Thujopsene is a natural chemical compound, classified as a sesquiterpene, with the molecular formula C15H24.

Thujopsene is found in the essential oil of a variety of conifers, [2] in particular Juniperus cedrus and Thujopsis dolabrata in which it comprises around 2.2% of the weight of the heartwood. [3]


Thujopsene is biosynthesized from farnesyl pyrophosphate (FPP): [4]

<i>Cedrus</i> Genus of plants (coniferous trees)

Cedrus, common English name cedar, is a genus of coniferous trees in the plant family Pinaceae. They are native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean.

Juniper Genus of plants

Junipers are coniferous trees and shrubs in the genus Juniperus of the cypress family Cupressaceae. Depending on taxonomic viewpoint, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, from Ziarat, Pakistan, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of 16,000 ft (4,900 m) in southeastern Tibet and the northern Himalayas, creating one of the highest tree-lines on earth.

<i>Cedrus libani</i> species of plant

Cedrus libani, the cedar of Lebanon or Lebanon cedar, is a species of tree in the pine family Pinaceae, native to the mountains of the Eastern Mediterranean basin. It is a large evergreen conifer that has great religious and historical significance in the cultures of the Middle East, and is referenced many times in the literature of ancient civilisations. It is the national emblem of Lebanon and is widely used as an ornamental tree in parks and gardens.

<i>Cedrus deodara</i> Species of plant

Limonene Chemical compound

Limonene is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the oil of citrus fruit peels. The D-isomer, occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing. It is also used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products. The less common L-isomer is found in mint oils and has a piny, turpentine-like odor. The compound is one of the main volatile monoterpenes found in the resin of conifers, particularly in the Pinaceae, and of orange oil.

<i>Juniperus cedrus</i> species of plant

Juniperus cedrus, the Canary Islands juniper, is a species of juniper, native to the western Canary Islands and Madeira, where it occurs at altitudes of 500–2400 m. It is closely related to Juniperus oxycedrus of the Mediterranean region and Juniperus brevifolia of the Azores.

Juniper berry spice, herbal drug

A juniper berry is the female seed cone produced by the various species of junipers. It is not a true berry but a cone with unusually fleshy and merged scales, which gives it a berry-like appearance. The cones from a handful of species, especially Juniperus communis, are used as a spice, particularly in European cuisine, and also give gin its distinctive flavour. Juniper berries may be the only spice derived from conifers.

<i>Juniperus phoenicea</i> species of plant

Juniperus phoenicea, the Phoenicean juniper or Arâr, is a juniper found throughout the Mediterranean region, from Morocco and Portugal east to Italy, Turkey and Egypt, south on the mountains of Lebanon, the Palestine region and in western Saudi Arabia near the Red Sea, and also on Madeira and the Canary Islands. It mostly grows at low altitudes close to the coast, but reaches 2,400 metres (7,900 ft) altitude in the south of its range in the Atlas Mountains. It is the vegetable symbol of the island of El Hierro.

<i>Juniperus brevifolia</i> species of plant

Juniperus brevifolia, the Azores juniper, is a species of juniper, endemic to the Azores, where it occurs at altitudes of 240–800 m, rarely up to 1,500 m. It is closely related to Juniperus oxycedrus of the Mediterranean region and Juniperus cedrus of the Canary Islands. It is threatened by habitat loss.

ACTA2 protein-coding gene in the species Homo sapiens

ACTA2 is an actin protein with several aliases including alpha-actin, alpha-actin-2,aortic smooth muscle or alpha smooth muscle actin. Actins are a family of globular multi-functional proteins that form microfilaments. ACTA2 is one of 6 different actin isoforms and is involved in the contractile apparatus of smooth muscle. ACTA2 is extremely highly conserved and found in nearly all mammals.
