| 摘 要： | 从没药氯仿提取物中分离得到一呋喃倍半萜类化合物：2-甲氧基-5-乙酰氧基呋喃吉马-1(10)E-烯-6-酮．通过1D NMR和2D NMR（1H-1H COSY，HSQC和HMBC）等技术确定了该化合物的结构，利用2D NMR技术对其核磁共振信号进行了全归属，修正了文献中的归属错误. 通过NOESY实验以及偶合常数的分析，确定了其结构中1，10位双键和甲氧基、乙酰氧基、 甲基等基团的相对构型.

| Abstract: | A furanosesquiterpenoid, 2-methoxy-5-acetoxy-furanogermacr-1(10)E-en-6- one was isolated from the CHCl3 extrct of myrrh. Its structure was established by its 1D and 2D NMR (i.e, 1H-1H COSY, HSQC and HMBC) spectra. The 1H and 13C chemical shifts of the compound were assigned. The relative stereochemistry of the 1, 10-double bond and that of the methoxyl, methyl, and acetoxy groups were determined by NOESY experiments and analyses of the coupling constants. |
