从宁夏有毒植物黄花棘豆的地上部分总生物碱中首次分得4种生物碱单体，经光谱分析并与标准品或文献对照，证实它们同属喹诺里西啶（quinolizidine）衍生物类，分别鉴定为黄华碱、臭豆碱、白羽扇豆碱和鹰爪豆碱。
Four kinds of alkaloid monomers were obtained from the total alkaloids of aerial parts of the poisonous plant Oxytropis sinensis in Ningxia for the first time. Spectral analysis and comparison with standard products or literature confirmed that they belong to the quinolizidine derivatives.
