Guaiene
Guaienes are a series of closely related natural chemical compounds that have been isolated from a variety of plant sources. The guaienes are sesquiterpenes with the molecular formula C15H24. α-Guaiene is the most common and was first isolated from guaiac wood oil from ''Bulnesia sarmientoi''. The guaienes are used in the fragrance and flavoring industries to impart earthy, spicy aromas and tastes. Joint FAO/WHO Expert Committee on Food Additives See also *Guaiol

Sesquiterpene
Sesquiterpenes are a class of terpenes that consist of three isoprene units and often have the molecular formula C15H24. Like monoterpenes, sesquiterpenes may be cyclic or contain rings, including many unique combinations. Biochemical modifications such as oxidation or rearrangement produce the related sesquiterpenoids. Sesquiterpenes are found naturally in plants and insects, as semiochemicals, e.g. defensive agents or pheromones. Biosynthesis and examples The reaction of geranyl pyrophosphate with isopentenyl pyrophosphate results in the 15-carbon farnesyl pyrophosphate (FPP), which is an intermediate in the biosynthesis of sesquiterpenes such as farnesene. Cyclic sesquiterpenes are more common than cyclic monoterpenes because of the increased chain length and additional double bond in the sesquiterpene precursors. In addition to common six-membered ring systems such as the ones found in zingiberene and bisacurone, cyclization of one end of the chain to the other end can l ...

Oil Of Guaiac
Oil of guaiac is a fragrance ingredient used in soap and perfumery. Despite its name it does not come from the ''Guaiacum'' tree, but from the palo santo tree (''Bulnesia sarmientoi''). Oil of guaiac is produced through steam distillation of a mixture of wood and sawdust from palo santo. It is sometimes incorrectly called guaiac wood concrete. It is a yellow to greenish yellow semi-solid mass which melts around 40–50 °C. Once melted, it can be cooled back to room temperature yet remain liquid for a long time. Oil of guaiac has a soft roselike odour, similar to the odour of hybrid tea roses or violets. Because of this similarity, it has sometimes been used as an adulterant for rose oil. Oil of guaiac is primarily composed of 42–72% guaiol, bulnesol, δ- bulnesene, β- bulnesene, α-guaiene, guaioxide and β- patchoulene. It is considered non-irritating, non-sensitizing, and non-phototoxic to human skin. Oil of guaiac was also a pre-Renaissance remedy to syphilis. ...

Bulnesia Sarmientoi
''Bulnesia sarmientoi'' (recently reclassified as ''Gonopterodendron sarmientoi'') is a tree that inhabits a part of the Gran Chaco area in South America, around the Argentina-Bolivia-Paraguay border. Its wood is often traded as "Paraguay ''lignum vitae''", since it has properties and uses similar to the "true" ''lignum vitae'' trees of genus ''Guaiacum'', which are close relatives. Another trade name is "vera" or "verawood", which may also refer to the even more closely related '' B. arborea''. Another common but rather ambiguous name is ''palo santo'' (Spanish: "holy stick"), which it shares with the species ''Bursera graveolens''. ''Bulnesia sarmientoi'' heartwood is brown, black, and green (varying in color from light olive green to chocolate brown), with streaks. The sapwood is mostly thin and light yellow. The basic specific gravity of this wood is between 0.92 and 1.1 g/cm3. Conservation ''Bulnesia sarmientoi'' was listed as endangered in the 2018 publication of the IU ...
