Four new Amaryllidaceae alkaloids (1-4) possessing a homolycorine-type or a crinine-type skeleton have been isolated from the aerial part of Zephyranthes candida, and their structures were elucidated on the basis of spectroscopic data. The stereochemistry was elucidated by combination of NOESY correlations and CD analyses.
从葱莲（Zephyranthes candida）的地上部分分离得到了四个具有同半边莲碱型或石蒜碱型骨架的新石蒜科生物碱（1-4），并根据光谱数据阐明了它们的结构。通过 NOESY 相关和 CD 分析的组合阐明了立体化学。
