Chamaecyparis Cupressaceae

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.

Production By steam distillation from the wood of the Chinese red pine Chamaecyparis funebris (Cupressaceae). The annual production amounts to ca. 200-3(X) t. CompositionThe main components of all mentioned oils are the sesquiterpene compounds a- cedrene (ca. 10-25%), tIiM/opsene(ca.20-35%),and cedrol(c. 20-40%, in Chinese oil only 10-15%). 

CI oH I gO, Mr 154.25. A bicyclic monoterpene with the fenchane structure that was first detected in the turpentine oil of the pine Pinus palusiris. Various stereoisomers and their mixtures occur in numerous plant oils, e.g., (-)-j8-F. (oil, [a]o° -31°), in the essential oil of Lawson s cypress (Chamaecyparis lawsoniana, Cupressaceae) or (+)-a-F. (cryst., mp. 47-47.5 °C, [a] +12.5°) from the marsh resin obtained from peat bogs (= kauri resin of the tree Agathis australis, Araucaria-ceae). Fenchyl acetate is used in perfumes with a coniferous nuance. 

C oH,g, Mr 138.25. Parent skeleton of the bicy-clo[3.1. Ojhexane monoterpenes. Of the four possible optically active forms only (-F)-(l/f,4/ ,5/f)-T., bp. 151 °C, [aJo f87° (neat), occurs in nature, e.g., in the essential oil of the fresh leaves of Chamaecyparis for-mosensis (Cupressaceae), a tree indigenous to Taiwan and known as Benihio or Beniki. 

Fenchane derivatives occur as fenchones and fenchols in several ethereal oils. Oil of fennel, obtained from the dried fruit of Foeniculum vulgare (Umbelliferae), contains up to 20 % (+)-fenchone, and is associated with limonene, phellandrene and a-pinene. (-)-Fenchone is isolated from the tree of life Thuja occidentalis (Cu-pressaceae), which is cultivated as hedges. The dextrorotatory enantiomer of a-fenchol with an endo OH, requested in perfumery, as well as its stereoisomers are found in fresh lemon juice, in oil of turpentine obtained from Pinus palustris (Pina-ceae), in ethereal oils originating from the Lawson white cedar Chamaecyparis lawsoniana (Cupressaceae) and other plant families such as Ferula, Juniperus, and Clausena species... 

P-bisabolene. The latter also oeeurs in Chamaecyparis nootkatensis (Cupressaceae) and in the Sibirian pine tree Piims sibirica (Pinaceae). (+)-a- and (+)-p-bisabolol are fragrant sesquiterpenes found in the essential oils of various plants they also contribute to the odors of camomile and of bergamot oil from unripe fruits of Citrus aurantium var. bergamia (Rutaceae) growing in southern Italy. 

Connecting the bonds C-l-C-6 and C-6-C-10 in famesane formally produces the spiro[4,5]decane basic skeleton of acorane. The name of this class of sesquiterpenes stems from the Acorus species. (-)-4-Acoren-3-one, for example, has been isolated from Acorus calamus (Calamus, Araceae) and from the carrot Daucus carota (Umbelliferae). The oil of calamus (oil of sweet flag) from the rhizome of Acorus calamus with its warm and spicy odor and pleasant bitter taste is predominantly used in perfumery and as a minor (possibly carcinogenic) ingredient of vermouth, some flavored wines and liqueurs. (+)-3,7(ll)-Acoradiene is a constituent of juniper Juniperus rigida its enantiomer occurs in Chamaecyparis nootkatensis (Cupressaceae). 

The EO of Chamaecyparis obtusa (Siebold and Zucc.) Endl. (Cupressaceae) showed promising decrease of the production of LPS-induced PGE-2 and peripheral blood mononuclear cells. The expression of TNF-a and COX-2 was also inhibited. These results showed promising antiin ammatory activity (An et al., 2013).
