Common NameGermacrene B
DescriptionGermacrene B, also known as germacratriene, belongs to the class of organic compounds known as germacrane sesquiterpenoids. These are sesquiterpenoids having the germacrane skeleton, with a structure characterized by a cyclodecane ring substituted with an isopropyl and two methyl groups. Thus, germacrene b is considered to be an isoprenoid lipid molecule. Germacrenes are a class of volatile organic hydrocarbons, specifically, sesquiterpenes. The essential oil of the red deadnettle (Lamium purpureum) is characterized by its high contents of germacrene D, as is Clausena anisata. Germacrene B is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Germacrene B is an earthy, spicy, and woody tasting compound. Outside of the human body, Germacrene B has been detected, but not quantified in, several different foods, such as citrus, common oregano, limes, and pepper (spice). This could make germacrene b a potential biomarker for the consumption of these foods. Two prominent molecules are germacrene A and germacrene D.Germacrene has five isomers. Germacrene B is found in Aspergillus candidus. Germacrenes are typically produced in a number of plant species for their antimicrobial and insecticidal properties, though they also play a role as insect pheromones.
