植物引种[P.I.]对在西部地区植物引种站[华盛顿，美国]生长的用于初步评价和种子增加的收集物的粗蛋白、粗纤维、单宁、脂肪酸盐和容易检测的生物碱进行评价。68份黄芪种质资源代表33个种。1份未鉴定材料的粗蛋白含量为8.2-24.2%，粗纤维含量为11.3-28.6%，单宁含量为4.2- 10.0mg/g，脂肪酸含量为0.15-1.10。具有> 18%粗蛋白和< 28%粗纤维的物种（即，与优质苜蓿干草相当）和可接受的单宁和草酸水平是A. canadensis，P.I. 19978和A.长角豆属（siliquosus）、P.I. 330696.没有一个处理过的加入给出了一个积极的德拉根多夫试剂颜色测试生物碱。报告的一些物种是硒累积者和/或含有可能对食草动物造成损害的有毒硝基化合物。A.长角果菌属是一种含硝基化合物的物种，对硒有富集作用。
Plant introduction [P.I.] collections grown at the Western Regional Plant Introduction Station [Washington, USA] for preliminary evaluation and seed increase were evaluated for crude protein, crude fiber, tannin, oxalates and readily detectable alkaloids. Sixty-eight Astragalus accessions representing 33 spp. and 1 unidentified accession had a range of 8.2-24.2% crude protein, 11.3-28.6% crude fiber, 4.2-10.0 mg/g tannin, and 0.15-1.10 oxalates. Species with > 18% crude protein and < 28% crude fiber (i.e., comparable to good quality alfalfa (Medicago sativa) hay) and acceptable levels of tannin and oxalate were A. canadensis, P.I. 19978 and A. siliquosus, P.I. 330696. None of the accessions treated gave a positive Dragendorff reagent color test for alkaloids. Some of the species reported are Se accumulators and/or contain toxic nitro-compounds that may be damaging to grazing animals. A. siliquosus is a species that contains nitro-compounds and will accumulate Se.
