A new bicoumarin derivative, bidysoxyletine (1), was isolated from the leaves of Dysoxylum parasiticum (Osbeck) Kosterm. The structure of 1 was elucidated by analysis of NMR, UV, IR, HR-ESITOFMS, and DDFT approach using the B3LYP exchange-correlation function for C NMR and UV spectroscopic data. The results indicated that the structure of 1 possessed a dibenzonapthyrone skeleton.
从寄生 Dysoxylum（Osbeck）Kosterm 的叶子中分离得到一种新的双香豆素衍生物，bidysoxyletine（1）。通过分析 NMR、UV、IR、HR-ESITOFMS 和 DDFT 方法，使用 B3LYP 交换相关函数对 1 的 C NMR 和 UV 光谱数据进行计算，确定了 1 的结构。结果表明，1 的结构具有二苯并萘酮骨架。
