![]() However, eremophil-1(10),11-dien-13-ol and 1(10)-eremophilen-11,12-epoxide represent new chemical structures to science being described here for the first time.“ Nootkatol is a known compound having been reported in other plants. ![]() Nootkatol, eremophil-1(10),11-dien-13-ol and 1(10)-eremophilen-11,12-epoxide have not been previously reported in Alaska cedar. 1(10)-Eremophilen-11,12-epoxide apparently does not survive the condition of steam distillation. In addition, it was found that the diethyl ether extract of the heartwood contained 1(10)-eremophilen-11,12-epoxide as a major component in addition to the compounds found in the steam distilled essential oil. The major components of the steam distilled essential oil were identified as nootkatin, nootkatone, valencene, nootaktene, carvacrol, methyl carvacrol, nootkatol, and eremophil-1(10),11-dien-13-ol. In this research a profile of the oil is given in which the major components are identified by GC-MS, isolation and spectroscopic techniques. While previous research has identified several compounds, a complete description of this oil, which has a „burnt-grape fruit“ odor, has not been undertaken. „The essential oil of Alaska cedar heartwood is known to contain compounds which contribute to the remarkable durability of this species.
