从埃及产的Pancratium maritimum中分离得到两个2-羟基菲啶生物碱，经光谱和化学方法鉴定为恩格列明和泽夫甜菜碱。zefbetaine的鉴定得到了其从假石蒜碱的部分合成的支持，并通过与其非天然异构体isozefbetaine的比较，isozefbetaine又从sternbergine制备。
Two 2-oxyphenanthridinium alkaloids have been isolated from Egyptian Pancratium maritimum and identified as ungeremine and zefbetaine using spectroscopic and chemical methods. The identification of zefbetaine was supported by its partial synthesis from pseudolycorine and by comparison with its unnatural isomer, isozefbetaine, which was in turn prepared from sternbergine.
