  <name>2-Epi-alpha-cedrene</name>
  <description>2-epi-alpha-cedrene is a member of the class of compounds known as cedrane and isocedrane sesquiterpenoids. Cedrane and isocedrane sesquiterpenoids are sesquiternoids with a structure based on the cedrane or the isocedrane skeleton. Cedrane is a tricyclic molecules a 3,6,8,8-tetramethyl-1H-3a,7-methano-azulene moiety. Isocedrane is a rearranged cedrane arising from the migration of methyl group moved from the 6-position to the 4-position. 2-epi-alpha-cedrene can be found in sweet basil, which makes 2-epi-alpha-cedrene a potential biomarker for the consumption of this food product.</description>
