测定了石蒜科15种石蒜烷型生物碱的~（13）CNMR谱，并对其化学位移进行了归属。从推导出的特定位移范围，可以建立5，10 b-乙菲啶骨架的完整氧化模式及其立体化学排列。
The13C NMR spectra of 15 Amaryllidaceae alkaloids with the crinane skeleton were measured and the chemical shifts unequivocally assigned. From the derived specific shift ranges, it is possible to establish both the complete oxygenation pattern of the 5, 10b‐ethanophenanthridine skeleton and its stereochemical arrangement.
