Fatty Acid Profiles of Garuga floribunda, Ipomoea pes-caprae, Melanolepis multiglandulosa and Premna odorata Seed Oils

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 four 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 seed oils, except I. 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 G. floribunda contains minor amounts of a cyclic fatty acid (dihydrosterculic acid). © 2017, AOCS (outside the USA)

Fatty Acid Profiles of Some Fabaceae Seed Oils

The fatty acid profiles of six seed oils of the Fabaceae (Leguminosae) family are reported and discussed. These are the seed oils of Centrosema pubescens, Clitoria ternatea, Crotalaria mucronata, Macroptilium lathyroides, Pachyrhizus erosus, and Senna alata. The most common fatty acid in the fatty acid profiles of these oils is linoleic acid with palmitic, stearic, oleic and linolenic acids usually completing the most prominent fatty acids in these species. Long-chain saturated fatty acids were observed in all oils. Centrosema pubescens and Macroptilium lathyroides exhibited the greatest amounts of long-chain saturated fatty acids exceeding the amount of stearic acid in these oils. C. pubescens exhibited slightly more that 6 % C24:0 together with some fatty acids \u3eC25 and M. lathyroides approximately 4 % C22:0 and 3 % C24:0. The results are comparatively discussed to previous data on the fatty acid profiles of Fabaceae species. © 2016, AOCS (outside the USA)
