beta-pinene (β-pinene) is a monoterpene, an organic compound found in plants. It is one of the two isomers of pinene, the other being α-pinene. It is colorless liquid soluble in alcohol, but not water. It has a woody-green pine-like smell.
This is one of the most abundant compounds released by forest trees.[1] If oxidized in air, the allylic products of the pinocarveol and myrtenol family prevail.[2]
Plants that contain β-pinene
Many plants from many botanical families contain the compound, including:
- Cuminum cyminum[3][4]
- Humulus lupulus[5]
- Pinus pinaster[2]
