Phellandrene is a pair of organic compounds, identified as alpha-phellandrene and beta-phellandrene, which share similar molecular structure and chemical properties. Both are classified as monoterpenes and are double-bond isomers. Alpha-phellandrene is a constituent of eucalyptus essential oil, while beta-phellandrene has been isolated from the oils of water fennel and Canadian balsam. Minty and citrus profiles make the phellandrenes popular components in commercial fragrances.
