海滨锦葵种子营养成分分析

为合理开发利用耐盐油料植物海滨锦葵，对其种子中脂肪酸、氨基酸、微量元素、粗脂肪和粗蛋白含量进行了测定。脂肪酸和氨基酸的测定方法为GC-FID和HPLC法，有毒金属(Cd, Pb)及其他微量元素的测定方法为ICP-MS和ICP-AES。结果表明：(1)粗脂肪含量为16.160%～18.860%，均值为17.536%；在检测出的9种脂肪酸中，不饱和脂肪酸含量

Analysis of Nutritive Compositions in the Seeds of Kosteletzkya virginica

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.
