黄花棘豆是我国西北危害牲畜的植物之一,它的化学成份尚未进行过研究。我们从黄花棘豆地上部分分离出四种黄酮化合物,经紫外、红外、核磁共振氢谱和质谱分析以及对它们各对应的乙酰衍生物的核磁共振氢谱和质谱分析,鉴定它们分别为槲皮素、鼠李柠檬素、异槲皮甙和鼠李柠檬素-3-葡萄糖甙。鼠李柠檬素-3-葡萄糖甙在棘豆属植物中首次发现,它的存在对我国棘豆属植物的化学分类将有一定的意义。 Oxytropis chinensis is one of the plants that harm livestock in Northwest China. Its chemical composition has not been studied. We isolated four flavonoids from the aerial parts of O. spinulosa, identified by UV, IR, 1 H NMR and MS, and their corresponding acetyl-derivatives by NMR and MS analysis. , Rhizoma Limonin, Isoquercitrin, and Rhombodin-3-Glucosidase. The first discovery of the lemon citrin-3-glucoside in the genus Oxytropis has certain significance for the chemical classification of the Oxytropis plants in China.
