【摘要】 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ICPAES。结果表明 :(1)粗脂肪含量为 16 16 0 %~ 18 86 0 % ,均值为 17 5 36 % ;在检测出的 9种脂肪酸中 ,不饱和脂肪酸含量 (70 134% )大于饱和脂肪酸含量 (2 9 86 6 % ) ;(2 )粗蛋白含量在 2 2 74 0 %~ 2 8 2 4 0 %之间 ,17种氨基酸总含量为17 0 84 %~ 18 939g/ 10 0g,其中谷氨酸、天冬氨酸和精氨酸含量较高 ;(3)海滨锦葵种子中Ca、K、Mg、Fe和Zn含量分别为2 70 8g/kg、9 4 87g/kg、3 888g/kg、14 6 6 33mg/kg和 2 1 5 4 7mg/kg。海滨锦葵种子含有丰富的营养成分 ,具较高的营养价值 ,可作为油料、食品、饲料、保健品和其他工业用途的原料。

【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.
