Nine new sesquiterpenoid esters (Ejap-2, -3, -4, -6, -7, -10, -12, -13, and -14) have been isolated from Euonymus japonicus, besides a known compound (Ejap-5). Structures of the isolated substances were deduced from 1D, as well as 2D COSY and NOESY, 1H n.m.r. and mass spectra. The position of the benzoyl groups among the other esterifying moieties was located by X-ray diffraction for Ejap-2, -3, -4, -5, -6, and -10. Among the sesquiterpene cores, 8-deoxypolyalcohol C, 8-epi-polyalcohol C, 9-epi-alcohol A, and 4,12-dideoxyeuonyminol have been obtained in neither a synthetic nor a natural product until now.
