1.假石蒜碱用如下方法从6种石蒜属、5种水仙属植物中分得。卽用蓝氏铵盐使生物碱沉淀,溶于稀丙酮中,通过Zerolit 225(H型)。然后用4当量氨水洗脱该碱。另外我们也找到几种展开液,用它进行纸上层析,证明了微量的假石蒜碱。 2.检查24种石蒜科植物,结果找到如下四种石蒜碱含量较高,卽:迟花水仙Leucojum vernum L.0.53％,雪铃花水仙 Leucojum aestivum L.0.46％,矮喇叭水仙Narcissusincomparabilis Mill.0.33％,黄花石蒜Lycoris aurea Herb.0.20％。 1. False Lycorine was obtained from 6 species of Lycoris and 5 species of Narcissus by the following method. The alkaloids were precipitated with ammonium pentamine and dissolved in dilute acetone, passing Zerolit 225 (H type). Then the base was eluted with 4 equivalents of ammonia. In addition, we also found several developing solutions that were used for paper chromatography to prove trace amounts of pseudo-Lycinerine. 2. Examination of 24 species of Amaryllidaceae found that the following four contents of Lycorine were found to be higher: C. oleifera Leucojum vernum L. 0.53%, L. daffodil Leucojum aestivum L. 0.46%, dwarf narcissus Narcissus incomparabilis Mill .0.33%, Lycoris aurea Herb. 0.20%.
