从新疆藜芦(Veratrum lobelianum Bernh)中分离得到三种生物碱一碱(Ⅰ),碱(Ⅱ),碱(Ⅲ).通过对它们进行IR,~1HNMR,MS等分析。碱(Ⅰ)为藜芦嗪碱(Verazine),碱(Ⅱ)为藜芦酰棋盘花胺(Veratoylzygadenine),碱(Ⅲ)为计莫林碱(Germerine). 碱(Ⅰ)m.p166—168℃,经质谱m/e:397(M~+)和元素分析,分子式为C_(27)H_(43)NO, Three kinds of alkaloids (I), alkalis (II) and alkalis (III) were isolated from Veratrum lobelianum Bernh. IR, 1H NMR and MS analysis were performed on them. Base (I) is Verazine, Base (II) is Veratoyl zygadenine, Base (III) is merline (Germerine), Base (I) m.p166-168 °C, mass spectrometry m/e: 397 (M~+) and elemental analysis, molecular formula C_(27)H_(43)NO,
