%X 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.
