Juniperus mexicana

Texas cedarwood oil is produced by steam distillation of chopped wood of the Texas cedar, Juniperus mexicana Schiede (Cupressaceae). It is a brown to reddish-brown, viscous liquid that may partially solidify at room temperature. It has a characteristic cedarwood odor.

The United States production of oil was derived from two species of wood. Virginia cedar wood oil is obtained by steam distillation of sawdust, waste wood, oil stumps, and chopped logs of eastern red cedar, Juniperus virginiana (19). Texas cedar wood oil is produced by steam distillation of chipped heartwood of Juniperus mexicana (15). The two oils are similar in chemical composition and they compete in the market place. The production of Virginia oil is about 140000 to 180000 kg/year and of the Texas oil about 450 to 900 million kg/year. The oils are used in the fragrance industries in products such as soaps, air fresheners, floor polishes, and sanitation supplies. The largest use for the oils is as a source of cedrol, their main component. Cedrol (1) is used to make cedryl acetate, which is used in perfumes. Cedar wood oils sell in the United States for 5 to 7/kg. 

Cedarwood Many varieties of cedarwood oil are obtained from different parts of the world. They are produced mainly by steam distillation of chipped heartwood, but some are produced by solvent extraction. The oils, which vary significantly in chemical composition, are used in perfumes as such, but the main uses are as distillation fractions and chemical derivatives. For the latter purposes, the most used oils, which are similar in composition, come from China (Cupressus funebris) and from Texas in the United States (Juniperus mexicana). The principal constituents of these oils are cedrene [11028-42-5] (4), thujopsene [470-40-6] (5), and cedrol [77-53-2] (6). The first two of these are obtained together by distillation and used mostly in the form of acetylated derivatives. Cedrol is used as such and, to a greater extent, as its acetate ester.

Production Both oils are produced by steam distillation from the wood of various Juniperus species (Cupressaceae) Virginia oil from the Southern red cedar , J. virginiana, growing mainly in the south east of the USA, Texas oil from species growing mainly in Texas such as, e. g., J. mexicana and J. deppeana. In the past the Virginia oil was a by-product from the processing of cedar wood for wardrobes, crates, and pencils. Today, the major part of the estimated annual production of ca. 15001 is distilled in Texas. 

There are several cedarwood oils with different physical and chemical properties. They are often referred to in the literatnre simply as cedarwood oil. The most common ones, cedarwood oil Virginia, cedarwood oil Texas, and cedarwood oil Atlas, are derived from J. virginiana, J. mexicana, and C. atlantica, respectively. Others such as cedarwood oil Himalaya, cedarwood oil East Africa, and cedarwood oil Japanese are obtained from other conifers (arctander). Juniperus ashei Buchh. is also used as a source of cedarwood oil other species (e.g., J. erythrocarpa Cory and J. scopulorum Sarg.) containing high oil content are potential sources. ...
