The wood oil of C.nootkatensis contained nootkatene (50-60%), valencene (10-15%), carvacrol (5-8%), and nootkatone (2-5%).

„The essential oil of Alaska cedar heartwood is known to contain compounds which contribute to the remarkable durability of this species. While previous research has identified several compounds, a complete description of this oil, which has a „burnt-grape fruit“ odor, has not been undertaken. In this research a profile of the oil is given in which the major components are identified by GC-MS, isolation and spectroscopic techniques. 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 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. 1(10)-Eremophilen-11,12-epoxide apparently does not survive the condition of steam distillation. Nootkatol, eremophil-1(10),11-dien-13-ol and 1(10)-eremophilen-11,12-epoxide have not been previously reported in Alaska cedar. Nootkatol is a known compound having been reported in other plants. 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.“
[Xiong, Yeping. „Essential oil components of Alaska cedar heartwood.“ (2000)]
Cedarwood Alaska essential oil (steam distilled from fresh sawdust) combines spicy, aromatic and woody aspects with grapefruit notes, due to its nootkatene and nootkatone content. It is less camphoraceous and smoky, but stronger and longer lasting than regular Cedarwood EO (from Juniperus virginiana).
