
