| Fractionation and analysis of Virginia cedarwood oil made clear that hydrocarbons (thujopsene, cedrene) and cedrol (week woody odor) hardly contribute to the specific odor of the oil. Fractions with woody, amber, phenolic, lactonic, and grapefruit aspects were found. Oxygenated sesquiterpenes like betulenal (with odor aspects of sandalwood and acetyl cedrene), funebrenal (8-cedren-15-al or α-cedrenal, woody), thujopsenal, chamigrenal, 8-cedren-10-one (musty, woody, mint, myrrh-like), and nootkatone (grapefruit-like) seem to contribute to the typical cedar character of the oil. \\ | Red cedarwood oil possesses a soft, pleasant, balsamic typical cedarwood odor.

| "α-Cedrene and thujopsene are the main products of the sesquiterpene fraction of red cedarwood oil (Juniperus virginiana L., Cupressaceae). While these sesquiterpenes possess only weak and uncharacteristic odors, some oxygenated derivatives are widely used in perfumery. The most important volume is the acetylation product of the sequiterpene fraction, sold under trade names such as //Vertofix Coeur (IFF)//, //Lignofix (Symrise)//, and //Cedartone V (Givaudan)//. It possesses an intense woody, ambery odor, which is attributed to a content of 5-10% of [1-aceto-7,10-ethano-4,4,7-trimethyl-1(9)-octalin, [[http://www.thegoodscentscompany.com/data/rw1046821.html|CAS 32388-56-0]]] ...\\ | "α-Cedrene and thujopsene are the main products of the sesquiterpene fraction of red cedarwood oil (Juniperus virginiana L., Cupressaceae).

| | "As cedarwood oil (Juniperus virginiana L.) is a by-product of the American timber industry, it is one of the most economical and abundant sources of sesquiterpenes. This makes it an attractive starting material for the synthesis of other odorants like Vertofix®. On the other hand, any attempt to introduce a new cedarwood odorant is a lost cause, simply because cedarwood oil is so inexpensive. (+)-Cedrol (155) is responsible for its soft, woody odour, typical of cedarwood, and it is isolated from the oil by fractional distillation followed by crystallization." \\ |
