Two new alkaloids (1, 2) were isolated from the whole plants of Crinum asiaticum var. sinicum together with seven known alkaloids. The structures of the new alkaloids were elucidated by spectroscopic analyses and chemical conversions from known alkaloids. New alkaloid 1 was isolated for the first time as a natural product, although it has been prepared as a synthetic product.
从中国水仙全草中分离得到两种新生物碱（1、2）以及七种已知生物碱。通过光谱分析和从已知生物碱进行化学转化确定了新生物碱的结构。新生物碱1虽然已通过合成方法制备，但此次是首次作为天然产物被分离得到。
