bark contained a wide array of known furocoumarins and furoquinoline alkaloids. In addition, 1-hydroxy-3-methoxy- N -methylacridone was obtained from E. litoralis bark and a new natural 2-quinolone alkaloid, formulated as 3,3-diisopropyl- N -methyl-2,4-quinoldione, was obtained from E. flava wood. The structure was assigned from spectroscopic considerations and conversion to N -methylhaplofoline.
摘要 已确定三种墨西哥 Esenbeckia 物种的化学成分。Rutaevin 是存在于所有三个物种 E. litoralis、E. flava 和 E. berlandieri 种子中的主要柠檬苦素。外壳、树叶、木材和树皮含有多种已知的呋喃香豆素和呋喃喹啉生物碱。此外,从海参树皮中提取了1-羟基-3-甲氧基-N-甲基吖啶酮,并得到了一种新的天然2-喹诺酮生物碱,配制成3,3-二异丙基-N-甲基-2,4-喹诺二酮。来自 E. flava wood。该结构是从光谱考虑和转化为 N-甲基haplofoline 指定的。
