Longifolene (MF: C₁₅H₂₄, MW: 204.35) is a tricyclic sesquiterpene hydrocarbon compound primarily extracted from heavy turpentine (the 250–270°C fraction), with a typical yield of 48%–67%. It appears as a colorless to pale yellow oily liquid with a pine-like aroma and exhibits chiral characteristics (specific rotation +42.73°), making it an important natural flavoring agent and organic synthesis intermediate.
