Interpretive Summary: The oils that are found in the seeds of many plants consist mainly of so-called triacylglycerols. In turn, major parts of these triacylglycerols are fatty acids. The fatty acids comprising the triacylglycerols vary from oil to oil. These fatty acids are also responsible for the different properties these oils have, which then causes them to be suitable for different applications. Therefore, it is essential to know the fatty acid composition of such oils. This work reports on the fatty acids composing four tropical oils obtained from different plants known by their scientific names as Garuga floribunda, Ipomoea pes-caprae, Melanolepis multiglandulosa, and Premna odorata.

Technical Abstract: The fatty acid profiles of the seed oils of four species from four plant families for which no or only sparse information on the fatty acid profiles is available are reported. The five seed oils are Garuga floribunda of the Burseraceae family, Ipomoea pes-caprae of the Convolvulaceae family, Melanolepis multiglandulosa of the Euphorbiaceae family, and Premna odorata of the Labiatae (Lamiaceae) family. Linoleic acid is the most abundant in three of these seed oils, except Ipomoea pes-caprae in which oleic acid is most abundant. These two acids are overall the most abundant in all four seed oils studied. Of the four seed oils investigated, only Garuga floribunda contains minor amounts of a cyclic fatty acid (dihydrosterculic acid).
