摘 要 ：银砂槐(Ammodendron bifolium(Pall.) Yakovl.)为一种分布于我国新疆的珍稀沙生植物。为了研究银砂槐对沙漠环境的适应特性，本文检测了该物种种子中主要有机物的种类及其含量。结果如下：（1）碳水化合物、可溶性蛋白质和粗脂肪分别占种子干重的16.8%、23.7%和15.5%。（2）碳水化合物中可溶性糖占种子干重的10.1%，蔗糖占可溶性糖的43.4%。（3）蛋白质中的氨基酸和游离氨基酸分别占种子干重的26.5%和0.4%。（4）不饱和脂肪酸占总脂肪含量的90%以上，油酸、亚油酸是其主要成分。

Abstract:Ammodendron bifolium(Pall.) Yakovl. is a rare psammophyte distributed in Xinjiang of China. In order to study the adaptation of the species to desert environment, the contents of main organic compounds in its seeds were determined. Carbohydrate, soluble protein and crude fat accounted for 16.8%, 23.7% and 15.5% of seed dry weight respectively. Soluble carbohydrate accounted for 10.1% of seed dry weight, and sucrose accounted for 43.4% of soluble carbohydrate content. Contents of amino acids in proteins and free amino acids accounted for 26.5% and 0.4% of seed dry weight, respectively. Unsaturated fatty acid was more than 90% of total fat content, and oleic acid and linoleic acid were its main component.
