+ | "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." | ||
