Fifteen fatty acids were obtained from the mesocarp of this palm species. Oleic (72.7%) and palmitic (18.1%) acids were the predominant FAs. Minor FAs were cis-vaccenic acid (2.3%), linoleic acid (1.9%), stearic acid (1.7%), palmitoleic (0.9%) and alpha-linolenic acid (0.8%). The mean lipid content of the dry mesocarp was 51.6%. The O. bataua oil samples analyzed were remarkably rich in alpha-tocopherol. By contrast, the other fractions of the unsaponifiable matter (sterols, carotenoids) did not show any noteworthy specificity in comparison with common vegetable oils. However, the particularly high percentage in Delta 5-avenasterol of O. bataua oil could serve as a marker for its authentication. Results are discussed in terms of the potential nutritional value of O. bataua oil. specialized Amazonia Arecaceae Fatty acids Oenocarpus bataua Oil Sterols Carotenoids Tocopherols Unsaponifiable lipids 076 054 020 87 2 167-172 2010 0003-021X https://www.documentation.ird.fr/hor/fdi:010049272 10.1007/s11746-009-1490-4 0003-021X [F B010049272] https://www.documentation.ird.fr/hor/fdi:010049272 https://www.documentation.ird.fr/intranet/publi/2010/02/010049272.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-03-10 2017-08-23 fdi:010049272 fre
