黄花棘豆毒性生物碱的分离与鉴定

The Isolation and Identification of Toxic Alkaloids from Yellowflower Crazyweed (Oxytropis ochrocephala )

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 quinolizidine alkaloids were isolated from the total alkaloid of the aerial part of oxytropis ochrocephala. They were idontified by UV, IR, EI-MS and physico- chemical pro perties as thermopsine, anagyrine, lupanine and sperteine. All of them were isolated for the first time from this plant.
