Abstract Phytochemical investigation of the bark of Guatteria olivacea R. E. Fries (Annonaceae) led to the isolation and identification of ten isoquinoline-derived alkaloids, including three phenanthrenes, atherosperminine, argentinine, and atherosperminine N-oxide; three aporphines, asimilobine, puterine, and discoguattine; two oxoaporphines, liriodenine and oxoputerine; and two tetrahydroprotoberberines, corypalmine and discretine. All these alkaloids are described for the first time in G. olivacea and their chemotaxonomic significance was discussed. The structure elucidation of these isolated alkaloids was established by extensive analyses of 1D and 2D NMR spectroscopy in combination with MS. The NMR data for atherosperminine, argentinine, and atherosperminine N-oxide were reviewed.

来自番石榴（番荔枝科）树皮的异喹啉衍生生物碱

摘要 对 Guatteria olivacea RE Fries (Annonaceae) 的树皮进行植物化学研究，分离和鉴定了 10 种异喹啉衍生的生物碱，包括三种菲、atherosperminine、阿根廷和 atherosperminine N-oxide；三种阿朴啡，阿西米​​洛宾、腐殖质和迪可加汀；两种氧代卟啉、鹅掌楸和氧化叶黄酮；和两种四氢原小檗碱，corypalmine 和 discretine。所有这些生物碱都是首次在 G. olivacea 中描述，并讨论了它们的化学分类学意义。这些分离的生物碱的结构解析是通过结合 MS 对 1D 和 2D NMR 光谱的广泛分析而建立的。审查了 atherosperminine、阿根廷和 atherosperminine N-氧化物的 NMR 数据。
