Three series of high molecular weight alkanoates found in Amazonian plants

An homologous series of α- and β-tocopheryl and phytyl alkanoates (C 12–C 24 acids) were characterized in the Amazonian plants Marupá ( Simaruba amara) and Brazil nut ( Bertholettia excelsa) by high temperature GC-MS. Electron impact mass spectra were measured by high temperature high resolution gas...

Description
Summary:An homologous series of α- and β-tocopheryl and phytyl alkanoates (C 12–C 24 acids) were characterized in the Amazonian plants Marupá ( Simaruba amara) and Brazil nut ( Bertholettia excelsa) by high temperature GC-MS. 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 α-tocopherol (vitamin E), β-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.
