Caryophyllene acetate is a natural sesquiterpene ester found in various plant sources, including clove, rosemary, and hops. It belongs to the class of compounds known as terpenes and possesses a distinctive spicy, woody aroma. Caryophyllene acetate is widely used in the fragrance and flavoring industries due to its pleasant scent. The compound is derived from caryophyllene, another terpene compound. It is formed by the esterification of caryophyllene with acetic acid. Caryophyllene acetate shares a similar carbon skeleton with other terpenes and contains an ester group, which contributes to its reactivity and biological activity.

Pharmacologically, caryophyllene acetate exhibits various potential therapeutic properties. It has been studied for its anti-inflammatory, analgesic, and antioxidant effects. Additionally, it has shown potential as an anxiolytic, suggesting its possible use in managing anxiety and stress-related disorders.

Caryophyllene acetate interacts with the endocannabinoid system (ECS) in the body. It is considered a selective agonist of the cannabinoid receptor type 2 (CB2), one of the two main cannabinoid receptors found in the ECS. Activation of the CB2 receptor by caryophyllene acetate can have anti-inflammatory and immune-modulating effects. Furthermore, caryophyllene acetate is also found in cannabis plants and contributes to the overall profile of terpenes and cannabinoids present in different cannabis strains. Its presence in cannabis, along with other terpenes, is thought to contribute to the entourage effect, a phenomenon where various compounds in cannabis work synergistically to produce enhanced therapeutic effects.
