Electron impact mass spectra were measured by high temperature high resolution gas chromatography-mass spectrometry (HT-HRGC-MS) for three homologous series of high molecular weight compounds present in the Amazonian plants Marupá (Simaruba amara) and Brazil nut (Bertholettia excelsa). Based on their mass spectra, the compounds were identified as three wax ester series of alpha-tocopherol (vitamin E), beta-tocopherol and phytol (2,6,10,14-tetramethylhexadec-14-en-16-ol). The interpretations are supported by high resolution mass spectrometry and GC retention indices of authentic standards.
采用高温高分辨气相色谱 - 质谱联用仪（HT - HRGC - MS）测定了亚马逊植物马鲁帕（苦香樫木）和巴西坚果中存在的三个高分子量化合物同系物系列的电子轰击质谱。根据它们的质谱图，这些化合物被鉴定为α - 生育酚（维生素E）、β - 生育酚和叶绿醇（2,6,10,14 - 四甲基十六 - 14 - 烯 - 16 - 醇）的三个蜡酯系列。这些解释得到了高分辨质谱和标准品气相色谱保留指数的支持。
