  • Applications

    β-Caryophyllene (CAS 87-44-5) is a fragrant sesquiterpene abundant in basil, black pepper and hops, distinguished by its selective binding to the CB2 cannabinoid receptor, which imparts anti-inflammatory, analgesic and neuroprotective activity; in pharmaceuticals it is being explored as a co-active for arthritis, metabolic syndrome, anxiety disorders and neurodegenerative diseases, while in cosmetics β-caryophyllene soothes irritation, promotes skin regeneration and offers natural deodorising effects; in foods and beverages the compound provides a warm spicy note, acting as a safe flavour additive that deepens taste complexity and serves as a natural antioxidant preservative; additionally, β-caryophyllene functions as a semiochemical in agriculture, repelling pests and attracting beneficial insects, and as a bio-derived solvent in perfumery and an innovative carrier matrix for nano-delivery systems, illustrating the multi-sector potential of this sustainable plant-origin ingredient.
