The seed oils of seven Trifolium species (Leguminosae) were investigated
for their protein, tannin contents and fatty acid compositions. The
fatty acid compositions of these seven different species were determined
by gas chromatography of the methyl esters of their fatty acids. The
seed protein contents were found to be between 23.57 and 36.60\%. The
seed tannin contents were found to be between 0.77 and 1.73\%. The seed
oils of Trifolium species contain palmitic and stearic acids as the
major component fatty acids, among the saturated acids, with a small
amount of myristic, pentadecanoic, arachidic and behenic acids. The
major unsaturated fatty acids found in the seed oils were oleic,
linoleic and linolenic acids. In this study, Total Saturated Fatty Acids
(TSFA) of Trifolium species were between 18.5 and 24.4\% while Total
Unsaturated Fatty Acids (TUSFA) were between 71.1 and 80.3\%. The
results revealed that the seed oils of Trifolium species studied with a
substantial amount of very long chain fatty acids might have attracted
attention because of their value of nutritional, industrial and
renewable resources.
