Phytochemical investigations on the methanol extract of Iris germanica resulted in the isolation of a new benzene derivative, 2'-methyl-6'-hydroxy cyclohexenyl-3-methyl-1-acetophenone ether (1). Further, another known benzene derivative, isopenol (2), also afforded two known isoflavones, irisolone (3) and irisolidone (4). The structure of the new compound was determined on the basis of spectroscopic data, including 2D-NMR experiments, while the known compounds were identified on the basis of their spectral data and existing literature evidence. The comparison of the spectral data of the irisolidone (3) with that reported for the molecule led us to revise some of the reported 1H-NMR chemical shift assignments.
对德国鸢尾甲醇提取物的植物化学研究导致分离出一个新的苯衍生物,2'-甲基-6'-羟基环己烯基-3-甲基-1-乙酰苯甲醚(1)。此外,另一个已知的苯衍生物,异戊醇(2),也得到了两个已知的异黄酮,鸢尾酮(3)和鸢尾苷元(4)。新化合物的结构是根据包括二维 NMR 实验在内的光谱数据确定的,而已知化合物则是根据其光谱数据和现有文献证据确定的。对鸢尾苷元(3)的光谱数据与文献报道的分子进行比较,使我们对一些报道的 1H-NMR 化学位移赋值进行了修正。
