Exploring Phylogenetic Relationships between Hundreds of Plant Fatty Acids Synthesized by Thousands of Plants. more details ...
Abstract The contents of fatty acids, amino acids, mineral elements, crude protein and crude fat were determined in the seeds of Kosteletzkya virginica, which was a fine salt-tolerant and oil plant. Methods of analysis of fatty acids and amino acids were GC-FID and HPLC, respectively. Toxic heavy metals (Cd, Pb) and other mineral elements were analyzed by ICP-MS and ICP-AES methods, respectively. The results showed the content of crude fat varied from 16.160% to 18.860%, with the mean of 17.536%. Nine fatty acids were detected, the majors of which were Palmitic acid, Oleic acid and Linoleic acid. The unsaturated fatty acids (70.134%) predominated over the saturated ones (29.866%). The crude protein content varied from 22.740% to 28.240%. The total content of 17 amino acids varied in the range of 17.084 g/100 g-18.939 g/100 g, with the high contents of glutamate, aspartic acid and arginine. The contents of Ca, K, Mg, Fe and Zn in the seeds of Kosteletzkya virginica were 2.708 g/kg, 9.487 g/kg, 3.888 g/kg, 146.633 mg/kg and 21.547 mg/kg based on dry-weight, respectively. These results suggested that the seeds of Kosteletzkya virginica studied represented a potential nutritive supply, and they could be used for oil, food, fodder, health care and industry.
