α-Vetivone is an organic compound that is classified as a sesquiterpene (derived from three isoprene units). It is a major component of the oil of vetiver, which is used to prepare certain high value perfumes.

α-Vetivone is isolated by steam distillation of the roots of the grass Vetiveria zizanioides. Two other components of this distillate are the sesquiterpenes khusimol and β-vetivone shown below.^[1]

Structure of khusimol, another fragrant component of the oil of vetiver.
Structure of β-vetivone, another fragrant component of the oil of vetiver.
