Cubebs, oil

Cadinene is a trivial name of a number of isomers which occur in a wide variety of essential oils e.g. cubeb oil. Actually, it is derived from the Cade juniper Juniperus oxycedrus L.). The cadalane (4-isopropyl-1,6-dimethyldecahydro-naphthalene) carbon skeleton is the base. Prominent stereochemical isomers are a-cadinene 79, y-cadinene 80 and d-cadinene 81 (Structure 4.23). This group is also known as naphthalene-type sesquiterpenes. 

Cubeb Oil occurs as a colorless or light green to blue-green liquid with a spicy odor and a slightly acrid taste. It is the volatile oil obtained by steam distillation from the mature, unripe, sun-dried fruit of the perennial vine Piper cubeba L. (Fam. Piperaceae). It is soluble in most fixed oils and in mineral oil, but it is insoluble in glycerin and propylene glycol.

Patchouli oil is adulterated to a certain extent with the oU from other leaves which are fraudulently packed with patchouli leaves, such as basil leaves and the leaves of a Malayan plant, known as purpulut (Urena lobata). The leaves of Hyptis suaveoUns are also used as an adulterant. Sassafras (or heavy camphor oil) is sometimes found as an adulterant, as well as cubeb oil, cedar-wood oil, and —rarely— petroleum. 

Cubebol (295) occurs in a number of essential oUs. The richest source is Cubeb Oil Piper cubeba) in which it is present at 10% (350). Patent applications have been filed by Firmenich claiming it as a cooling and refreshing agent, in combination with other cooling agents [351-353].
