采用国标方法对复羽叶栾树种仁的脂肪酸以及氨基酸组成进行分析测定。结果表明:复羽叶栾树种仁的粗脂肪含量为11. 4%,种仁油中含有15种脂肪酸,主要为花生一烯酸（45. 4%）、油酸（23. 7%）、亚油酸（9. 2%）、棕榈酸（6. 1%）、芥酸（5. 6%）,不饱和脂肪酸含量达87. 20%,单不饱和脂肪酸含量为74. 95%;种仁粗蛋白质含量为26. 2%,种仁蛋白中氨基酸含量为19. 29%;在种仁蛋白中至少有16种氨基酸,其中必需氨基酸含量占氨基酸总量的33. 59%,药效氨基酸占70%。研究表明,复羽叶栾树种仁既可作为生产生物柴油、药物和化妆品的原料,也是良好的蛋白质和食用油资源,具有广阔的开发前景。

The compositions of fatty acid and amino acid of Koelreuteria bipinnata seed kernel were analyzed according to the national standard methods. The results showed that the content of crude fat in K. bipinnata seed kernel was 11.4%. Fifteen kinds of fatty acids were identified in K. bipinnata seed kernel oil,mainly including eicosenoic acid ( 45.4%), oleic acid ( 23.7%), linoleic acid ( 9.2%), palmitic acid ( 6.1%) and erucic acid ( 5.6%). Unsaturated fatty acids were up to 87.20%,and monounsaturated fatty acids accounted for 74.95%. The contents of crude protein and amino acid of K. bipinnata se...
