Caryophyllene, or (−)-β-caryophyllene, is a natural bicyclic sesquiterpene that is a constituent of some essential oils, especially clove oil and the oil from the stems and flowers of Syzygium aromaticum. It is usually found as a mixture with isocaryophyllene (the cis double bond isomer) and α-humulene (obsolete name: α-caryophyllene), a ring-opened isomer. Caryophyllene is notable for having a cyclobutane ring, a rarity in nature.
Caryophyllene is one of the chemical compounds that contributes to the spiciness of black pepper.
