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]
