Noteworthy among vitamin E derivatives are esters of dZ-=-tocopherol with higher fatty acids, individual representatives of which are of definite interest for medicine. Thus d~-etocopheryl linoleate (Ic), llnolenate (Id), and arachidonate (Ie) and the ester of dZ-e-tocopherol with 5,8,11,14,17-eicosapentaenolc acid, which have not only E-vitamln activity but also new biological properties, have been

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 Marupa (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. (C) 2002 Elsevier Science Ltd. All rights reserved.
