„Its timber is widely described as possessing a very strong scent that is reminiscent to that of sandalwood
(Santalum spp.) and historically its essential oil has been exploited commercially by the perfume industry… The eremophilanes were first reported from the wood oil of E. mitchellii in 1932 by Bradfield and co-workers… The heartwood yielded an aromatic oil (2.2 % w/w) that was also predominantly composed of sesquiterpenes. Three of the major constituents identified in the heartwood oil were eremophilone (42.9%), santalcamphor (17.5%), and 9-hydroxy-7(11),9-eremophiladien-8-one (18.0%) and their occurrence in E. mitchellii has been well documented (Bradfield 1932a, 1932b; Massy-Westropp and Reynolds 1966; Adams 2007). A fourth major constituent, the novel 9-hydroxy-1,7(11),9-eremophilatrien-9-one proved to be very unstable. These four major constituents account for 80% of the wood oil.“

Main components of commercial buddha wood oils were eremophilone (34.3-35.8%), 2-hydroxyeremophilone (24.3-25.7%), 8-hydroxydihydroeremophilone (13.8-14.2%), 9-hydroxy-1,7(11),9-eremophilatrien-8-one (5.4-6.3%), and 8-hydroxy-1,11-eremophiladien-9-one (1.3%).
