对国外黄芪属植物的叶片进行了有毒脂肪族硝基化合物的存在和类型检测。在92种被检查的物种中，22种(24%)对硝基化合物检测呈阳性，70种(76%)对硝基化合物检测呈阴性。3种含氮植物：北黄芪、伊法哈尼察黄芪和角果黄芪。合成3-硝基-1-丙醇(3-NPOH)。其他硝基物种合成了3-硝基丙酸(3-NPA)。10个分类断面中含硝基物种比例较高。黄芪的化学分类关系表明，这10个组中的其他物种中的大多数(如果不是全部)都会合成硝基
Leaves of foreign Astragalus species were examined for the presence and type of poisonous aliphatic nitro compounds. Twenty-two (24%) of the 92 species examined tested positive for nitro compounds and 70 (76%) tested negative. Three nitrobearing species, Astragalus bodeanus Fisch., Astragalus isfahanicus Boiss., and Astragalus siliquosus Boiss. synthesized 3-nitro-1-propanol (3-NPOH). The other nitro-bearing species synthesized 3-nitropropionic acid (3-NPA). Ten taxonomic sections had a high percentage of nitro-bearing species. Chemotaxonomic relationships in Astragalus suggest that most, if not all, of the other species in these 10 sections would synthesize nitro
