Abstract
The fatty acid composition of seed oil of Chrysophyllum albidum was determined by gas chromatography-mass spectroscopy (GC-MS). The seed oil contained much important fatty acids with linoleic (26.21%) and palmitic (14.41%) acids being the most abundant unsaturated and saturated fatty acids, respectively. The total unsaturation for the oil was 67.61%. These results confirm that the oil of C. albidum is of industrial importance. Key words: Chrysophyllum albidum, fatty acid, seed oil, methyl esters
Highlights
The fatty acid composition of the seed oil investigated revealed that the fatty acid range was from 12:0 to 20:1 (Table 2)
The saturated fatty acids comprised of lauric acid (12:0), palmitic acid (16:0) and stearic acid (18:0)
While the unsaturated fatty acid comprised of two monoenes namely: vaccenic acid (18:1) and eicosenoic acid (20:1), one diene: linoleic acid (18:2) and one triene: α-linolenic acid (18:3)
Summary
It is primarily a forest tree species and its natural occurrences have been reported in diverse ecozones in Nigeria, Uganda, Niger Republic, Cameroon and Cote d’Ivoire (Bada, 1997). Preliminary studies indicated that the oil was non-drying, based on its iodine value (Table 1) (Osamudiamen and Lukman, 2012). This paper is a report on the fatty acid constituents of the oil. The oil was extracted using soxhlet extractor with n-hexane for 8 h and the fatty acid profile of the seed oil was obtained as fatty acid methyl esters.
