Abstract The phytochemical investigation of stems of Fissistigma glaucescens (Hance) Merr. led to the isolation of a new aristolactam derivative aristolactam AIb (1), together with eleven known aristolactam derivatives (2–12). Structure elucidation of these compounds were performed on the basis of NMR spectral data and MS. Compounds 2–7 were isolated from the F. glaucescens for the first time. The chemotaxonomic significance of the isolates was also discussed.

来自 Fissistigma glaucescens 的马兜铃内酰胺衍生物

摘要 Fissistigma glaucescens (Hance) Merr 茎的植物化学研究。导致分离出一种新的马兜铃内酰胺衍生物马兜铃内酰胺 AIb (1)，以及 11 种已知的马兜铃内酰胺衍生物 (2-12)。这些化合物的结构解析是在 NMR 光谱数据和 MS 的基础上进行的。化合物 2-7 为首次从 F. glaucescens 中分离得到。还讨论了分离物的化学分类学意义。
