第一个二氨基瑞香属生物碱daphnipaxinin（1）是从瑞香属植物Daphniphyllum paxianum Rosenth的茎中分离得到的，它具有前所未有的六环稠合骨架，沿着已知的生物碱daphnicyclidin A（2）。通过波谱方法，特别是二维核磁共振技术和CID分析，确定了化合物1的结构和绝对立体化学。
The first diamino Daphniphyllum alkaloid, daphnipaxinin (1), with an unprecedented hexacyclic fused skeleton, along with a known alkaloid, daphnicyclidin A (2), was isolated from the stem of Daphniphyllum paxianum Rosenth. The structure and absolute stereochemistry of 1 were established by spectral methods, especially two-dimensional NMR techniques and CID analysis.
