What molecule am I?
cis-3-Hexen-1-ol is a natural product that is present in the leaves of most plants. It exudes the strong aroma of freshly cut grass and leaves, which accounts for its trivial name, “leaf oil”. Its odor can be the downfall of the plants that produce it because the compound attracts predatory insects.
Because cis-3-hexen-1-ol is found in a wide variety of fruits and vegetables (including carnation, grape, kiwi, corn, tomato, and tea), it is a valuable resource for imparting fruit and vegetable aromas to foods and for use in perfumes. But the compound is less expensive to manufacture than to extract from natural sources. The annual output of commercial cis-3-hexen-1-ol is ≈30 t.
So what is the Halloween connection? cis-3-Hexen-1-ol is the major aroma component of freshly cut pumpkins. Think about it as you start to carve your jack-o’-lantern this season. Happy Halloween!
