狭叶藜芦中活性成分的化学研究 Ⅲ.β₁-查茄碱的结构和狭叶藜芦碱丙、碱丁的部分结构研究

摘要: 自狭叶藜芦中首次分离出β₁-查茄碱和两个新碱狭叶藜芦碱丙、碱丁。根据光谱数据和衍生物的制备,测定了β₁-查茄碱的结构,初步推定了狭叶藜芦碱丙和碱丁的部分结构。

Abstract: β₁-Chaconine (Ⅴ₁₂), stenophylline C (Ⅴ₁₀) and stenophylline D (Ⅴ₁₄) were isolated from Veratrum stenophyllum Diels. The structure of β₁-chaconine and the partial structures of stenophylline C and stenophylline D were elucidated on the basis of chemical and spectrometric data (UV, IR, ¹HNMR, ¹³CNMR, MS). β₁-Chaconine has not been found previously in veratrum plants. Stenophylline C and stenophylline D have not been reported.
