Abstract
A new pyrrolizidine alkaloid, named crotavitelin, was isolated from fruits of Crotalaria vitellina, Fabaceae (Papilionoideae). The structure was established by spectroscopic techniques such as one-dimensional and two-dimensional NMR, IR, and MS.
摘要
从豆科（蝶形花亚科）野百合属植物黄野百合的果实中分离得到一个新的吡咯里西啶生物碱，命名为野百合碱。通过一维和二维 NMR、IR 和 MS 等光谱技术确定了其结构。
