Adulteration is done by either turpentine oil or a and p pinene. Further, blending is done using 5 3 carene and cedrol from cedarwood Chinese type. AFNOR (1992) presents data in the standard NF T 75 -254. Using chiral GC as his method of analysis, Casabianca (1996) determined that the enantiomeric ratio of a-thujene in cypress oil was as follows ( / ) (+) a thujene (45%) (15) () a-thujene (55%). 

Chinese cedarwood oil is similar in composition to Texas cedarwood oil (see below). Chinese cedarwood oil is obtained by steam distillation of Chamaecyparis funebris (Endl.) France (Cupressusfunebris Endl., Cupressaceae), which is a weeping cypress, indigenous to China. Commercial Chinese cedarwood oil is a colorless to slightly yellow oil with an odor more smoke-like than the American oils. 

Two main families of cedarwood oils are used in perfumery. The first is extracted from trees of the family Juniperus. These oils are known as English, Texan or Chinese cedarwood and their components are derived from the cedrane and thujopsane groups of sesquiterpenes. Atlas and Himalayan cedarwoods are obtained from Cedrus species and their terpenes are mostly from the bisabolane family. The cedrane-thujopsane derivatives are much more widely used than the bisabo-lanes. 

There are two main types of cedarwood sources for perfumery. One comprises plants of the juniperus family and the other of the cedrus family. The former are known as English, Texan or Chinese cedarwood and are produced principally in China and U.S.A. The leaf oils are extracted from this family. Chemically, the major components of these oils are based on the cedrane skeleton. The products obtained from members of the cedrus family are known as Atlas or Himalayan cedarwoods. They are produced in North Africa and the Himalayas and the chemical structure of their major components are based on the bisabolane skeleton. 

B) Chinese cedarwood oil A clear, mobile, mostly yellowish oil with a typical odor of cedarwood but with a much more smoky and fatty note than the American oils.
