Cubebene
Cubebenes are a pair of chemical compounds, classified as sesquiterpenes, first isolated from Piper cubeba berries, known as cubebs.
The volatile oil from the distillation of cubebs is a pale green or blue-yellow viscous liquid with a warm woody, slightly camphoraceous odor[1] consisting of cubebene which comes in two forms, α- and β-cubebene, both with the molecular formula C15H24.[2] They differ only in the position of a double bond which is endocyclic (part of the five-membered ring) in α-cubebene, but exocyclic in β-cubeαbene.[3]
Additional plant sources
A 2022 study detected α-cubebene in samples of oleoresin from three pine species (Pinus elliottii, Pinus pinaster, Pinus tropicalis) via mass spectrometry. [4]
α-cubebene was detected in Vitis vinifera Lemberger cultivar fruit via gas chromatography-mass spectrometry.[5]
