Guaiene

Guaienes are a series of closely related natural chemical compounds that have been isolated from a variety of plant sources. The guaienes are sesquiterpenes with the molecular formula C₁₅H₂₄. α-Guaiene is the most common and was first isolated from guaiac wood oil from Bulnesia sarmientoi.^[4] The guaienes are used in the fragrance and flavoring industries to impart earthy, spicy aromas and tastes.^[1][5]
